NASA revises shuttle schedule  

NASA Astrophysics Data System (ADS)

The new schedule for Space Shuttle missions and expendable launch vehicles (ELV's) calls for a 7-month delay in sending up the Hubble Space Telescope. NASA was forced to put off launching the telescope until February 1990 to keep the Magellan and Galileo missions within their narrow launch windows. The first post-Challenger shuttle launch is now scheduled for late this month. Discovery's most recent delays were due to a hydrogen leak discovered July 29 that has still not been corrected and an engine valve malfunction during an August 4 test fire.

NASA nixes Centaur launches from shuttle  

NASA Astrophysics Data System (ADS)

James C. Fletcher, the administrator of the National Aeronautics and Space Administration (NASA) announced on June 19, 1986, that because of safety considerations, the space shuttle will not be used to launch the Centaur Upper Stage. The Ulysses and Galileo missions, which were originally to have been launched in May 1986, would have been launched from the shuttle with the Centaur rocket (Eos, November 19, 1985, p. 1183; February 4, 1986, p. 57). The Galileo craft is to explore Jupiter; Ulysses is a joint mission of the European Space Agency (ESA) and NASA that is to orbit the sun around its poles, outside of the “ecliptic plane” where the planets lie. The decision seems likely to delay further the two missions, which were already delayed by the suspension of shuttle launches after the explosion of the space shuttle Challenger on January 28, 1986.

The epistemic integrity of NASA practices in the Space Shuttle Program.  

PubMed

This article presents an account of epistemic integrity and uses it to demonstrate that the epistemic integrity of different kinds of practices in NASA's Space Shuttle Program was limited. We focus on the following kinds of practices: (1) research by working engineers, (2) review by middle-level managers, and (3) communication with the public. We argue that the epistemic integrity of these practices was undermined by production pressure at NASA, i.e., the pressure to launch an unreasonable amount of flights per year. Finally, our findings are used to develop some potential strategies to protect epistemic integrity in aerospace science. PMID:23432770

Neutron Diffraction Characterization of Residual Strain in Welded Inconel 718 for NASA Space Shuttle Flow Liners  

NASA Astrophysics Data System (ADS)

This work quantitatively assesses residual strains and stresses associated with the weld repair process used to repair cracks on NASA's space shuttle flow liners. The coupons used in this investigation were made of the same INCONEL 718 alloy used for the flow liners. They were subjected to identical welding and certification procedures that were carried out on the space shuttle. Neutron diffraction measurements at Los Alamos National Laboratory determined residual strains at selected locations in a welded coupon at 293 K and 135 K. The weld repair process introduced Mises effective residual stresses of up to 555 MPa. On comparing the measurements at 293 K and 135 K, no significant change to the residual strain profile was noted at the low temperature. This indicated minimal mismatch in the coefficients of thermal expansion between the base metal and the weld.

Structural analysis of a frangible nut used on the NASA Space Shuttle  

SciTech Connect

A structural analysis methodology has been developed for the NASA 2.5-inch frangible nut used on the Space Shuttle. Two of these nuts are used to secure the External Tank to the aft end of the Orbiter. Both nuts must completely fracture before the Orbiter can safely separate from the External Tank. Ideally, only one of the two explosive boosters contained in each nut must detonate to completely break a nut. However, after an uncontrolled change in the Inconel 718 material processing, recent tests indicate that in certain circumstances both boosters may be required. This report details the material characterization and subsequent structural analyses of nuts manufactured from two lots of Inconel 718. The nuts from the HSX lot were observed to consistently separate with only one booster, while the nuts from the HBT lot never completely fracture with a single booster. The material characterization requires only tensile test data and the determination of a tearing parameter based on a computer simulation of a tensile test. Subsequent structural analyses using the PRONTO2D finite element code correctly predict the differing response of nuts fabricated from these two lots. This agreement is important because it demonstrates that this technique can be used to screen lots of Inconel 718 before manufacturing frangible nuts from them. To put this new capability to practice, Sandia personnel have transferred this technology to the Pyrotechnics Group at NASA-JSC.

Simulation of Shuttle launch G forces and acoustic loads using the NASA Ames Research Center 20G centrifuge  

NASA Astrophysics Data System (ADS)

The high cost and long times required to develop research packages for space flight can often be offset by using ground test techniques. This paper describes a space shuttle launch and reentry simulating using the NASA Ames Research Center's 20G centrifuge facility. The combined G-forces and acoustic environment during shuttle launch and landing were simulated to evaluate the effect on a payload of laboratory rates. The launch G force and acoustic profiles are matched to actual shuttle launch data to produce the required G-forces and acoustic spectrum in the centrifuge test cab where the rats were caged on a free-swinging platform. For reentry, only G force is simulated as the aero-acoustic noise is insignificant compared to that during launch. The shuttle G-force profiles of launch and landing are achieved by programming the centrifuge drive computer to continuously adjust centrifuge rotational speed to obtain the correct launch and landing G forces. The shuttle launch acoustic environment is simulated using a high-power, low-frequency audio system. Accelerometer data from STS-56 and microphone data from STS-1 through STS-5 are used as baselines for the simulations. This paper provides a description of the test setup and the results of the simulation with recommendations for follow-on simulations.

Shared visions: Partnership of Rockwell International and NASA Cost Effectiveness Enhancements (CEE) for the space shuttle system integration program  

NASA Astrophysics Data System (ADS)

As a result of limited resources and tight fiscal constraints over the past several years, the defense and aerospace industries have experienced a downturn in business activity. The impact of fewer contracts being awarded has placed a greater emphasis for effectiveness and efficiency on industry contractors. It is clear that a reallocation of resources is required for America to continue to lead the world in space and technology. The key to technological and economic survival is the transforming of existing programs, such as the Space Shuttle Program, into more cost efficient programs so as to divert the savings to other NASA programs. The partnership between Rockwell International and NASA and their joint improvement efforts that resulted in significant streamlining and cost reduction measures to Rockwell International Space System Division's work on the Space Shuttle System Integration Contract is described. This work was a result of an established Cost Effectiveness Enhancement (CEE) Team formed initially in Fiscal Year 1991, and more recently expanded to a larger scale CEE Initiative in 1992. By working closely with the customer in agreeing to contract content, obtaining management endorsement and commitment, and involving the employees in total quality management (TQM) and continuous improvement 'teams,' the initial annual cost reduction target was exceeded significantly. The CEE Initiative helped reduce the cost of the Shuttle Systems Integration contract while establishing a stronger program based upon customer needs, teamwork, quality enhancements, and cost effectiveness. This was accomplished by systematically analyzing, challenging, and changing the established processes, practices, and systems. This examination, in nature, was work intensive due to the depth and breadth of the activity. The CEE Initiative has provided opportunities to make a difference in the way Rockwell and NASA work together - to update the methods and processes of the organizations. The future success of NASA space programs and Rockwell hinges upon the ability to adopt new, more efficient and effective work processes. Efficiency, proficiency, cost effectiveness, and teamwork are a necessity for economic survival. Continuous improvement initiatives like the CEE are, and will continue to be, vehicles by which the road can be traveled with a vision to the future.

A summary of the Space Shuttle Columbia tragedy and the use of digital high-speed photography in the accident investigation and NASA's return-to-flight effort  

NASA Astrophysics Data System (ADS)

On February 1, 2003, the Space Shuttle Columbia broke apart during reentry resulting in loss of seven crewmembers and craft. For the next several months an extensive investigation of the accident ensued involving a nationwide team of experts from NASA, industry, and academia, spanning dozens of technical disciplines. The Columbia Accident Investigation Board (CAIB), a group of experts assembled to conduct an investigation independent of NASA concluded in August, 2003 that the cause of the loss of Columbia and its crew was a breach in the left wing leading edge Reinforced Carbon-Carbon (RCC) thermal protection system initiated by the impact of thermal insulating foam that had separated from the orbiters external fuel tank 81 seconds into that mission's launch. During reentry, this breach allowed superheated air to penetrate behind the leading edge and erode the aluminum structure of the left wing which ultimately led to the breakup of the orbiter. Supporting the findings of the CAIB, were numerous ballistic impact testing programs conducted to investigate and quantify the physics of External Tank Foam impact on the RCC wing leading edge material. These tests ranged from fundamental material characterization tests to full-scale Orbiter Wing Leading Edge tests. Following the accident investigation, NASA turned its focus to returning the Shuttle safely to flight. Supporting this effort are many test programs to evaluate impact threats from various debris sources during ascent that must be completed for certifying the Shuttle system safe for flight. Digital high-speed cameras were used extensively to document these tests as significant advances in recent years have nearly eliminated the use of film in many areas of testing. Researchers at the NASA Glenn Ballistic Impact Laboratory have participated in several of the impact test programs supporting the Accident Investigation and Return-to-Flight efforts. This paper summarizes the Columbia Accident and the nearly seven month long investigation that followed. Highlights of the NASA Glenn contributions to the impact testing are presented with emphasis on the use of high speed digital photography to document theses tests.

Space Shuttle: The Next Generation  

NSDL National Science Digital Library

In a May 2003 online feature of Popular Science magazine, several potential candidates for replacing NASA's aging space shuttles are examined. Although budget problems have made the outlook somewhat bleak for any new designs in the near future, a number of existing proposals are outlined. An especially eye-catching concept is an enormous flying wing, which would climb to 40,000 feet and serve as a launching pad for a rocket. Another possibility, which would be an intermediate step before the full-fledged shuttle replacement, is the Orbital Space Plane. This would likely be less complex than the shuttle while serving as a manned or unmanned taxi to space. The five-page article also describes NASA's changing needs and how the shuttle no longer meets them.

New shuttle schedule released  

NASA Astrophysics Data System (ADS)

The Hubble Space Telescope has a tentative launch date of November 17, 1988, according to an announcement made October 3, 1986, by the National Aeronautics and Space Administration (NASA). The plan calls for the first shuttle launch to take place on February 18, 1988, when Discovery is slated to launch a second Tracking and Data Relay Satellite (TDRS). A TDRS satellite was aboard Challenger when it exploded on January 28, 1986.The $1.3 billion telescope would be launched aboard the fifth shuttle mission in 1988. After launching the TDRS satellite, NASA plans to send Atlantis and then Columbia spacebound with military payloads. In September 1988, Discovery would be launched again with a third TDRS satellite.

Shuttle Rocket Motor Program: NASA should delay awarding some construction contracts. Report to the Chair, Subcommittee on Government Activities and Transportation, Committee on Government Operations, House of Representatives  

NASA Astrophysics Data System (ADS)

Even though the executive branch has proposed terminating the Advanced Solid Rocket Motor (ASRM) program, NASA is proceeding with all construction activity planned for FY 1992 to avoid schedule slippage if the program is reinstated by Congress. However, NASA could delay some construction activities for at least a few months without affecting the current launch data schedule. For example, NASA could delay Yellow Creek's motor storage and dock projects, Stennis' dock project, and Kennedy's rotation processing and surge facility and dock projects. Starting all construction activities as originally planned could result in unnecessarily incurring additional costs and termination liability if the funding for FY 1993 is not provided. If Congress decides to continue the program, construction could still be completed in time to avoid schedule slippage.

Shuttle accident stalls science plans  

NASA Astrophysics Data System (ADS)

Plans to make 1986 a uniquely productive year for U.S. space science activities ended in one horrible moment with the January 28, 1986, explosion of the space shuttle Challenger. The joyless scene at Cape Canaveral, Fla., stood in sharp contrast to the overwhelming success of Voyager 2 in its encounter with Uranus 4 days earlier. (Scientific details of that encounter will follow in upcoming issues of Eos.)Of the 15 space shuttle flights planned for fiscal year 1986, beginning October 1, 1985, a total of seven were to have carried scientific payloads for the National Aeronautics and Space Administration (NASA). The remaining eight flights were evenly divided between missions for the U.S. Department of Defense and commercial missions for NASA's paying customers. The explosion caused NASA to put its entire space shuttle program on hold to allow time for engineers to find the cause of the accident and for NASA to implement corrective measures. As Eos went to press, NASA acting administrator William R. Graham had not yet released the names of those who would serve on the formal investigative panel. “I think everybody's agreed that it will take weeks to months to unravel,” said Alexander Dessler, director of the space science laboratory at NASA's Marshall Space Flight Center near Huntsville, Ala. Dessler speculated that investigators would begin with a list of hundreds of possible causes for the explosion.

