SURFACE-PARTICLE-INTERACTION MEASUREMENTS USING PADDLEWHEEL SATELLITES

Abstract

Surface-particle-interaction measurements have been carried out by utilizing the torque and drag force on two paddlewheel satellites with perigee altitudes between 250 and 300 km. The angular distribution of the re-emitted molecules was inferred to be nearly diffuse, and the accommodation coefficients were between 0.65 and 0.9. A proposed satellite experiment, Project ODYSSEY, is described in which the surface-particle-interaction and atmospheric parameters will be measured with much improved accuracy.
