The SPSR provides an in-space inspection instrument for non-destructive, quantitative engineering evaluation of spacecraft exterior surfaces. The SPSR measures total hemispherical reflectance as an indication of the effects of the space environment on materials such as thermal coatings, viewing windows, reflectors, solar power systems, etc. The SPSR will provide valuable data for determining how materials degrade when exposed to the space environment within the Shuttle/Mir implementation framework. The SPSR was transported to the Russian Mir Space Station during the STS-86 mission. The SPSR was returned to earth at the conclusion of the STS-89 mission.
