    Pepper, Brian J.; Yee, Karl Y.; Soibel, Alex; Fisher, Anita M.; Keo, Sam A.; Khoshakhlagh, Arezou; Gunapala, Sarath D. (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2019, 2019-04-14)
  • Gaseous discharge plasmas produced by high energy electron-irradiated insulators for spacecraft 
    Frederickson, A.; Benson, C.; Cooke, E. (2000-12)
    High-energy electron irradiation of insulators in vacuum causes both internal regions and surfaces of insulators to achieve high (negative) static voltage relative to nearby ground. Occasional spontaneous discharges inject ...
  • GAT/DeLiTe: An Autonomous System for Complete Micro-Gyroscope Characterization 
    Evans, C.; Gutierrez, R. (2000-03-18)
    The advancement of the MEMS micro-gyroscope development effort at the Jet Propulsion Laboratory has necessitated the production of autonomous test equipment.
  • Gateway Gravity Testbed (GGT)

  • GAuche-Ethyl Alcohol: Laboratory Assignments and Interstellar Identification 
    Pearson, J. C.; Sastry, K. V. L. N.; Herbst, Eric; De Lucia, Frank C. (1996)
    Ethyl alcohol (ethanol) is known to possess a pair of closely-spaced excited torsional substates (gauche +, gauche -) at an energy of approximately 57 K above the ground (trans) torsional substrate. We report an extended ...
  • Gaussian Mixture Models for Temporal Depth Fusion 
    Cigla, Cevahir; Brockers, Roland; Matthies, Larry (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2017, 2017-03-27)
    Sensing the 3D environment of a moving robot is essential for collision avoidance. Most 3D sensors produce dense depth maps, which are subject to imperfections due to various environmental factors. Temporal fusion of depth ...
  • GCM simulations of the tropical hydrogen distribution observed by Mars Odyssey 
    Mischna, Michael A.; Richardson, M. I. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2005., 2005-03)
    The age and nature of the tropical hydrogen deposits on Mars remain uncertain. Competing theories sugges that the deposits are composed of either ancient, hydrated minerals or recently emplaced water ice. We use the GFDL ...
  • GCMS/Montgolfiere Micromission at Mars 
    Jones, J.; Rivera, J.; Mahaffy, P.; Gorevan, S. (2000-09-15)
  • GEANT4 and secondary particle production 
    Patterson, Jeff (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2005., 2004-09-22)
    GEANT 4 is a Monte Carlo tool set developed by the High Energy Physics Community (CERN, SLAC, etc) to perform simulations of complex particle detectors. GEANT4 is the ideal tool to study radiation transport and should ...
