    Several years of work have combined plasma measurements in a laboratory Hall thruster and r-z numerical simulations with Hall2De to isolate the spatial variation of the anomalous collision frequency needed in Ohm’s law to ...
  • Lo, M. W. (1997-02-09)
    In recent years, halo orbits around the Sun-Earth Lagrange points, L1 and L2, have become extremely opular for NASA missions due to the ideal observation environment and low launch energy.
  • Lo, M.; Serban, R.; Petzold, L.; Koon, W.; Ross, S.; Marsden, J.; Wilson, R. (2000)
    This paper addresses the computation of the required trajectory correction maneuvers (TCM) for a halo orbit space mission to compensate for the launch velocity errors introduced by inaccuracies of the launch vehicle.
