Far Ultraviolet Spectroscopic Explorer
(early 2000s space telescope for short-wavelength ultraviolet)
Far Ultraviolet Spectroscopic Explorer (FUSE)
was a NASA Explorers Program
space-based telescope for far ultraviolet spectrography,
launched in 1999 into Earth orbit and operated until 2007.
I believe it is still in orbit, though not in use.
Among its goals were determination of the
deuterium present in the universe through its history.
