Extreme Ultraviolet Explorer

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 has 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
