Abstract:

This research effort dealt with environmental studies in magnetospheric physics that affect large spacecraft in space. The objectives were in four areas development of computerized models of magnetospheric particle and field conditions, development of empirical models of precipitating particles distributions at geosynchronous altitude, plasma-beam studies and spacecraft charging, and development of a shuttle code to model electrical potentials and currents under various magnetospheric conditions. Scientific results and accomplishments have been reported in published journal articles and AFGL reports. The contents of this Final Report include a documentation of the publications and detailed status reports of ongoing work. The latter include a description of the high energy radiation belt model developed for steady state and time dependent conditions, the development of a model of the poleward boundary of precipitating auroral ions, the study of ion signatures in the polar rain, and the relationship between the diffuse aurora and the near-earth plasma sheet electrons.
