Abstract

Organic molecules are the main contamination source of space payloads on orbit, and they need to be removed as much as possible on ground phase. In this paper, based on the vacuum outgassing rules of nonmetal materials and the outgassing methods of satellite materials, a simple, high-efficiency, low-cost test method for outgassing of space contamination sensitive instruments was proposed. In the method, the requirements of test equipment, test conditions, terminal criteria, and outgassing effect evaluation were presented. Using this method, several common nonmetal materials were tested for outgassing. The results show that the method is efficacious.
