A scale model of a satellite was tested in a large vacuum facility under electron bombardment and vacuum ultraviolet radiation to investigate the charging of dielectric materials on curved surfaces. The model was tested both stationary and rotating relative to the electron sources as well as grounded through one megohm and floating relative to the chaw ber. Surface potential measurements are presented and compared with the predictions of computer mo.lelling of the stationary tests. Uischarge
