Abstract: This paper introduces the influence of the LEO environments on spacecraft surface materials and the evaluating technology of lifetime of spacecraft surface materials in LEO.In this work,numerically simulate influence of atomic oxygen on polyimide with or without coated layer both in LEO and ground experiment environments.As a result,the present work provides a good guideline to the design of spacecraft.