Diary of an astronaut: examination of the remains of the late Israeli astronaut Colonel Ilan Ramon's Crew Notebook recovered after the loss of NASA's space shuttle Columbia.  

PubMed

Two months after the fatal re-entering into the Earth's atmosphere of Columbia flight STS-107, the remains of Israeli astronaut Colonel Ilan Ramon's Crew Notebook were found strewn in a field in San Augustine County, TX. The random pile of papers was found to have survived the calamity of the Shuttle's disintegration remarkably well. Most of the papers recovered were torn and/or washed out to varying degrees but only mildly charred around the edges. The sheets of paper could be categorized into four groups: Group I: eight sides of paper written while in space in black ink and in pencil--Ramon's personal diary; the writing on these eight sides of paper survived well and is only missing where the pages were torn. Small fragments found in the field were physically matched to holes in the pages thus locating their original positions in the text. Group II: six sides of technical preparation notes written by Ramon before the mission. The writing on these pages was washed out entirely, but much of it was visualized using infrared luminescence. Group III: eight sides of personal notes prepared by Ramon before the mission written in blue ink. The writing on these pages was barely visible to the naked eye and not visualized by infrared luminescence, but was made largely legible by digital enhancement imaging. Group IV: a few sides of printed technical information. These pages were mostly intact and were not examined at length as they contained standard printed material. After completion of examinations at the Questioned Document Laboratory of the Israel Police, the diary was transferred to the Paper Conservation Department of the Israel Museum for preservation and strengthening treatments.

Liquid lift for the Shuttle  

NASA Astrophysics Data System (ADS)

After the operational failure of a Solid Rocket Booster (SRB) led to the Space Shuttle Challenger accident, NASA reexamined the use of liquid-fueled units in place of the SRBs in order to ascertain whether they could improve safety and payload. In view of favorable study results obtained, the posibility has arisen of employing a common liquid rocket booster for the Space Shuttle, its cargo version ('Shuttle-C'), and the next-generation Advanced Launch System. The system envisioned would involve two booster units, whose four engines/unit would be fed by integral LOX and kerosene tanks. Mission aborts with one-booster unit and two-unit failures would not be catastrophic, and would respectively allow LEO or an emergency landing in Africa.

Following the Space Shuttle Challenger accident, serious attention has turned to in-flight escape. Prior to the resumption of flight, a manual bailout system was qualified and installed. For the long term, a seated extraction system to expand the escape envelope is being investigated. This paper describes a 1987 study, conducted jointly by NASA/Johnson Space Center and Langley Research Center, to determine the feasibility of modifying the Space Shuttle Orbiters to incorporate the seated extraction system. Results of the study are positive, indicating retrofit opportunity and high probability of escape for early ascent, late entry, and even for uncontrolled flight such as the Challenger breakup. The system, as envisioned, can extract seven crewmembers within two seconds.

On February 1, 2003, the NASA space shuttle Columbia broke apart during re-entry over East Texas at an altitude of 200,000 feet and a velocity of approximately 12,000 mph. All aboard perished. Prof. Osheroff was a member of the board that investigated the origins of this accident, both physical and organizational. In his talk he will describe how the board was able to determine with almost absolute certainty the physical cause of the accident. In addition, Prof. Osherhoff will discuss its organizational and cultural causes, which are rooted deep in the culture of the human spaceflight program. Why did NASA continue to fly the shuttle system despite the persistent failure of a vital sub-system that it should have known did indeed pose a safety risk on every flight? Finally, Prof. Osherhoff will touch on the future role humans are likely to play in the exploration of space.

Infrared spectral measurement of space shuttle glow  

SciTech Connect

Infrared spectral measurements of the space shuttle glow were successfully conducted during the STS-39 space shuttle mission. Analysis indicates that NO, NO[sup +], OH, and CO are among the molecules associated with the infrared glow phenomenon. During orbiter thruster firings the glow intensities in the infrared are enhanced by factors of 10x to 100x with significant changes in spectral distribution. These measurements were obtained with the Spacecraft Kinetic Infrared Test (SKIRT) payload which included a cryogenic infrared circular variable filter (CVF) spectrometer (0.6 [mu]m to 5.4 [mu]) and a number of infrared, visible, and ultraviolet radiometers (0.2 [mu]m to 5.4 [mu]m and 9.9 [mu]m to 10.4 [mu]m). In addition, glow measurements were unsuccessfully attempted with the Cryogenic Infrared Radiance Instrumentation for Shuttle (CIRRIS-1A) with its 2.5 [mu]m to 25 [mu]m Fourier transform interferometer. SKIRT CVF obtained over 14,000 spectra of quiescent shuttle glow, thruster enhanced shuttle glow, upper atmosphere airglow, aurora, orbiter environment, and deep space non-glow backgrounds during its eight day mission. The SKIRT radiometers operated almost continuously throughout the mission to provide a detailed history of the IR/VIS/UV optical environment associated with the operation of large spacecraft structures in low earth orbit. This dissertation will primarily address those measurements conducted by the SKIRT spectrometer as they relate to space shuttle glow in the infrared. The STS-39 Space Shuttle Discovery was launched from the NASA Kennedy Space Center on 28 April 1991 into a 57 degree inclination circular orbit at an altitude of 260 km.

NASA World Wind allows one to zoom from satellite altitude into any place on Earth, leveraging the combination of high resolution LandSat imagery and SRTM elevation data to experience Earth in visually rich 3D, just as if they were really there. NASA World Wind combines LandSat 7 imagery with Shuttle Radar Topography Mission (SRTM) elevation data, for a dramatic view of the Earth at eye level. Users can literally fly across the world's terrain from any location in any direction. Particular focus was put into the ease of usability so people of all ages can enjoy World Wind. All one needs to control World Wind is a two button mouse. Additional guides and features can be accessed though a simplified menu. Navigation is automated with single clicks of a mouse as well as the ability to type in any location and automatically zoom to it. NASA World Wind was designed to run on recent PC hardware with the same technology used by today's 3D video games. NASA World Wind delivers the NASA Blue Marble, spectacular true-color imagery of the entire Earth at 1-kilometer-per-pixel. Using NASA World Wind, you can continue to zoom past Blue Marble resolution to seamlessly experience the extremely detailed mosaic of LandSat 7 data at an impressive 15-meters-per-pixel resolution. NASA World Wind also delivers other color bands such as the infrared spectrum. The NASA Scientific Visualization Studio at Goddard Space Flight Center (GSFC) has produced a set of visually intense animations that demonstrate a variety of subjects such as hurricane dynamics and seasonal changes across the globe. NASA World Wind takes these animations and plays them directly on the world. The NASA Moderate Resolution Imaging Spectroradiometer (MODIS) produces a set of time relevant planetary imagery that's updated every day. MODIS catalogs fires, floods, dust, smoke, storms and volcanic activity. NASA World Wind produces an easily customized view of this information and marks them directly on the globe. When one of these color coded markers are clicked, it downloads the full image and displays it in the full context of its location on Earth. MODIS images are publication quality material at resolutions up to 250-meters-per-pixel. NASA World Wind provides a full catalog of countries, capitals, counties, cities, towns, and even historical references. The names appear dynamically, increasing in number as the user zooms in. World Wind is capable of browsing through and displaying GLOBE data based on any date one wishes planetary data for. That means one can download today's (or any previous day's) temperature across the world, or rainfall, barometric pressure, cloud cover, or even the GLOBE students' global distribution of collected data. This program is free and available for further development via the NASA Open Source Agreement guidelines.

A review is provided of four basic programs which have to be satisfied. Aspects of science and technology transfer are discussed. The restrictions for the transfer of science and technology information are covered under various NASA Management Instructions (NMI's). There were two major events which influenced the protection of sensitive and private information on the Space Shuttle program. The first event was a manned space flight accident, while the second was the enactment of a congressional bill to establish the rights of privacy. Attention is also given to national resource protection and national defense classified operations.

Various systems failures including Space Shuttle main engine failures and detailed technical analyses, including the design of powered flight abort trajectories, are considered. The most critical of flight abort situations is the RTLS, while TAL is the preferred abort when uphill capability is no longer available. It is concluded that one principle must remain to ensure continuing success of Space Shuttle flights: namely that intact and contingency aborts necessitate development to ensure safe return of the vehicle, payload, and crew whenever possible.

As NASA gears up for another attempt at redesigning Space Station Freedom, some in Congress are wondering whether the space agency has learned any lessons from a number of costly past mistakes. Louis Stokes (D-Ohio), the new chairman of the House Appropriations Veterans Affairs, Housing and Urban Development, and Independent Agencies Subcommittee, held a hearing on March 17 to examine unanticipated cost growth in a variety of projects, including the space toilet, the advanced turbo pump for the shuttle, and the Mars Observer, as well as the space station. Stokes seemed well-suited to this oversight role, asking well-informed and probing questions rather than accusatory ones. The witnesses, NASA head Daniel Goldin and many of his top managers (most of whom were not in their present positions when the projects were initiated), analyzed past errors and offered useful measures for avoiding similar problems in the future.

Expendable launch vehicles in Space Station Freedom logistics resupply operations

The projected Space Station Freedom (SSF) annual logistics resupply requirements were predicted to exceed the 1988 baseline Shuttle resupply system capability. This paper examines the implications of employing a 'mixed fleet' of Shuttles and ELVs to provide postassembly, steady-state logistics resupply. The study concluded that ELVs supported by the OMV could provide the additional required resupply capability with one to three launches per annum. However, the study determined that such a capability would require significant programmatic commitments, including baseline SSF OMV accommodations, on-orbit OMV monoprop replenishment capability, and substantial economics investments. The study also found the need for a half-size pressurized logistics module for the increase in the efficiency of logistics manifesting on the Shuttle as well as ELVs.

MICROBIOLOGY: Malaria's Stealth Shuttle  

NSDL National Science Digital Library

Access to the article is free, however registration and sign-in are required. Sturm et al. report a major twist to this story during the liver stage of malaria infection. Using Plasmodium berghei, a mouse model of malaria, they show that the liver-stage parasite keeps its host hepatocyte alive long enough to complete development but allows it to then commit an unusual form of suicide that helps the parasite evade host defenses and deposit new invasive forms into the bloodstream. Membranous vesicles shuttle malaria parasites from liver to blood cells during infection, ensuring protection against the host's defenses.

Projections for Future Funding of NASA And NASA Science Activities: Reassessing the Obama FY 2010 Budget Request  

NASA Astrophysics Data System (ADS)

This paper develops a novel approach for predicting future funding for the total NASA budget and for science activities within that budget. Although the budget process is inherently political, it is adequately characterized by analyzing the last thirty-two years of NASA budgets, organized by the party of the President. Over the last thirty-two years, Republicans have increased the buying power of the NASA budget while Democrats have decreased it, with significant differences in the rates. The President's budget projections for NASA, available since 1990, are used to produce a model that may be applied to future budget projections. Before final conclusions are drawn from these results, the most significant NASA budgetary event of this decade is examined: the one billion dollar share of the American Recovery and Reinvestment Act of 2009. The hypothesis is that an unanticipated, significant, one-year increase to the NASA budget can affect NASA's funding profile for more than one year. This is tested with the only other similar event in NASA history, the unanticipated budget increase following the loss of Space Shuttle Challenger in 1986. An event study of the changes in NASA's total budget before and after the loss of Challenger indicates that the one-year spike in funding increased subsequent NASA growth rates for four years. These results are combined to predict future NASA top-level and science budgets for FY 2011 and FY 2012.

