  • ALSEP long term operational planning : (interim) 
    Perkins, Derek. (Bendix, Aerospace Systems Division, 1973)
    The purpose of this analysis is to determine the optimum long term operational profile for the five ALSEP systems presently active on the moon. The main interest is centered on the turn-off sequence, for experiments and ...
  • Apollo 15 Lunar Surface Magnetometer failure 
    Perkins, Derek. (Bendix Aerospace Systems Division, 1974)
    The LSM experiment data output became invalid at 15.07.33 hours on 10 December 1973. The data indicated "all ones". There have been spasmodic attempts by the experiment to output data since the original failure occurred, ...
  • Apollo 17 LACE background noise anomaly 
    Perkins, Derek. (Bendix, Aerospace Systems Division, 1973)
    The Lunar Atmospheric Composition Experiment (LACE) has experienced a zero offset condition in the low and mid mass channels of the science data since the experiment was first initialized on the moon. The cause of the ...
  • Apollo 17 LEAM temperature slope anomaly 
    Perkins, Derek. (Bendix, Aerospace Systems Division, 1973)
    The Lunar Ejecta and Meteorites Experiment (LEAM) temperature profile, during the 8th lunation of Apollo 17 ALSEP, indicated an apparent unusually rapid rise in temperature from 176 F. to 179 F. This rise was reported as ...
  • Evaluation of systems engineering approaches : (preliminary report) 
    Perkins, Derek. (Bendix, Aerospace Systems Division, 1974)
    This technical memorandum discusses the theoretical aspects of Systems Management, reviews the Systems Engineering approach used on the ALSEP program and concludes with recommendations for future programs.
