Description The European-built Cupola was added to the International Space Station in 2010 and continues to provide the best room with a view anywhere. In addition to serving as an observation and european hit singles area when the crew operates the Station’s robotic arms, it also provides excellent views of Earth, celestial objects and visiting vehicles. Its fused-silica and borosilicate-glass windows, however, sometime suffer from impacts by tiny artificial objects: space debris.