Satellite Observations of Space Shuttle Main Engine Exhaust: Vertical Diffusion and Meridional Transport  

NASA Astrophysics Data System (ADS)

The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) experiment on NASA’s Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite has observed water vapor radiances near 6.6 microns on the Earth’s limb since the TIMED launch in December, 2001. Following a space shuttle launch, SABER typically observes enhanced water vapor emission between 90-110 km altitude near the east coast of the United States, where the shuttle injects about 300 metric tons of water vapor exhaust from its three main engines. SABER has observed plumes from 20 space shuttle launches since 2002, all within 25 hours of injection. The database of observations now consists of over 80 separate plume scans, each of which is identified with a peak altitude, a peak brightness and a plume thickness. We compare these SABER shuttle plume observations with a two-dimensional diffusion model that includes photodissociation to determine whether the time evolution of the plume altitude and thickness can be reproduced. Some observations indicate that the shuttle plume is subject to rapid meridional transport. We compare the inferred meridional motion of the plumes with a satellite-derived wind climatology. We include the effects of tidal variability on the shuttle plume and determine whether there is a time of year during which the wind climatology better explains the observed meridional transport.

Environmental monitoring instrumentation and monitoring techniques for space shuttle launches. Final report, Jan 82-Jul 83  

SciTech Connect

The Space Shuttle emits undesired exhaust materials into the atmosphere during a launch including large quantities of hydrogen chloride (HCl). The fate of the HCl is not well understood but includes deposition and HCl gas revolatilization near the launch pad and downwind acid washout, acid rainout and HCl gas dispersion. The Air Force and NASA began monitoring missile exhaust effluents in the early 1970s. There has been an evolution in monitoring instrumentation, monitoring techniques and monitoring schemes developed jointly by the Air Force and NASA culminating in the efforts for Space Shuttle launches at Kennedy Space Center. This report reviews and evaluates these efforts and recommends an integrated program of ground monitors, aircraft monitors and remote sensors to monitor shuttle exhaust materials.

Transport logistics in pollen tubes.  

PubMed

Cellular organelles move within the cellular volume and the effect of the resulting drag forces on the liquid causes bulk movement in the cytosol. The movement of both organelles and cytosol leads to an overall motion pattern called cytoplasmic streaming or cyclosis. This streaming enables the active and passive transport of molecules and organelles between cellular compartments. Furthermore, the fusion and budding of vesicles with and from the plasma membrane (exo/endocytosis) allow for transport of material between the inside and the outside of the cell. In the pollen tube, cytoplasmic streaming and exo/endocytosis are very active and fulfill several different functions. In this review, we focus on the logistics of intracellular motion and transport processes as well as their biophysical underpinnings. We discuss various modeling attempts that have been performed to understand both long-distance shuttling and short-distance targeting of organelles. We show how the combination of mechanical and mathematical modeling with cell biological approaches has contributed to our understanding of intracellular transport logistics. PMID:23686949

Space Shuttle: Declining budget and tight schedule could jeopardize space station support. Report to the Chairman, Subcommittee on Oversight of Government Management and the District of Columbia, Committee on Governmental Affairs, US Senate  

NASA Astrophysics Data System (ADS)

NASA plans to use the space shuttle on 21 flights over a 5-year period to assemble the International Space Station. To meet this requirement, the shuttle will have to undergo substantial redesign to gain additional lift capability. The General Accounting Office (GAO) has examined the extent to which the shuttle program can support the the space station's assembly requirements. The impacts of a declining shuttle budget and a demanding schedule to support the space station were examined. GAO made recommendations that the Administrator of NASA establish an independent review team to (1) assess NASA's systems integration plan for the lift-increasing enhancements, (2) identify the associated technical and programmatic risks, and (3) weigh the costs and benefits of NASA's tight scheduling of shuttle flights to assemble the space station. The findings are (1) that some of the hardware redesign programs have experienced early development problems, and the potential exists for additional problems; (2) NASA's schedule for meeting the space station's launch requirements appears questionable, and (3) the shuttle's modification and launch enhancement program includes plans to defer some recertification activities and forgo full integration testing of the propulsion system. Given the magnitude and complexity of the shuttle enhancement program, GAO believes it is prudent to take additional measures to ensure that (1) the implications of integrating numerous individual design changes are fully understood and (2) safety is not compromised.

Processing ground-based near-infrared imagery of space shuttle re-entries  

NASA Astrophysics Data System (ADS)

Ground-based high-resolution, calibrated, near-infrared (NIR) imagery of the Space Shuttle STS-134 Endeavour during reentry has been obtained as part of NASA's HYTHIRM (Hypersonic Thermodynamic InfraRed Measurements) project. The long-range optical sensor package called MARS (Mobile Aerospace Reconnaissance System) was positioned in advance to acquire and track part of the shuttle re-entry. Imagery was acquired during a few minutes, with the best imagery being processed when the shuttle was at 133 kft at Mach 5.8. This paper describes the processing of the NIR imagery, building upon earlier work from the airborne imagery collections of several prior shuttle missions. Our goal is to calculate the temperature distribution of the shuttle's bottom surface as accurately as possible, considering both random and systematic errors, while maintaining all physical features in the imagery, especially local intensity variations. The processing areas described are: 1) radiometric calibration, 2) improvement of image quality, 3) atmospheric compensation, and 4) conversion to temperature. The computed temperature image will be shown, as well as comparisons with thermocouples at different positions on the shuttle. A discussion of the uncertainties of the temperature estimates using the NIR imagery is also given.

3D inspection for the Shuttle return to flight  

NASA Astrophysics Data System (ADS)

NASA contracted Neptec to provide the Laser Camera System (LCS), a 3D scanning laser sensor, for the on-orbit inspection of the Space Shuttle's Thermal Protection System (TPS) on the return-to-flight mission STS-114. The scanner was mounted on the boom extension to the Shuttle Remote Manipulator System (SRMS). Neptec's LCS was selected due to its close-range accuracy, large scanning volume and immunity to the harsh ambient lighting of space. The crew of STS-114 successfully used the LCS to inspect and measure damage to the Discovery Shuttle TPS in July, 2005. The crew also inspected the external-tank (ET) doors to ensure that they were fully closed. Neptec staff also performed operational support and real-time detailed analysis of the scanned features using analysis workstations at Mission Control Center (MCC) in Houston. This paper provides a summary of the on-orbit scanning activities and a description of the results detailed in the analysis.

The Space Shuttle and expendable launch systems - A U.S. commercial customer perspective  

NASA Astrophysics Data System (ADS)

The development of space transportation systems for commercial satellite launches is reviewed. A comparison of the Ariane system with the Space Shuttle is presented. The performance capability, reliability, and availability of the two systems are analyzed; the Ariane 4 is capable of launching payloads of 1900-4200 kg into transfer orbits and is better positioned than the Shuttle to handle commercial payloads greater than 1900 kg. The insurance costs, and spacecraft and launcher integration complexity for the two systems are discussed. The launch cost and postponement penalties are studied. NASA's launch cost is based on the length or mass of the payload multiplied by the fixed Shuttle cost, with Ariane attempting to keep prices $1-3 million lower, in order to be competitive with the Shuttle. NASA offers one free postponement and penalties as high as 55 percent; Ariane's penalties range from 6-18 percent of the launch price. The need for lower prices, an easier integration process, customer convience, and less severe postponement and reflight policies in order for the space transportation systems to be commercially useful, is discussed.

The new discipline of astrobiology addresses fundamental questions about life in the universe: "Where did we come from?" "Are we alone in the universe?" "What is our future beyond the Earth?" Developing capabilities in biotechnology, informatics, and space exploration provide new tools to address these old questions. The U.S. National Aeronautics and Space Administration (NASA) has encouraged this new discipline by organizing workshops and technical meetings, establishing a NASA Astrobiology Institute, providing research funds to individual investigators, ensuring that astrobiology goals are incorporated in NASA flight missions, and initiating a program of public outreach and education. Much of the initial effort by NASA and the research community was focused on determining the technical content of astrobiology. This paper discusses the initial answer to the question "What is astrobiology?" as described in the NASA Astrobiology Roadmap. PMID:12448992

A Containment Vault for a Shuttle Return of a MARS Sample  

NASA Astrophysics Data System (ADS)

In a relatively short period of time, roughly 12 weeks, the Advanced Design Team at the Johnson Space Center (JSC), developed and analyzed a set of requirements and proposed a design for a Mars sample return scenario, utilizing a Shuttle return for the final leg of the journey. This design was a part of a larger sample return architecture being proposed by JSC. The requirements, combined with a probability risk assessment (PRA) done by Science Applications International Corporation (SAIC), were used to create a design for a shuttle-based vault for holding a sample container, mounted on a spacecraft, which has returned from Mars. This Vault was designed to try and attain containment assurance of the sample to 1 in a million, when leveraged with the Shuttle's worst-case probability of failure. The resulting design was therefore contingent upon having an accurate understanding of Shuttle failures and crash scenarios. The study has produced a high- level design for a possible Vault, housed in the Shuttle, which stands very close to meeting the difficult containment assurance requirement for planetary protection (per the NASA Planetary Protection Officer).

The U.S. and NASA currently use a diverse, flexible family of ETO (Earth To Orbit) launch systems. One element of this family is the expendable launch vehicles. For this element, NASA procures the requisite launch services directly from the commercial sector. The major current U.S. vehicles in this segment are Delta, Atlas, and Titan. The characteristics of these vehicles and rocket propulsion are described. The other element of the current launcher family is the Space Shuttle fleet. The Shuttle propulsion elements, including the Space Shuttle Main Engine (SSME), the Main Propulsion System (MPS), the External Tank (ET), and the Solid Rocket Booster (SRB), are described. Looking ahead, new launch vehicles featuring increased mission safety and reliability, reduced operations requirements and costs and enhanced performance are projected. The elements of these systems would support a modular approach capable of transporting a range of payload. The rocket propulsion elements under consideration for these vehicles, including the Space Transportation Main Engine (STME), propulsion modules, a modified STS external tank and solid rocket motors, are described.

The NASA Standard Detonator (NSD) is employed in support of a number of current applications, including the Space Shuttle. This effort was directed towards providing test results to characterize the output of this device for its use in a safe and arm device. As part of the investigation, flash X-ray was used to provide stop-motion photographs of the flying metal plate that is created by initiation of the detonator. This provided researchers with a better understanding of the shape and character of the high-velocity disk as it propagated across the gap between the detonator and next assembly. The second portion of the study used a velocity interferometer to evaluate the acceleration and velocity histories of the flying plate, providing a quantified assessment of the detonator`s ability to initiate the explosive in the next explosive.

Technology development: Future use of NASA's large format camera is uncertain  

NASA Astrophysics Data System (ADS)

The Large Format Camera, developed as a project to verify an engineering concept or design, has been flown only once, in 1984, on the shuttle Challenger. Since this flight, the camera has been in storage. NASA had expected that, following the camera's successful demonstration, other government agencies or private companies with special interests in photographic applications would absorb the costs for further flights using the Large Format Camera. But, because shuttle transportation costs for the Large Format Camera were estimated to be approximately $20 million (in 1987 dollars) per flight and the market for selling Large Format Camera products was limited, NASA was not successful in interesting other agencies or private companies in paying the costs. Using the camera on the space station does not appear to be a realistic alternative. Using the camera aboard NASA's Earth Resources Research (ER-2) aircraft may be feasible. Until the final disposition of the camera is decided, NASA has taken actions to protect it from environmental deterioration. The Government Accounting Office (GAO) recommends that the NASA Administrator should consider, first, using the camera on an aircraft such as the ER-2. NASA plans to solicit the private sector for expressions of interest in such use of the camera, at no cost to the government, and will be guided by the private sector response. Second, GAO recommends that if aircraft use is determined to be infeasible, NASA should consider transferring the camera to a museum, such as the National Air and Space Museum.

