Summary

FUSE 1, also known as FUSE, is an astronomy satellite designated by NORAD as CAT ID 25791 and launched on June 24, 1999, from the Air Force Eastern Test Range SLC17A using a Delta 7320-10 launch vehicle. It was manufactured by OSCG for GSFC (Goddard Space Flight Center) and has dimensions of 5.5 meters in length, 1.2 meters in diameter, and a span of 6 meters. The satellite's dry mass is 1130 kg, the same as its launch mass. FUSE is configured with a MidStar design, shaped like a box with two panels, and it carries a Far UV Spectroscopy Explorer (FUV telescope and spectrometer) for astronomy and far-UV spectroscopy purposes. Power is supplied by two deployable solar arrays and batteries. The satellite's mission was expected to last three years.
