Summary

Calculations of the spacecraft interaction with the low earth orbit space plasma environment are presented, based on two computer codes, MACH and POLAR. MACH is an inside-out particle tracking code which treats spacecraft in a cylindrically symmetric grid, while POLAR is fully three dimensional. The methodology of MACH is more fundamental than that of POLAR, and MACH is used for validating the physics of POLAR in regimes where there are no comprehensive theoretical of experimental results. POLAR and MACH solutions for the wake of a charged disk in MACH 4, 5, and 8 flow are compared.