Seismic excitation by space shuttles  

USGS Publications Warehouse

Shock waves generated by the space shuttles Columbia (August 13, 1989), Atlantis (April 11, 1991) and Discovery (September 18, 1991) on their return to Edwards Air Force Base, California, were recorded by TERRAscope (Caltech's broadband seismic network), the Caltech-U.S.G.S Southern California Seismic Network (SCSN), and the University of Southern California (USC) Los Angeles Basin Seismic Network. The spatial pattern of the arrival times exhibits hyperbolic shock fronts from which the path, velocity and altitude of the space shuttle could be determined. The shock wave was acoustically coupled to the ground, converted to a seismic wave, and recorded clearly at the broadband TERRAscope stations. The acoustic coupling occurred very differently depending on the conditions of the Earth's surface surrounding the station. For a seismic station located on hard bedrock, the shock wave (N wave) was clearly recorded with little distortion. Aside from the N wave, very little acoustic coupling of the shock wave energy to the ground occurred at these sites. The observed N wave record was used to estimate the overpressure of the shock wave accurately; a pressure change of 0.5 to 2.2 mbars was obtained. For a seismic station located close to the ocean or soft sedimentary basins, a significant amount of shock wave energy was transferred to the ground through acoustic coupling of the shock wave and the oceanic Rayleigh wave. A distinct topography such as a mountain range was found effective to couple the shock wave energy to the ground. Shock wave energy was also coupled to the ground very effectively through large man made structures such as high rise buildings and offshore oil drilling platforms. For the space shuttle Columbia, in particular, a distinct pulse having a period of about 2 to 3 seconds was observed, 12.5 s before the shock wave, with a broadband seismograph in Pasadena. This pulse was probably excited by the high rise buildings in downtown Los Angeles which were simultaneously hit by the space shuttle shock waves. The proximity of the natural periods of the high rise buildings and the modal periods of the Los Angeles basin enabled efficient energy transfer from shock wave to seismic wave. ?? 1992 Springer-Verlag.

Academic science and NASA  

NASA Astrophysics Data System (ADS)

The fiscal 1984 budget of the National Aeronautics and Space Administration (NASA) contains some pleasant surprises. The new budget reflects, in some areas, a welcome change from the recent emphasis toward earth-orbiting of space missions of limited scientific content. (For the overall fiscal 1984 NASA budget, see Eos, October 4, 1983, p. 577.)The July 1983 NASA in-house study-group report titled “The Universities and NASA Space Sciences” emphasizes that the past decade's decreasing budgets have resulted in a severe lessening of university capabilities in space science. Smaller budgets have meant significantly fewer start-ups of space missions with scientific emphasis. Meanwhile, data analysis from continuing and completed missions has not been well funded.

NASA's ESDS Reference Architecture  

NASA Astrophysics Data System (ADS)

Over the last few decades, advances in geophysical measurement technologies have led to an explosion in the volume and scope of Earth Science data sets. Implementation of the instrument systems that acquire these measurements requires commensurate development in data systems to enable the collection, processing, archiving and distribution of the resultant large volumes of data. As more and more of the data systems come on line, their common features have become increasingly apparent. NASA's Earth Science Data System Working Group (ESDSWG) recognizes these trends and needs and has asked its Standards Process Group (SPG) to develop a reference architecture for NASA's Earth Science Data Systems (ESDS's). That reference architecture is introduced in this presentation. The NASA ESDS Reference Architecture describes those common features and patterns, and thus provides guidelines for individuals and teams who plan to construct and interact with new NASA ESDS's.

Human interactions in space: ISS vs. Shuttle/Mir  

NASA Astrophysics Data System (ADS)

This paper compares findings from two NASA-funded studies of international long-duration missions to the Mir space station (Shuttle/Mir) and to the International Space Station (ISS). American and Russian crewmembers and mission control personnel participated. Issues examined included changes in mood and group social climate over time, displacement of group tension to outside monitoring personnel, cultural differences, and leadership roles. Findings were based on the completion of a weekly questionnaire that included items from the Profile of Mood States, the Group Environment Scale, and the Work Environment Scale. An examination of issues investigated in both studies revealed much similarity in findings. There was little support for the presence of changes in levels of mood and group climate over time, and no evidence for a “3rd quarter phenomenon”. Both studies also provided evidence for the displacement of negative emotions to outside personnel in both crewmembers and mission control personnel. There were similar patterns of differences between Americans and Russians and between crewmembers and mission control personnel. Finally, in both studies, the support role of the leader was related to group cohesion among crewmembers, and both the task and support roles of the leader were related to cohesion among mission control personnel. Thus, in these four areas, the ISS study substantially replicated the findings from the earlier Shuttle/Mir study, suggesting that common psychosocial issues affect people engaged in on-orbit space missions.

Shuttle radar topography mapper (SRTM)  

NASA Astrophysics Data System (ADS)

The use of interferometric SAR (IFSAR) to measure elevation is one of the most powerful and promising capabilities of radar. A properly equipped spaceborne IFSAR system can produce a highly accurate global digital elevation map, including cloud-covered areas, in significantly less time and at significantly lower cost than with other systems. For accurate topography, the interferometric measurements must be performed simultaneously in physically sperate receive system, since measurements made at different times with the same system suffer significant decorrelation. The US/German/Italian spaceborne imaging radar C/X-band SAR (SIR-C/X-SAR), successfully flown twice in 1994 aboard the Space Shuttle Endeavor, offers a unique opportunity for global multifrequency elevation mapping by the year 2000. With appropriate augmentation, SIR-C/X-SAR is capable of producing an accurate elevation map covering 80 percent of the Earth's land surface in a single 10-day Shuttle flight. The existing US SIR-C SCANSAR mode provides a 225-km swath at C-band, which makes this coverage possible. Addition of a C-band receive antenna, extended from the Shuttle bay on a mast and operating in concert with the existing SIR-C antenna, produces an interferometric pair. Accuracy is enhanced by utilizing the SIR-C dual polarizations simultaneously to form separate SCANSAR beams. Due to the practical limitation of approximately 60 meters for the mast length, the longer SIR-C L-band wavelength does not produce useful elevation measurement accuracy. IFSAR measurements can also be obtained by the German/Italian X-SAR, simultaneously with SIR-C, by utilizing an added outboard antenna at X-band to produce a swath coverage of about 50 km. Accuracy can be enhanced at both frequencies by processing both ascending and descending data takes. It is estimated that the 90 percent linear absolute elevation error achievable is less that 16 meters for elevation postings of 30 meters. This will be the first use of spaceborne IFSAR to acquire accurate topographic data on a global scale.

A study of the radiation environment on board the space shuttle flight STS-57  

NASA Astrophysics Data System (ADS)

A joint NASA-Russian study of the radiation environment inside a SPACEHAB 2 locker on space shuttle flight STS-57 was conducted. The shuttle flew in a nearly circular orbit of 28.5 deg inclination and 462 km altitude. The locker carried a charged particle spectrometer, a tissue equivalent proportional counter (TEPC), and two area passive detectors consisting of combined NASA plastic nuclear track detectors (PNTD's) and thermoluminescent detectors (TLD's), and Russian nuclear emulsions, PNTD's, and TLD's. All the detector systems were shielded by the same shuttle mass distribution. This makes possible a direct comparison of the various dose measurement techniques. In addition, measurements of the neutron energy spectrum were made using the proton recoil technique. The results show good agreement between the integral LET spectrum of the combined galactic and trapped particles using the tissue equivalent proportional counter and track detectors between about 15 keV/micron and 200 keV/micron. The LET spectrum determined from nuclear emulsions was systematically lower by about 50%, possibly due to emulsion fading. The results show that the TEPC measured an absorbed dose 20% higher than TLD's, due primarily to an increased TEPC response to neutrons and a low sensitivity of TLD's to high LET particles under normal processing techniques. There is a significant flux of high energy neutrons that is currently not taken into consideration in dose equivalent calculations. The results of the analysis of the spectrometer data will be reported separately.

Reviewing NASA research  

NASA Astrophysics Data System (ADS)

A recent report by NASA's Space and Earth Science Advisory Committee cautions against assigning the space agency's research and analysis efforts a lower priority than flight operations. If pre- and post-mission science continue to take a back seat to the actual building and launching of spacecraft, the report warns, it may eventually compromise NASA's ability to ensure U.S. leadership in space science.The report was written by a working group consisting of both NASA personnel and earth and space scientists from the academic community. The group was asked in May 1983 to examine the health of the research and analysis (R&A) program conducted by NASA's Office of Space Science and Applications (OSSA) in the earth and space sciences. While the group found that the quality of research management by scientists at NASA Headquarters was “impressive,” it also identified a critical shortage of cash for R&A programs. According to the report, “the immediate requirements involve an increase of about $10 million in each of the Astrophysics, Earth Science and Applications, and Solar System Exploration divisions, thereby establishing a new base funding level for these activities.”

Science on the Space Shuttle  

NASA Astrophysics Data System (ADS)

On the Space Shuttle's third flight, scientific instruments will study the electromagnetic environment with charging and electron beams. Beam plasma discharge will be studied. The plasma diagnostics package contains electromagnetic and particle sensors to study the ionosphere. An attempt will be made to establish a more accurate base of solar UV irradiance measurements with an absolute error of 10 percent or less over the wavelength region 120-400 nm. The solar flare X-ray polarimeter will observe flare X-rays emitted between 5 and 30 keV and measure their polarization as a function of time and photon energy. A photopolarimeter will help study zodiacal light, and interplanetary dust will be sampled by a section of thick aluminum foil. Plant seedlings will be grown to research the effect of near-zero gravity on lignification. A thermal canister experiment will help determine whether instruments can be maintained at a fixed temperature under varying thermal loads.

Optimal control for electron shuttling  

NASA Astrophysics Data System (ADS)

In this paper we apply an optimal control technique to derive control fields that transfer an electron between ends of a chain of donors or quantum dots. We formulate the transfer as an optimal steering problem, and then derive the dynamics of the optimal control. A numerical algorithm is developed to effectively generate control pulses. We apply this technique to transfer an electron between sites of a triple quantum dot and an ionized chain of phosphorus dopants in silicon. Using the optimal pulses for the spatial shuttling of phosphorus dopants, we then add hyperfine interactions to the Hamiltonian and show that a 500 G magnetic field will transfer the electron spatially as well as transferring the spin components of two of the four hyperfine states of the electron-nuclear spin pair.

Shuttle Radar Topography Mission - New Products in 2005  

USGS Publications Warehouse

In February 2000, the Shuttle Radar Topography Mission (SRTM) successfully collected Interferometric C-Band Synthetic Aperture Radar data over 80 percent of the Earth's land surface, for most of the area between 60?N and 56?S latitude. NASA and the National Geospatial-Intelligence Agency (NGA), formerly known as the National Imagery and Mapping Agency (NIMA), co-sponsored the mission. NASA's Jet Propulsion Laboratory (JPL) performed preliminary processing of SRTM data and forwarded partially finished data directly to NGA for finishing by NGA contractors and subsequent monthly deliveries to the NGA Digital Products Data Warehouse (DPDW). All data products delivered by the contractors conform to NGA SRTM Data Products and NGA Digital Terrain Elevation Data? (DTED?) specifications. The DPDW ingests the SRTM data products, checks them for formatting errors, loads the public SRTM DTED? into the NGA data distribution system, and ships them to the U.S. Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS). In addition to NGA's SRTM DTED? format, USGS EROS has reformatted the data into a non-proprietary, generic raster binary SRTM format that is readable by most remote sensing software packages. The SRTM format is also publicly available from USGS EROS.

