The Extreme Ultraviolet Explorer (EUVE) spacecraft is expected to re-enter the Earth?s atmosphere sometime on Thursday morning. Although they don?t know where or when it will crash – as far South as Brisbane, Australia, and as far North as Orlando, Florida – NASA believes that most of the spacecraft will be destroyed on re-entry with some pieces crashing into the ocean. Unlike many large spacecraft, the EUVE wasn?t built with a propulsion system to control its crash location. During its eight years in orbit, the EUVE observed over 1,000 objects in the extreme ultraviolet spectrum.
