  • A program of data synthesis from the ALSEP/CPLEE ALSEP/SIDE, and Explorer 35 magnetometer to investigate lunar terminator and nightside particle fluxes and surface interactions 
    Reasoner, David Lukens, 1941- (Rice University, 1976-02-02)
    Lunar nightside electron fluxes were studied with the aid of the ALSEP/CPLEE (Charged Particle Lunar Environment Experiment) and other instruments. A study was also made of the shadowing of magnetotail plasma sheet electrons ...
  • A Proposed Hypothetical Exploration Mission in the Flamsteed Crater Region of the Moon 
    Vaughan, Otha H. (George C. Marshall Space Flight Center, 1967-09-14)
    A hypothetical 14-day lunar surface mission is proposed for two astronauts to investigate the lunar terrain and larger features about a preselected landing site. Because the Surveyor I spacecraft soft-landed in the Flamsteed ...
  • A trade-off study of various methods of releasing the LEAM dust covers 
    Cooper, J. W. (Bendix Aerospace Systems Division, 1971)
    At PDR, NASA has asked BxA to re-examine the present reefing line/pyrotechnic squib plans to be sure they are optimized with respect to reliability and other pertinent engineering parameters.

    This report presents a Failure Mode, Effects and Criticality Analysis (FMECA) performed on the Data Transmitter and documented in the attached worksheets.
  • A2 ALSEP Data Transmitter reliability prediction 
    Fox, T. W. (Bendix Aerospace Systems Division, 1970)
    This report presents the Data Transmitter reliability prediction estimates derived through the studies of Data Transmitter Failure Mode, Effects and Criticality Analysis (FMECA) and Data Transmitter Parts Application ...
  • A2 HFE DH15 anomaly investigation 
    Gilson, R. (Bendix Corporation, Aerospace Systems Division, 1971)
    Since 219/10/27/56 EGMT, data from A2 Heat Flow Experiment probe 2 thermocouple reference bridge Channel DH15 (DH91=1110) has exhibited symptoms that indicate a possible failure within the HFE electronics. At the above ...
  • Acceleration of thermal ions at the lunar surface : Apollo XII observations 
    Balsiger, H.; Freeman, John W.; Hills, H. Kent. (Department of Space Science, Rice University, 1970)
    An experiment designed to measure the differential energy spectrum and a coarse mass spectrum of ions near the lunar surface (Suprathermal Ion Detector Experiment) was deployed by the Apollo XII astronauts. This experiment ...