Dynamics and control of the Shuttle based large antenna system during slewing maneuvers  

NASA Astrophysics Data System (ADS)

A relatively general formulation for studying dynamics of a large class of interconnected flexible and/or rigid bodies forming a chain type topology is developed. The problem is approached using the Lagrangian procedure with the generalized forces accounting for the environmental effects, damping and control. The flexible members are taken to be the Euler-Bernoulli beams with their bending and torsional deformations discretized using a series of admissible functions. As a particular case, the general formulation is applied to study complex dynamics of the SCOLE (Spacecraft Control Laboratory Experiment) system as proposed in the NASA's design challenge. The classical infinite time linear state feedback regulator utilizing the Shuttle's primary and vernier thrusters is designed to suppress the vibrations as well as control the Shuttle attitude motion. The results suggest that flexiblility of the mast during the prescribed slewing maneuver substantially induces the line-of-sight error if the Shuttle is uncontrolled. However, the proposed control strategy can damp both the vibrational motion of the mast and librational motion of the Shuttle to the specified acceptable limit within 5 s of the completion of the maneuver.

Utilization of Shuttle small payload accommodations in the DOD Space Test Program  

NASA Astrophysics Data System (ADS)

Over the past 27 years, the U.S. Air Force, as executive agent for the Department of Defense (DOD) Space Test Program, has flown approximately 325 space experiments for the Army, Navy, Air Force, and other DOD agencies. These experiments have made significant contributions to the improvement of military technology and operations. Flight of Space Test Program experiments has been carried out utilizing free flyer spacecraft, the Space Shuttle crew cabin, and the Space Shuttle cargo bay. This paper will concentrate on those experiments which have been flown by the NASA Space Shuttle small payload flight systems, e.g., GAS, uprated GAS (CAP), and Hitchhiker flight systems. Discussions of Space Test Program experiments flown by Space Shuttle small payloads flight systems will include the experiment objectives, the accommodations and services provided by the flight systems, experiment results, and lessons learned from the planning and conduct of the flight. Particular emphasis will be placed on those experiments which required and were provided with a new and unique capability by the small payloads flight systems. These capabilities include the first use of the GAS opening lid, the first use of the GAS payload ejection capability, and the first use of the Hitchhiker cross bay carrier.

The NASA Balloon Program has made numerous accomplishments in 2008 and 2009. The successful completion of several heavy lift missions launched in the United States, Antarctica, and Sweden has provided science with unparalleled opportunities for observations that would otherwise have not been possible. Economic uncertainty makes ballooning a highly attractive alternative to higher cost orbital and suborbital missions, many of which have longer lead times. NASA's near space balloon capability offers experimenters today the ability to quickly place instruments into observational environments. This paper discusses current and future capabilities and rough order magnitude costs and lead times compared against other methods for achieving observational science.

Quantum Mechanical Models Of The Fermi Shuttle  

SciTech Connect

The Fermi shuttle is a mechanism in which high energy electrons are produced in an atomic collision by multiple collisions with a target and a projectile atom. It is normally explained purely classically in terms of the electron's orbits prescribed in the collision. Common calculations to predict the Fermi shuttle use semi-classical methods, but these methods still rely on classical orbits. In reality such collisions belong to the realm of quantum mechanics, however. In this paper we discuss several purely quantum mechanical calculations which can produce the Fermi shuttle. Being quantum mechanical in nature, these calculations produce these features by wave interference, rather than by classical orbits.

NASA Astrophysics Data System (ADS)

The NASA Exoplanet Archive is an online service that compiles and correlates astronomical information on extra solar planets and their host stars. The data in the archive include exoplanet parameters (such as orbits, masses, and radii), associated data (such as published radial velocity curves, photometric light curves, images, and spectra), and stellar parameters (such as magnitudes, positions, and temperatures). All the archived data are linked to the original literature reference.The archive provides tools to work with these data, including interactive tables (with plotting capabilities), interactive light curve viewer, periodogram service, transit and ephemeris calculator, and application program interface.The NASA Exoplanet Archive is the U.S. portal to the public CoRoT mission data for both the Exoplanet and Asteroseismology data sets. The NASA Exoplanet Archive also serves data related to Kepler Objects of Interest (Planet Candidates and the Kepler False Positives, KOI) in an integrated and interactive table containing stellar and transit parameters. In support of the Kepler Extended Mission, the NASA Exoplanet Archive will host transit modeling parameters, centroid results, several statistical values, and summary and detailed reports for all transit-like events identified by the Kepler Pipeline.

NASA science communications strategy  

NASA Astrophysics Data System (ADS)

In 1994, the Clinton Administration issued a report, 'Science in the National Interest', which identified new national science goals. Two of the five goals are related to science communications: produce the finest scientists and engineers for the 21st century, and raise scientific and technological literacy of all Americans. In addition to the guidance and goals set forth by the Administration, NASA has been mandated by Congress under the 1958 Space Act to 'provide for the widest practicable and appropriate dissemination concerning its activities and the results thereof'. In addition to addressing eight Goals and Plans which resulted from a January 1994 meeting between NASA and members of the broader scientific, education, and communications community on the Public Communication of NASA's Science, the Science Communications Working Group (SCWG) took a comprehensive look at the way the Agency communicates its science to ensure that any changes the Agency made were long-term improvements. The SCWG developed a Science Communications Strategy for NASA and a plan to implement the Strategy. This report outlines a strategy from which effective science communications programs can be developed and implemented across the agency. Guiding principles and strategic themes for the strategy are provided, with numerous recommendations for improvement discussed within the respective themes of leadership, coordination, integration, participation, leveraging, and evaluation.

Bayesian logistic regression analysis  

NASA Astrophysics Data System (ADS)

In this paper we present a Bayesian logistic regression analysis. It is found that if one wishes to derive the posterior distribution of the probability of some event, then, together with the traditional Bayes Theorem and the integrating out of nuissance parameters, the Jacobian transformation is an essential added ingredient. The application of the product rule gives the posterior of the unknown logistic regression coefficients. The Jacobian transformation then maps the posterior of these regression coefficients to the posterior of the corresponding probability of some event and some nuisance parameters. Finally, by way of the sumrule the nuissance parameters are integrated out.

An infrared solution to a national priority NASA ice detection and measurement problem  

NASA Astrophysics Data System (ADS)

NASA has a serious problem with ice that forms on the cryogenic-filled Space Shuttle External Tank (ET) that could endanger the crew and vehicle. This problem has defied resolution in the past. To find a solution, a cooperative agreement was developed between NASA-Kennedy Space Center (KSC) and the U.S. Army Tank-automotive and Armaments Research, Development & Engineering Center (TARDEC). This paper describes the need, initial investigation, solution methodology, and some results for a mobile near-infrared (IR) ice detection and measurement system developed by MDA of Canada and jointly tested by the U.S. Army TARDEC and NASA. Performance results achieved demonstrate that the pre-launch inspection system has the potential to become a critical tool in addressing NASA's ice problem.

Orbital Debris and NASA's Measurement Program  

NASA Astrophysics Data System (ADS)

Since the launch of Sputnik in 1957, the number of manmade objects in orbit around the Earth has dramatically increased. The United States Space Surveillance Network (SSN) tracks and maintains orbits on over nine thousand objects down to a limiting diameter of about ten centimeters. Unfortunately, active spacecraft are only a small percentage ( ~ 7%) of this population. The rest of the population is orbital debris or ``space junk" consisting of expended rocket bodies, dead payloads, bits and pieces from satellite launches, and fragments from satellite breakups. The number of these smaller orbital debris objects increases rapidly with decreasing size. It is estimated that there are at least 130,000 orbital debris objects between one and ten centimeters in diameter. Most objects smaller than 10 centimeters go untracked! As the orbital debris population grows, the risk to other orbiting objects, most importantly manned space vehicles, of a collision with a piece of debris also grows. The kinetic energy of a solid 1 cm aluminum sphere traveling at an orbital velocity of 10 km/sec is equivalent to a 400 lb. safe traveling at 60 mph. Fortunately, the volume of space in which the orbiting population resides is large, collisions are infrequent, but they do occur. The Space Shuttle often returns to earth with its windshield pocked with small pits or craters caused by collisions with very small, sub-millimeter-size pieces of debris (paint flakes, particles from solid rocket exhaust, etc.), and micrometeoroids. To get a more complete picture of the orbital-debris environment, NASA has been using both radar and optical techniques to monitor the orbital debris environment. This paper gives an overview of the orbital debris environment and NASA's measurement program.

NASA Science Budget Choices Criticized  

NASA Astrophysics Data System (ADS)

NASA's decision to focus its science efforts on large missions at the expense of smaller missions and research is misguided and will have a long-term negative impact on attracting and retaining scientists and engineers to NASA-related science, several scientists testified at a 2 March hearing. Witnesses at the hearing before the U.S. House of Representatives Science Committee included NASA Associate Administrator for the Science Mission Directorate Mary Cleave and members or chairs of four U.S. National Academy of Sciences (NAS) decadal surveys of various aspects of NASA science. The witnesses discussed cuts and delays to NASA projects proposed in the agency's Fiscal Year 2007 budget request. NASA's science budget would grow by 1.5 percent in FY2007, and then by just one percent per year in 2008-2011 (see Eos 87(9), 2006).

NASA's Interstellar Probe Mission  

NASA Astrophysics Data System (ADS)

Sending a spacecraft beyond the heliopause to begin the exploration of our local galactic neighborhood will be one of the grand scientific enterprises of the next century. NASA's Interstellar Probe will be the first spacecraft designed to explore the nearby interstellar medium and its interaction with our solar system. In the mission concept developed in 1999 by NASA's Interstellar Probe Science and Technology Definition Team, a 400-m diameter solar sail accelerates the spacecraft to ~15 AU/year. The principal objectives of the Interstellar Probe mission would be to (1) explore the nature of the ISM and its implications for the origin and evolution of matter in our galaxy and the universe; (2) explore the influence of the ISM on the solar system and its dynamics and evolution; (3) explore the impact of the solar system on the ISM as an example of a stellar system with its environment; and (4) explore the outer solar system in search of clues to its origin and to the nature of other planetary systems. To achieve these broad, interdisciplinary objectives, Interstellar Probe will include a suite of advanced, low-power instruments designed to measure the detailed properties of the plasma, neutral atoms, energetic particles, magnetic fields, and dust in the outer heliosphere and nearby ISM. This talk will summarizes the conceptual mission design and the technological challenges presented by this ambitious mission.

NASA scientific integrity policy  

NASA Astrophysics Data System (ADS)

On 16 December, NASA became the latest U.S. federal agency to issue a scientific integrity policy. It was issued less than 10 days after the U.S. National Oceanic and Atmospheric Administration (NOAA) issued its policy on the same topic (see "NOAA issues scientific integrity policy," Eos Trans. AGU, 92(50), 467, doi:10.1029/2011EO500004, 2011). The agency policies respond to earlier White House memos on the topic issued in 2009 and 2010. NASA is the fifth federal department or agency that has finalized a scientific integrity policy; the Department of the Interior and the National Science Foundation also have finalized their policies. As Eos went to press, 13 other policies were in near-final draft form, including those from the departments of Agriculture and Energy; the Environmental Protection Agency and the Department of Labor had indicated that they expected to submit their policies to the White House Office of Science and Technology Policy (OSTP) soon, OSTP director John Holdren wrote in a 21 December note on the office's Web site.

NASA's Origins Program  

NSDL National Science Digital Library

Since time immemorial, humans have asked such fundamental questions as "Are we alone" and "Where did we come from?". Taking on some of those fundamental questions through the use of scientific inquiry is the Origins program, operated under the auspices of NASA. As an introductory essay on the program authored by Alan Dresser on the site suggests: "The eruptive growth of 20th century astronomy has brought us an appreciation of how vast, old, and unearthly the universe is, and has left humanity struggling with a sense of our own significance consistent with the reality of who and what we are." With that rather awe-inspiring thought in mind, visitors will want to comb through the many insightful sections of the site, including those that provide answers (or at least what we know so far) to such questions as "Is there life on planets outside the solar system?" Additionally, visitors can read about NASA's different missions and learn about the new technologies under development that will allow voyages of discovery into space to continue these explorations over the coming decades.

