NASA's Fast Space Telescope fell out of orbit after 22 years of operation, burning up in the atmosphere, according to the agency's website. The spacecraft was launched into orbit in 2004. The main task of the telescopes was to detect gamma-ray bursts - intense emissions of gamma radiation resulting from large cosmic events, such as supernova explosions.
