Paper Abstract

In this study we report on the effects of space flight on the reflectance properties of PTFE (polytetrafluorethylene) and aluminum diffuser samples that were flown along with the Shuttle Solar Backscatter Ultraviolet experiment on STS-43, STS-45, and STS-56. These initial experiments showed good stability in the visible and near infrared with some degradation in the ultraviolet which vary from flight to flight which could be attributed to different amounts of contamination levels. This paper reports on the diffuser material processing, the space environment experienced, and the results of the reflectance measurements and the surface chemical analysis before and after flight.
