摘要: The continued presence and use of silicones on spacecraft in low Earth orbit (LEO) has been found to cause the deposition contaminant films surfaces which are also exposed atomic oxygen. composition optical properties resulting SiO(x)- based (where x is near 2) may be dependent upon relative rates arrival oxygen, silicone hydrocarbons. This paper presents results in-space contamination tests, ground laboratory simulation tests analytical modeling identify controlling processes that affect characteristics.
