FUSE is a NASA-supported astronomy mission launched on June 24th 1999 with a mission to explore the Universe using the technique of high-resolution spectroscopy in the far-ultraviolet spectral region.
The FUSE telescope will probe many of the surrounding stars and nebulae using a UV telescope.
Where exactly are we, and where will FUSE go?
