A comparitive investigation concerning the spatial distribution of ions in the wake of small bodies was conducted using the theoretical wake models of Call (1969) and Parker (1976). Results for bodies with RD = 2 and RD = 5 (where RD = R0/&lgr;D,R0 is radius of the body, and &lgr;D is ambient Debye length), with a Te equal to the ambient electron temperature (e and k are electronic charge and Boltzmann's constants, respectively), and for the ionic Mach numbers S = 2,4,6,8 are presented. Since the main physical difference between the models is in the consideration of the thermal motion of ions (Parker) versus ignoring this component (Call), a comparison between the models yields the quantitive significance of this component in determining the distribution of ions in the wake of artificial satellites. The application of this result to future experiments to be conducted on board the Spacelab and for any other large space platform in the area of space plasma physics is mentioned.
