Abstract : Studies in the field of space flight thermal radiation simulation to provide a system to compute real-time information about the intensity and distribution of thermal radiation fields illuminating a vehicle in space are presented. The details are limited to vehicles in near earth orbits, but the discussion is sufficiently generalized to indicate how transfer trajectories and alternate primary bodies may be incorporated. The time functions obtained may eventually control the sequencing of parameters in the Mark I aerospace environment simulator or at least provide an independent means to evaluate system performance when the simulator becomes operational.