NASA telerobotics technology highlights  

SciTech Connect

The goal of the National Aeronautics and Space Administration`s (NASA`s) Telerobotics Program, part of the over-all research program of the Office of Advanced Concepts and Technology (OACT), is to develop the technology in space-borne systems that enables new space tasks in Earth-orbiting satellite and platform servicing; robotic tending of science payloads and instruments; and planetary surface exploration, scientific sampling, and in situ analysis. Our objective is that by 2004, 50% of the extra-vehicular activity (EVA)-required operations on orbit and on planetary surfaces may be conducted via remote operation. The technologies developed for space have important dual uses for commercial areas such as medical robotics, agriculture, and subsea welding; this synergy is being actively encouraged. Moreover, mutually reciprocal collaboration with international partners (e.g., Japan and Russia) has received increasing attention. The purpose of this paper is to provide an overview of some of the ongoing program activities, which are described briefly.

X-SAR: The X-band synthetic aperture radar on board the Space Shuttle  

NASA Astrophysics Data System (ADS)

The X-band synthetic aperture radar (X-SAR) is the German/Italian contribution to the NASA/JPL Shuttle Radar Lab missions as part of the preparation for the Earth Observation System (EOS) program. The Shuttle Radar Lab is a combination of several radars: an L-band (1.2 GHz) and a C-band (5.3 GHz) multipolarization SAR known as SIR-C (Shuttle Imaging Radar); and an X-band (9.6 GHz) vertically polarized SAR which will be operated synchronously over the same target areas to deliver calibrated multifrequency and multipolarization SAR data at multiple incidence angles from space. A joint German/Italian project office at DARA (German Space Agency) is responsible for the management of the X-SAR project. The space hardware has been developed and manufactured under industrial contract by Dornier and Alenia Spazio. Besides supporting all the technical and scientific tasks, DLR, in cooperation with ASI (Agencia Spaziale Italiano) is responsible for mission operation, calibration, and high precision SAR processing. In addition, DLR developed an airborne X-band SAR to support the experimenters with campaigns to prepare for the missions. The main advantage of adding a shorter wavelength (3 cm) radar to the SIR-C radars is the X-band radar's weaker penetration into vegetation and soil and its high sensitivity to surface roughness and associated phenomena. The performance of each of the three radars is comparable with respect to radiometric and geometric resolution.

Implementing the space shuttle data processing system with the space generic open avionics architecture  

NASA Astrophysics Data System (ADS)

This paper presents an overview of the application of the Space Generic Open Avionics Architecture (SGOAA) to the Space Shuttle Data Processing System (DPS) architecture design. This application has been performed to validate the SGOAA, and its potential use in flight critical systems. The paper summarizes key elements of the Space Shuttle avionics architecture, data processing system requirements and software architecture as currently implemented. It then summarizes the SGOAA architecture and describes a tailoring of the SGOAA to the Space Shuttle. The SGOAA consists of a generic system architecture for the entities in spacecraft avionics, a generic processing external and internal hardware architecture, a six class model of interfaces and functional subsystem architectures for data services and operations control capabilities. It has been proposed as an avionics architecture standard with the National Aeronautics and Space Administration (NASA), through its Strategic Avionics Technology Working Group, and is being considered by the Society of Aeronautic Engineers (SAE) as an SAE Avionics Standard. This architecture was developed for the Flight Data Systems Division of JSC by the Lockheed Engineering and Sciences Company, Houston, Texas.

NASA's Advanced solid rocket motor  

NASA Astrophysics Data System (ADS)

The Advanced Solid Rocket Motor (ASRM) will not only bring increased safety, reliability and performance for the Space Shuttle Booster, it will enhance overall Shuttle safety by effectively eliminating 174 failure points in the Space Shuttle Main Engine throttling system and by reducing the exposure time to aborts due to main engine loss or shutdown. In some missions, the vulnerability time to Return-to-Launch Site aborts is halved. The ASRM uses case joints which will close or remain static under the effects of motor ignition and pressurization. The case itself is constructed of the weldable steel alloy HP 9-4-0.30, having very high strength and with superior fracture toughness and stress corrosion resistance. The internal insulation is strip-wound and is free of asbestos. The nozzle employs light weight ablative parts and is some 5,000 pounds lighter than the Shuttle motor used to date. The payload performance of the ASRM-powered Shuttle is 12,000 pounds higher than that provided by the present motor. This is of particular benefit for payloads delivered to higher inclinations and/or altitudes. The ASRM facility uses state-of-the-art manufacturing techniques, including continuous propellant mixing and direct casting.

A study of space shuttle plumes in the lower thermosphere  

NASA Astrophysics Data System (ADS)

During the space shuttle main engine burn, some 350 t of water vapor are deposited at between 100 and 115 km. Subsequent photodissociation of water produces large plumes of atomic hydrogen that can expand rapidly and extend for thousands of kilometers. From 2002 to 2007, the Global Ultraviolet Imager (GUVI) on NASA's Thermosphere Ionosphere, Mesosphere, Energetics and Dynamics (TIMED) satellite imaged many of these hydrogen plumes at Lyman ? (121.567 nm) while viewing in the nadir. The images reveal rapid plume expansion and occasional very fast transport to both north and south polar regions. Some plumes persist for up to 6 d. Near-simultaneous direct detections of water vapor were made with the Sounding of the Atmosphere with Broadband Emission Radiometry (SABER) instrument, also on TIMED. We compare the spreading of the hydrogen plume with a two-dimensional model that includes photodissociation as well as both vertical and horizontal diffusion. Molecular diffusion appears to be sufficient to account for the horizontal expansion, although wind shears and turbulent mixing may also contribute. We compare the bulk motion of the observed plumes with wind climatologies derived from satellite observations. The plumes can move much faster than predictions of wind climatologies. But dynamical processes not contained in wind climatologies, such as the quasi-two-day wave, can account for at least some of the high speed observations. The plume phenomena raise a number of important questions about lower thermospheric and mesospheric processes, ranging from dynamics and chemistry to polar mesospheric cloud formation and climatology.

Social and cultural issues during Shuttle/Mir space missions.  

PubMed

A number of interpersonal issues relevant to manned space missions have been identified from the literature. These include crew tension, cohesion, leadership, language and cultural factors, and displacement. Ground-based studies by others and us have clarified some of the parameters of these issues and have indicated ways in which they could be studied during actual space missions. In this paper, we summarize some of our findings related to social and cultural issues from a NASA-funded study conducted during several Shuttle/Mir space missions. We used standardized mood and group climate measures that were completed on a weekly basis by American and Russian crew and mission control subjects who participated in these missions. Our results indicated that American subjects reported more dissatisfaction with their interpersonal environment than their Russian counterparts, especially American astronauts. Mission control personnel were more dysphoric than crewmembers, but both groups were significantly less dysphoric than other work groups on Earth. Countermeasures based on our findings are discussed which can be applied to future multicultural space missions. PMID:11708371

Relative efficacy of the proposed Space Shuttle antimotion sickness medications  

NASA Astrophysics Data System (ADS)

Space motion sickness has been estimated as affecting between 1/3 and 1/2 of all space flight participants. NASA has at the moment proposed a combination of promethazine and ephedrine ( P/E) and one of scopolamine and dextroamphetamine ( S/D), both given orally, as well as a transdermally applied scopolamine (TAS), as preventive and ameliorative measures. The reported double-blind study tests the early phase actions and efficacy of the transdermal scopolamine (Transderm ™-V of ALZA Corporation) and compares these in detail to the oral medications. Motion sickness resistance was tested by standardized head movements while accelerating at 0.2°/sec 2 to a maximum rotation of 240°/sec, with an intermediate plateau of 10 min at 180°/sec. To permit weighting motion sickness protection against other system influences, cardiovascular, psychological (subjective and objective), and visual parameter changes were documented for the three therapeutic modes. The relative impact of the various modalities on operational and experimental components of space missions is discussed. A comparison to intramuscularly administered promethazine (a backup therapeutic mode suggested for Space Shuttle use) is also included.

NASA balloon science program  

NASA Astrophysics Data System (ADS)

Scientific ballooning has for decades enabled science and technology investigations in near space with significant results from relatively modest investments in the instruments. In some cases the investigations enabled orbital missions, whereas others were competitive with space mis-sions. A sea change in scientific ballooning occurred in the 1990's with the inauguration of Long Duration Balloon (LDB) flights averaging about 15 days in one circumnavigation of Antarctica using conventional zero-pressure balloons floating in nearly constant sunlight. Their 0.8 -1.1 million cubic meter balloons carried 1 -2 ton science instruments as part of suspended payloads approaching 3 tons. The nearly routine achievement during the past decade of two circumnavi-gations averaging about 30 days and triple circumnavigations lasting up to 42 days has greatly increased expectations of scientific users. These circumpolar flights have been spectacularly successful, with many investigations utilizing multiple flights of payloads that were recovered and refurbished to minimize the life-cycle costs. NASA has been developing a super-pressure balloon for LDB flights at non-polar latitudes that would bring another sea change in scientific ballooning, while supporting a broader range of scientific investigations. A 7 million cubic feet test balloon flown 54 days during the 2008-2009 austral season with less than about 100 m altitude variations demonstrates the promise of this new balloon carrier. It shows that we are a step closer to Ultra Long Duration Balloon (ULDB) flights of about 100 days. The 2010 Na-tional Research Council report "Revitalization of NASA's Suborbital Program" recommends that NASA should provide increased funds for complex payloads that use its present LDB capability, and especially for ULDB payloads when that capability becomes available. Long-duration flights in both polar and non-polar regions will undoubtedly confirm the important contributions that ballooning can make in disciplines such as Cosmic Microwave Background and Infrared Science, High Energy Astrophysics, Particle Astrophysics, Solar Physics, Geospace Science, and Earth Science. Some results from past balloon-borne measurements and/or ex-pected results from ongoing and planned balloon-borne experiments in these disciplines will be presented.

SIR-B (Shuttle Imaging Radar) images  

NASA Astrophysics Data System (ADS)

Space Shuttle Mission 41G was launched from Kennedy Space Center on 5 October 1984. Aboard the instrument pallet was the 1.28 GHz (L-band) Shuttle Imaging Radar (SIR-B) intended to obtain SAR images for geology, agriculture, forestry, hydrology, and ocean sciences. Data were intended to be transmitted to earth via a Ku band communication link with the Tracking and Data Relay Satellite (TDRS). Unfortunately, the shuttle's trainable Ku communication antenna failed to lock onto the TDRS, making high rate data transmission impossible. A real-time-revised observation program, of much smaller scale than the original plan, was substituted making use of an onboard tape recorder. The flight crew recorded radar data on the recorder and then reoriented the shuttle itself, with the Ku antenna fixed, to point to TDRS and transmit the data. The revised plan eliminated about 80 percent of the planned data swaths and shortened the remainder. A number of errors crept into the SIR-B experiments as a result of the sudden and complete reprogramming as well as a problem in latching the radar antenna. Finally, an electrical problem in the radar caused an 8-10 dB reduction in signal-to-noise ratio.

