An X-ray astronomy satellite that surveyed the sky in the 0.2 keV–10 MeV energy band, providing nearly constant monitoring of X-ray sources near the ecliptic poles. More detailed studies of a number of objects were made through pointed observations lasting typically 3–6 hours. The spacecraft remained active until Jan 9, 1979.
