Abstract:

Experimental data were obtained from the Explorer VIII satellite on five parameters pertinent to the problem of the interaction of space vehicles with an ionized atmosphere. The five parameters are photoemission current due to electrons emitted from the satellite surfaces as a result of solar radiation electron and positive ion currents due to the diffusion of charged particles from the medium to the spacecraft the vehicle potential relative to the medium, and the ambient electron temperature. Included in the experimental data is the aspect dependence of the photoemission and diffusion currents. On the basis of the observations, certain characteristics of the satellites plasma sheath are postulated. Author
