The Extreme-Ultraviolet Explorer (EUVE) was a spinning spacecraft designed to rotate about the earth/sun line. EUVE was a part of NASA's Explorer spacecraft series, and designed to operate in the extreme ultraviolet (EUV) range of the spectrum, from 70 - 760 Angstroms. This spacecraft's objective was to carry out a full-sky survey, and subsequently, a deep-survey and pointed observations. Science objectives included discovering and studying UV sources radiating in this spectral region, and analyzing effects of the interstellar medium on the radiation from these sources.
