AbstractSpace environment is a potential factor to affect the charging/discharging phenomena of spacecraft systems. However, no special attention has been paid for property changes of spacecraft materials during space exposure form the viewpoint of charging. Today, a circumstance on space environmental effect studies is changing due to the retirement of space shuttle. The space environmental effect on the solar cell materials will be evaluated in the new circumstances without using a space shuttle; sample return mission will be difficult to conduct. This situation is not only for solar cell materials, but also for other materials tests including thermal control materials. This paper describes the recent trend of space environmental effect studies on general materials both for flight and ground-based studies, which is prepared for the retirement of space shuttle. It should be stressed that the more precise ground-based exposure experiment technique has to be established for deep understanding of the space environmental effect on materials, especially for photovoltaic solar array systems.
