Abstract:

Atomic oxygen is the predominant component and one of the most severe environment factors. In low earth orbit (LEO), it may cause severe erosion of spacecraft materials. The measurement of atomic oxygen flux is the foundation in the study of atomic oxygen effects, an important parameter for quantifying the exposure level of atomic oxygen and evaluating the atomic oxygenduration lifetime of spacecraft components and materials in LEO.

Key words: atomic , oxygen,  , flux,  , measurement , method,  , ground-based , facility