Highlighting Your Science to NASA  

NASA Astrophysics Data System (ADS)

An effort is underway to provide greater visibility within NASA headquarters, and to those who provide funding to NASA, of the outstanding work that is being performed by scientists involved in the Solar System Exploration Research and Analysis Programs, most of whom are DPS members. In support of this effort, a new feature has been developed for the NASA Headquarters Solar System Exploration Division web site whereby researchers can provide a synopsis of their current research results. The site (http://solarsystem.nasa.gov/spotlight/ - Username: your email address Password: sse) is an online submission area where NASA-funded scientists can upload the results of their research. There they provide their contact information, briefly describe their research, and upload any associated images or graphics. The information is available to a limited number of reviewers and writers at JPL. Each month, one researcher's work will be chosen as a science spotlight. After a writer interviews the scientist, a brief Power Point presentation that encapsulates their work will be given to Dr. Colleen Hartman at NASA headquarters. She will then present the exciting findings to Associate Administrator for Space Science, Dr. Ed Weiler. The information from some of these highlights can serve as a basis to bring Principal Investigators to NASA Headquarters for exposure to media through Space Science Updates on NASA television. In addition, the science results may also be incorporated into briefing material for the Office of Management and Budget and congressional staffers. Some spotlights will also be converted into feature stories for the Solar System Exploration website so the public, too, can learn about exciting new research. The site, http://solarsystem.nasa.gov/, is one of NASA's most visited. Over the past decade, there has been a trend of flat budgets for Research and Analysis activities. By giving more visibility to results of Solar System research, our goal is to encourage higher program funding levels from Congress and demonstrate the relevance of NASA research to the American public in general.

Lidar in-space technology experiment (LITE); NASA's first in-space lidar system for atmospheric research  

SciTech Connect

The Lidar In-Space Technology Experiment (LITE) is being developed by NASA/Langley Research Center for flight on the Space Shuttle. The system will detect stratospheric and tropospheric aerosols, probe the planetary boundary layer, measure cloud top heights, and measure atmospheric temperature and density in the range of 10 to 40 km. The system consists of a nominal 1 m diameter telescope receiver, a three-color neodymium:YAG laser transmitter, and the system electronics. The instrument makes extensive use of Space Shuttle resources for electrical power, thermal control, and command and data handling. The instrument will fly on the Space Shuttle in mid-1993. This paper presents the engineering aspects of the design, fabrication, integration, and operation of the instrument. A companion paper by members of the LITE Science Steering Group that details the science aspects of LITE is the preparation and will be published at a later time.

TRW Ships NASA's Chandra X-ray Observatory To Kennedy Space Center  

NASA Astrophysics Data System (ADS)

Two U.S. Air Force C-5 Galaxy transport planes carrying the observatory and its ground support equipment landed at Kennedy's Space Shuttle Landing Facility at 2:40 p.m. EST this afternoon. REDONDO BEACH, CA.--(Business Wire)--Feb. 4, 1999--TRW has shipped NASA's Chandra X-ray Observatory ("Chandra") to the Kennedy Space Center (KSC), in Florida, in preparation for a Space Shuttle launch later this year. The 45-foot-tall, 5-ton science satellite will provide astronomers with new information on supernova remnants, the surroundings of black holes, and other celestial phenomena that produce vast quantities of X-rays. Cradled safely in the cargo hold of a tractor-trailer rig called the Space Cargo Transportation System (SCTS), NASA's newest space telescope was ferried on Feb. 4 from Los Angeles International Airport to KSC aboard an Air Force C-5 Galaxy transporter. The SCTS, an Air Force container, closely resembles the size and shape of the Shuttle cargo bay. Over the next few months, Chandra will undergo final tests at KSC and be mated to a Boeing-provided Inertial Upper Stage for launch aboard Space Shuttle Columbia. A launch date for the Space Shuttle STS-93 mission is expected to be announced later this week. The third in NASA's family of Great Observatories that includes the Hubble Space Telescope and the TRW-built Compton Gamma Ray observatory, Chandra will use the world's most powerful X-ray telescope to allow scientists to "see" and monitor cosmic events that are invisible to conventional optical telescopes. Chandra's X-ray images will yield new insight into celestial phenomena such as the temperature and extent of gas clouds that comprise clusters of galaxies and the superheating of gas and dust particles as they swirl into black holes. A TRW-led team that includes the Eastman Kodak Co., Raytheon Optical Systems Inc., and Ball Aerospace & Technologies Corp. designed and built the Chandra X-ray Observatory for NASA's Marshall Space Flight Center. The Smithsonian Astrophysical Observatory will manage the Chandra science mission for NASA from the Chandra X-ray Observatory Center in Cambridge, Mass. TRW has been developing scientific, communications and environmental satellite systems for NASA since 1958. In addition to building the Chandra X-ray Observatory, the company is currently developing the architectures and technologies needed to implement several of NASA's future space science missions, including the Next Generation Space Telescope, the Space Inteferometry Mission, both part of NASA's Origins program, and Constellation-X, the next major NASA X-ray mission after Chandra.

Nonlinear rotational maneuver and vibration damping of NASA SCOLE system  

NASA Astrophysics Data System (ADS)

We treat the question of large rotational maneuver and vibration stabilization of NASA Spacecraft Control Laboratory Experiment (SCOLE) system. The mathematical model of SCOLE system includes the dynamical equations for rigid body slew maneuver and three-dimensional vibration of the flexible beam and the reflector with an offset mass. The design approach taken here is to decompose the rigid mode control from vibration stabilization. Feedback input (Shuttle torque)-output (attitude angles) map linearization technique is used for designing attitude control system for large-angle slewing. Linearization of the input-output (i-o) map is accomplished by nonlinear inversion theory. It is shown that attitude control system asymptotically decouples the flexible dynamics and a linear feedback law is easily designed for vibration suppression. For the synthesis of the control law an observer is designed. Simulation results are presented to show that in the closed-loop system large angle maneuvers can be accomplished using only the measured state variables.

Advanced QCM controller for NASA's plume impingement contamination-II  

NASA Astrophysics Data System (ADS)

Currently, no accurate models or recent data exist for modeling contamination from spacecraft thrusters to meet the stringent requirements of the International Space Station (ISS). Few flight measurements of contaminant deposition from spacecraft thrusters have been made, and no measurements have been made for angles away from the plume centerline. The Plume Impingement Contamination-II (PIC-II) experiment is planned to provide such measurements using quartz crystal microbalances placed into the plume of a Shuttle Orbiter RCS thruster. To this end, the Johns Hopkins University Applied Physics Laboratory (APL) has supported NASA in the development of the PIC-II experiment Flight Electronics Unit known as the Remote Arm TQCM System (RATS), which will measure the contamination in the Shuttle Obiter RCS thruster. The development was based on an ongoing effort between the APL and QCM Research to develop an inexpensive, miniature TQCM controller based on a legacy of QCM controllers developed at the APL. PIC-II will provide substantial improvements over previous systems, including higher resolution, greater flexibility, intensive housekeeping, and in-situ operational control. Details of the experiment hardware and measurement technique are given. The importance of the experiment to the ISS and the general plume contamination community is discussed.

Lunar Surface Architecture Utilization and Logistics Support Assessment  

NASA Astrophysics Data System (ADS)

Crew and equipment utilization and logistics support needs for the point of departure lunar outpost as presented by the NASA Lunar Architecture Team (LAT) and alternative surface architectures were assessed for the first ten years of operation. The lunar surface architectures were evaluated and manifests created for each mission. Distances between Lunar Surface Access Module (LSAM) landing sites and emplacement locations were estimated. Physical characteristics were assigned to each surface element and operational characteristics were assigned to each surface mobility element. Stochastic analysis was conducted to assess probable times to deploy surface elements, conduct exploration excursions, and perform defined crew activities. Crew time is divided into Outpost-related, exploration and science, overhead, and personal activities. Outpost-related time includes element deployment, EVA maintenance, IVA maintenance, and logistics resupply. Exploration and science activities include mapping, geological surveys, science experiment deployment, sample analysis and categorizing, and physiological and biological tests in the lunar environment. Personal activities include sleeping, eating, hygiene, exercising, and time off. Overhead activities include precursor or close-out tasks that must be accomplished but don't fit into the other three categories such as: suit donning and doffing, airlock cycle time, suit cleaning, suit maintenance, post-landing safing actions, and pre-departure preparations. Equipment usage time, spares, maintenance actions, and Outpost consumables are also estimated to provide input into logistics support planning. Results are normalized relative to the NASA LAT point of departure lunar surface architecture.

Risk Analysis of the Space Shuttle: Pre-Challenger Bayeisan Prediction of Failure  

SciTech Connect

Dalal et al performed a statistical analysis of field and nozzle O-ring data collected prior to the ill-fated launch of the Challenger in January 1986. The purpose of their analysis was to show how statistical analysis could be used to provide information to decisionmakers prior to the launch, information that could have been expected to lead to a decision to abort the launch due to the low temperatures (~30o F.) present at the launch pad on the morning of the scheduled launch. Dalal et al. performed a frequentist analysis of the O-ring data, and found that a logistic regression model provided a relatively good fit to the past data. In the second portion of their paper, Dalal et al. propagated parameter uncertainties through the fitted logistic regression model in order to estimate the probability of shuttle failure due to O-ring failure at the estimated launch temperature of ~30o F. Because their analysis was frequentist in nature, probability distributions representing epistemic uncertainty in the input parameters were not available, and the authors had to resort to an approximate approach based on bootstrap confidence intervals. In this paper, we will re-evaluate the analyses of Dalal et al. from a Bayesian perspective. Markov chain Monte Carlo (MCMC) sampling will be used to sample from the joint posterior distribution of the model parameters, and to sample from the posterior predictive distributions at the estimated launch temperature, a temperature that had not been observed in prior launches of the space shuttle. Uncertainties, which are represented by probability distributions in the Bayesian approach, are propagated through the model to obtain a probability distribution for O-ring failure, and subsequently for shuttle failure as a result of O-ring failure. No approximations are required in the Bayesian approach and the resulting distributions can be input to a decision analysis to obtain expected utility for the decision to launch.

Probabilistic risk assessment of the Space Shuttle. Phase 3: A study of the potential of losing the vehicle during nominal operation, volume 1  

NASA Astrophysics Data System (ADS)

This document is the Executive Summary of a technical report on a probabilistic risk assessment (PRA) of the Space Shuttle vehicle performed under the sponsorship of the Office of Space Flight of the US National Aeronautics and Space Administration. It briefly summarizes the methodology and results of the Shuttle PRA. The primary objective of this project was to support management and engineering decision-making with respect to the Shuttle program by producing (1) a quantitative probabilistic risk model of the Space Shuttle during flight, (2) a quantitative assessment of in-flight safety risk, (3) an identification and prioritization of the design and operations that principally contribute to in-flight safety risk, and (4) a mechanism for risk-based evaluation proposed modifications to the Shuttle System. Secondary objectives were to provide a vehicle for introducing and transferring PRA technology to the NASA community, and to demonstrate the value of PRA by applying it beneficially to a real program of great international importance.

NASA Announces Contest to Name X-Ray Observatory  

NASA Astrophysics Data System (ADS)

NASA is searching for a new name for the Advanced X-ray Astrophysics Facility (AXAF), currently scheduled for launch Dec. 3, 1998, from the Space Shuttle Columbia. AXAF is the third of NASA's Great Observatories, after the Hubble Space Telescope and the Compton Gamma Ray Observatory. Once in orbit around Earth, it will explore hot, turbulent regions in the universe where X-rays are produced. Dr. Alan Bunner, director of NASA's Structure and Evolution of the universe science program, will announce April 18 at the National Science Teacher's Association meeting in Las Vegas, NV, the start of a contest, open to people worldwide, to find a new name for the observatory. Entries should contain the name of a person (not living), place, or thing from history, mythology, or fiction. Contestants should describe in a few sentences why this choice would be a good name for AXAF. The name must not have been used before on space missions by NASA or other organizations or countries. The grand prize will be a trip to NASA's Kennedy Space Center in Cape Canaveral, FL, to see the launch of the satellite aboard the Space Shuttle. Ten runner-up prizes will be awarded and all entrants will receive an AXAF poster. The grand prize is sponsored by TRW Inc., AXAF's prime contractor. The AXAF Science Center in Cambridge, MA, will run the contest for NASA. NASA will announce the final selection of the winning name later this year. Entries also can be mailed to: AXAF Contest, AXAF Science Center, Office of Education and Public Outreach, 60 Garden Street, MS 83, Cambridge, MA 02138. Mailed entries must be postmarked no later than June 30, 1998. All entries must state a name for the mission, along with the reason the name would make a good choice. The observatory, now in the final stages of assembly and testing at TRW's facility in Redondo Beach, CA, is more than 45 feet long and weighs 10,500 pounds. AXAF is the largest and most powerful X-ray observatory ever constructed, and its images will be more than ten times sharper than any previous X-ray telescope. This focusing power of the telescope is equivalent to the ability to read a newspaper at a distance of half a mile. Cosmic X-rays are produced by violent events, such as when stars explode or galaxies collide. X-rays also are emitted by matter heated to many millions of degrees as it swirls toward a black hole. The only way to observe these and other extremely hot astronomical sources is with a space-based X-ray telescope. Editor's Note (Dec 21, 1998): How the Chandra X-ray Observatory got its name: See the details of the contest and winning essays and the press release.

