Satellite Spacecraft Charging Control Materials.

Abstract : The feasibility of conductive adhesive techniques for the electrical interconnection of ITO-coated second surface mirrors has been studied. The good electrostatic performance and the durability of components combining ITO coated aluminized Kapton and aluminum straps by means of a silver loaded silicone have been confirmed by a prequalification program. The charge dissipation mechanisms for silica fabrics in a geosynchronous magnetic substorm environment have been studied by means of various sample configurations that have been tested under electron beam. Some recommendations have been given for a better use of silica fabrics as thermal control coatings in space. (Author)
