The Spectroscopy of Plasma Evolution from Astrophysical Radiation (SPEAR) mission has observed far ultraviolet emission from the interstellar medium. Emitting species, such as HeII, CIII, CIV, OIII], OVI, SiIV and OIV, are detected in a variety of interstellar environments, as is molecular hydrogen fluorescence lines. We describe mission results including observations of far UV radiation from supernova remnants, super-bubbles, and the general interstellar medium. SPEAR (also known as FIMS) is the primary payload on STSAT-1 and was launched in late-2003. SPEAR performs spectral imaging of diffuse far-ultraviolet emission (900-1150 Å, 1350-1730 Å, resolution ~ 500) with a large field of view (4.5' x 4.5 deg & 7.5 deg, resolution 10').
The SPEAR UCB effort is funded in part by the NASA Research Carriers Grant NAG5-5335. The STSAT-1 Mission is funded by the Korea Ministry of Science and Technology.