Human interactions during Shuttle/Mir space missions.  

PubMed

To improve the interpersonal climate of crewmembers involved with long-duration space missions, it is important to understand the factors affecting their interactions with each other and with members of mission control. This paper will present findings from a recently completed NASA-funded study during the Shuttle/Mir program which evaluated in-group/out-group displacement of negative emotions; changes in tension, cohesion, and leader support over time; and cultural differences. In-flight data were collected from 5 astronauts, 8 cosmonauts, and 42 American and 16 Russian mission control personnel who signed informed consent. Subjects completed a weekly questionnaire that assessed their mood and perception of their work group's interpersonal climate using questions from well-known, standardized measures (Profile of Mood States, Group and Work Environment Scales) and a critical incident log. There was strong evidence for the displacement of tension and dysphoric emotions from crewmembers to mission control personnel and from mission control personnel to management. There was a perceived decrease in commander support during the 2nd half of the missions, and for American crewmembers a novelty effect was found on several subscales during the first few months on-orbit. There were a number of differences between American and Russian responses which suggested that the former were less happy with their interpersonal environment than the latter. Mission control personnel reported more tension and dysphoria than crewmembers, although both groups scored better than other work groups on Earth. Nearly all reported critical incidents came from ground subjects, with Americans and Russians showing important differences in response frequencies. PMID:11858274

Logistics of underground coal mining  

SciTech Connect

This book investigates and analyzes the major logistical functions associated with underground coal mining in the U.S.--the activities and services that indirectly support the producing sections of a mining operation. These logistics activities include transportation of personnel, supplies, and equipment; transporation of coal and rock; electrical distribution and communications systems; water handling; hydraulics; and ventilation systems. The book provides an understanding of how these functions impact coal production in terms of time, cost, and safety. The support services for underground coal mine production are so essential that no coal would be produced without them. Since no two mines are alike, logistics problems can be quite varied. Developing and improving systems which, not only directly but indirectly, affect production is an extremely important factor in mining economics. This book presents extensive analytical data which demonstrate the significance of logistical controls on the profitability of coal production. Numerous aspects of underground mine logistics and the costs of various logistical functions are investigated; cost analyses of the major logistics categories clearly identify a particular category's effects on various equipment combinations and seam heights. Current mining practices and problems are reviewed, accompanied by opinions and comments from mining industry representatives; and short- and long-term areas for further research are suggested. The book contains an extensive set of tables for illustrative purposes.

Current rectification by spontaneous symmetry breaking in coupled nanomechanical shuttles.  

PubMed

We investigate the transport and the dynamical properties of tunnel-coupled double charge shuttles. The oscillation frequencies of two shuttles are mode locked to integer multiples of the applied voltage frequency omega. We show that left-right-symmetric double shuttles may generate direct net current due to bistable motions caused by parametric instability. The symmetry-broken direct current appears near omega = Omega0/(2j-1), (j = 1,2,...), where Omega0 is the dressed resonance frequency of the relative motion of the two shuttles. PMID:17155766

NASA Carbon Monitoring System Program  

NASA Astrophysics Data System (ADS)

NASA has recently begun a focused program to provide products on the amount and distribution of carbon reservoirs and fluxes in the global environment informed by the increasing global observational capability for these quantities developed by NASA and its interagency and international partners. This program, known as a Carbon Monitoring System (CMS), serves as a user-responsive, product-oriented overlay onto the existing observational, modeling, and research programs sponsored by NASA's Earth Science Division (ESD). Initial emphasis is on two pilot products - one on terrestrial biomass and one on integrated emission/uptake ("flux"), as well as a "scoping study" that will enable longer-term planning built around the increasing global observational capability NASA expects to be launching in the next few years (e.g., Landsat Data Continuity Mission in 2012, reflight of Orbiting Carbon Observatory in 2013, decadal survey missions including ICESat-II in 2015 and DESDynI in 2017). Initial efforts on the pilot products are based largely at three NASA centers (Ames, Goddard, Jet Propulsion Laboratory), but will draw on the broader expertise of the research community through workshops (e.g., one held in Boulder in July, 2010) as well as a planned solicitation for a Science Definition Team to provide broader guidance into the development, evaluation, and future evolution of the pilot products. The NASA CMS activity, with its emphasis on utilization of NASA remote-sensing data, will complement related efforts of other Federal agencies; coordination with other agencies will be carried out through the US Global Change Research Program. In this talk, steps taken to initiate this activity in FY2010 and plans for its evolution into the future will be presented.

Cargo loading onto kinesin powered molecular shuttles.  

PubMed

Cells have evolved sophisticated molecular machinery, such as kinesin motor proteins and microtubule filaments, to support active intracellular transport of cargo. While kinesins tail domain binds to a variety of cargoes, kinesins head domains utilize the chemical energy stored in ATP molecules to step along the microtubule lattice. The long, stiff microtubules serve as tracks for long-distance intracellular transport. These motors and filaments can also be employed in microfabricated synthetic environments as components of molecular shuttles. In a frequently used design, kinesin motors are anchored to the track surface through their tails, and functionalized microtubules serve as cargo carrying elements, which are propelled by these motors. These shuttles can be loaded with cargo by utilizing the strong and selective binding between biotin and streptavidin. The key components (biotinylated tubulin, streptavidin, and biotinylated cargo) are commercially available. Building on the classic inverted motility assay, the construction of molecular shuttles is detailed here. Kinesin motor proteins are adsorbed to a surface precoated with casein; microtubules are polymerized from biotinylated tubulin, adhered to the kinesin and subsequently coated with rhodamine-labeled streptavidin. The ATP concentration is maintained at subsaturating concentration to achieve a microtubule gliding velocity optimal for loading cargo. Finally, biotinylated fluorescein-labeled nanospheres are added as cargo. Nanospheres attach to microtubules as a result of collisions between gliding microtubules and nanospheres adhering to the surface. The protocol can be readily modified to load a variety of cargoes such as biotinylated DNA, quantum dots or a wide variety of antigens via biotinylated antibodies. PMID:21085103

A simulation model for probabilistic analysis of Space Shuttle abort modes  

NASA Astrophysics Data System (ADS)

A simulation model which was developed to provide a probabilistic analysis tool to study the various space transportation system abort mode situations is presented. The simulation model is based on Monte Carlo simulation of an event-tree diagram which accounts for events during the space transportation system's ascent and its abort modes. The simulation model considers just the propulsion elements of the shuttle system (i.e., external tank, main engines, and solid boosters). The model was developed to provide a better understanding of the probability of occurrence and successful completion of abort modes during the vehicle's ascent. The results of the simulation runs discussed are for demonstration purposes only, they are not official NASA probability estimates.

Learning Resources on Ultraviolet Astronomy: The Shuttle-Borne Spacelab/Astro Missions  

NASA Astrophysics Data System (ADS)

Beyond the blue, beyond the violet, and into the ultraviolet part of the electromagnetic spectrum, the radiant universe appears strangely altered. At these shorter wavelengths and higher photon energies, the hottest stars shine brightly, while the cooler more common stars like the Sun virtually disappear from view. Clusters and associations of young stars are dominated by just a few massive ultraviolet-bright stars, while ancient globular clusters are reduced to their hottest, most rapidly evolving members. Spiral galaxies that look like graceful pinwheels in visible-light images are transformed into knotty webs --- each knot containing thousands of young hot stars. And the space between the stars, clusters, and galaxies appears profoundly black --- up to 100 times darker than the nighttime sky as seen at visible wavelengths. Until the last decade, our view of the ultraviolet universe was impeded by the stratospheric ozone layer that protects life on Earth from the Sun's harmful UV radiation. Subsequent balloon, sounding rocket, and satellite flights have yielded fascinating glimpses of the ultraviolet universe. In 1990, the Space Shuttle Columbia flew the Spacelab/Astro-1 mission. Astro is the first and only true astronomical observatory to operate onboard the Space Shuttle. It consists of 3 ultraviolet telescopes which are attached to a single pointing system in the Shuttle bay. During the Astro-1 mission, these instruments obtained UV images and spectra of hundreds of astronomical objects. Learning resources relating to this mission include a new slide set and booklet, ``Beyond the Blue: Greatest Hits of the Ultraviolet Imaging Telescope,'' which is being distributed by the ASP through its mail-order catalogue. There is also a teacher's guide with activities, ``Astro-1: Seeing in a New Light'' which is available from the NASA Teacher Resource Laboratories. Sources of information on the upcoming flight of Spacelab/Astro-2 aboard the Endeavour (currently scheduled for February--March 1995) will be discussed.

Analytical impact models and experimental test validation for the Columbia shuttle wing leading edge panels.  

SciTech Connect

This paper describes the analyses and the experimental mechanics program to support the National Aeronautics and Space Administration (NASA) investigation of the Shuttle Columbia accident. A synergism of the analysis and experimental effort is required to insure that the final analysis is valid - the experimental program provides both the material behavior and a basis for validation, while the analysis is required to insure the experimental effort provides behavior in the correct loading regime. Preliminary scoping calculations of foam impact onto the Shuttle Columbia's wing leading edge determined if enough energy was available to damage the leading edge panel. These analyses also determined the strain-rate regimes for various materials to provide the material test conditions. Experimental testing of the reinforced carbon-carbon wing panels then proceeded to provide the material behavior in a variety of configurations and strain-rates for flown or conditioned samples of the material. After determination of the important failure mechanisms of the material, validation experiments were designed to provide a basis of comparison for the analytical effort. Using this basis, the final analyses were used for test configuration, instrumentation location, and calibration definition in support of full-scale testing of the panels in June 2003. These tests subsequently confirmed the accident cause.

The Ascent Study - Understanding the Market Environment for the Follow-on to the Space Shuttle  

NASA Astrophysics Data System (ADS)

The ASCENT Study - Understanding the Market Environment for the Follow-on to NASA's Marshall Space Flight Center in Huntsville, Alabama, awarded a contract (base plus option amounting to twenty months of analysis) to Futron Corporation in June 2001 to investigate the market environment, and explore the price elasticity attributes, relevant for the introduction of the Second Generation Reusable Launch Vehicle (the follow-on to the Space Shuttle) in the second decade of this century. This work is known as the ASCENT Study (Analysis of Space Concepts Enabled by New Transportation) and data collection covering a total of 42 different sectors took place during 2001. Modeling and forecasting activities for 26 of these markets (all of them international in nature) have been taking place throughout 2002, and the final results of the ASCENT Study, which include 20 year forecasts, are due by the end of January, 2003. This paper describes the markets being analyzed for the ASCENT Study, and includes some preliminary findings in terms of launch vehicle demand during the next 20 years, broken down by mass class and mission type. Amongst these markets are the potential public space travel opportunities. When completed, the final report of the ASCENT Study is expected to represent a significant reference document for all business development, financing and planning activities in the space industry for some time to come. One immediate use will be as a key factor in determining the cargo capability and launch rates to be used for designing the follow-on to the Space Shuttle. The Study will also provide NASA with a quantified indication of the extent to which the lower cost to orbit, made possible by a new class of launch vehicle, will bring into being new markets.
