    Construction and Resource Utilization Explorer: Regolith Characterization Using a Modular Instrument Suite and Analysis Tools (2005)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The Construction Resource Utilization Explorer (CRUX) is a technology maturation project for the U.S. National Aeronautics and Space Administration to provide enabling technology for lunar and planetary surface operations (LPSO). The CRUX will have 10 instruments, a data handling function (Mapper - with features of data subscription, fusion, interpretation, and publication through geographical information system [GIs] displays), and a decision support system DSS) to provide information needed to plan and conduct LPSO. Six CRUX instruments are associated with an instrumented drill to directly measure regolith properties (thermal, electrical, mechanical, and textural) and to determine the presence of water and other hydrogen sources to a depth of about 2 m (Prospector). CRUX surface and geophysical instruments (Surveyor) are designed to determine the presence of hydrogen, delineate near subsurface properties, stratigraphy, and buried objects over a broad area through the use of neutron and seismic probes, and ground penetrating radar. Techniques to receive data from existing space qualified stereo pair cameras to determine surface topography will also be part of the CRUX. The Mapper will ingest information from CRUX instruments and other lunar and planetary data sources, and provide data handling and display features for DSS output. CRUX operation will be semi-autonomous and near real-time to allow its use for either planning or operations purposes.

    Space Shuttle Orbiter Reaction Jet Driver (RJD): Independent Technical Assessment/Inspection (ITA/I) Report, Version 1.0 (2005)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: The Space Shuttle Program (SSP) has a zero-fault-tolerant design related to an inadvertent firing of the primary reaction control jets on the Orbiter during mated operations with the International Space Station (ISS). Failure modes identified by the program as a wire-to-wire "smart" short or a Darlington transistor short resulting in a failed-on primary thruster during mated operations with ISS can drive forces that exceed the structural capabilities of the docked Shuttle/ISS structure. The assessment team delivered 17 observations, 6 findings and 15 recommendations to the Space Shuttle Program.

    Fire, Explosion, Compatibility and Safety Hazards of Hydrogen Peroxide (2005)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: High-test hydrogen peroxide (HP) is an energetic liquid with widespread use in a variety of industrial and aerospace applications. In recent years, there has been increased interest in its use as a "green" or environmentally benign propellant in spacecraft and defense propulsion and power systems. HP, however, can be a significant hazard if not properly handled. In addition, hydrogen peroxide is unstable when exposed to trace contaminants, which may catalyze decomposition and result in violent thermal runaway. Many advanced and newly developed alloys, polymers, composites and other construction materials (such as those used in tankage and piping systems) have not been tested for compatibility with hydrogen peroxide. The reliability of extrapolating from short-term compatibility test results to long-term compatibility has not yet been fully assessed. Therefore, the users and designers of HP systems must be aware of these hazards and unknowns and take the appropriate precautions.

    The Role of Toxicity Testing in NASA's Future Missions (2005)
    In:  Other Sources
    Details
    Publication Date: 2019-07-18
    Description: NASA has deemed it necessary to perform the Toxicity Test (offgassing of toxic products) on all non-metallic materials proposed for use in habitable environments onboard the Shuttle and International Space Station flS,!J. This requirement stems from the desire to maintain a healthy, breathable atmosphere for the astronauts. As Shuttle missions have lengthened and with the habitation of the International Space Station, the need for understanding and controlling the contaminants in breathable atmospheres has increased. The increased duration of humans in space present two concerns to the astronauts with regard to their breathing air: 1. Breathing the on-board air. 2. Improved cleaning/filtering of existing air. Trends using existing toxicity data for materials and an understanding of the air cleaning/filtering capabilities in relation to Spacecraft Maximum Allowable Concentrations (SMAC) of offgassed components are explored. Recommendations are made for materials selection practices that should be followed to ensure a safe and healthy breathing environment for astronauts aboard these long term projects. The importance and relevance of Toxicity testing and materials selection in conjunction with the new NASA missions of creating a human presence on the Moon and traveling to Mars are described.
