Extreme Ultraviolet Explorer (EUVE)

Launched in June 1992, the Extreme Ultraviolet Explorer (EUVE) conducted the first extreme ultraviolet (70-760 Angstroms) survey of the sky and subsequently began a Guest Observer Program of pointed spectroscopy that ended on January 31, 2001. The satellite had four photometric imaging systems and a three-channel EUV spectrometer. The imaging instruments were used to complete the sky survey; the spectrometers were used for the pointed spectroscopic programs, which collected data from over 350 unique astronomical targets.

EUVE re-entered the Earth's atmosphere on January 30, 2002.
