PATTERN OF THE DAY | ELEMENTS IN SPACE
CELEBRATING SPACE WEEK ‘Materials on International Space Station Experiment-8.’ July 12, 2011
The small circles are test beds for materials and computing elements attached to the outside of the ISS. These elements are being evaluated for the effects of atomic oxygen, ultraviolet, direct sunlight, radiation, and the extremes of heat and cold. Researchers hope the results will provide a better understanding of the durability of various materials and computing elements when they are exposed to the rigours of space environments and hope to incorporate what is learned into the design of future spacecraft.
