Polar Code Development,
S-CUBED LA JOLLA CA
Possible charging of large space structures in polar orbit has been examined analytically for simple spherical objects. The major questions of the probability of such events and the magnitude of charging given a particular vehicle in a specified auroral flux remain unanswered. The POLAR code is being developed to address the latter question. This paper outlines the physical models being incorporated in the program and the status of the code development. The phenomena of charging may be divided into three processes 1 the accumulation of charge on the object resulting from collection of charged particles from the space environment 2 the resultant change in overall and differential potentials on the vehicle and 3 the formation of a sheath and wake due to the presence of a charged object.
