| Abstract: | This paper introduced the influence of the LEO(Low Earth Orbit) environments to spacecraft surface material and the evaluating technology about the lifetime of the spacecraft surface material in LEO.This work numerically simulate the action of atomic oxygen on polyimide with or without coated layer both in LEO and ground experiment environments. The results compare very well with the LDEF results. As a result, the present work provides a good guideline to the design of spacecraft. |
