Associated space launch
FUSE (Far Ultraviolet Spectroscopic Explorer) represented the next generation, high-orbit, ultraviolet space observatory covering the wavelength range of 90.5-119.5 nm. The primary objective of FUSE was to use high-resolution spectroscopy at far ultraviolet wavelengths to study the origin and evolution of the lightest elements (hydrogen and deuterium) created shortly after the Big Bang, and the forces and processes involved in the evolution of galaxies, stars and planetary systems.
FUSE 1 was lifted into orbit during the mission ‘Delta II | FUSE’, on board a Delta II space rocket.
The launch took place on June 24, 1999, 3:44 p.m. from Space Launch Complex 17A.
