The Third Small Astronomy Satellite (SAS-3)
The third US Small Astronomy Satellite (SAS-3) was launched in May 1975, with 3 major scientific objectives: 1) determine bright X-ray source locations to an accuracy of 15 arcseconds; 2) study selected sources over the energy range 0.1-55 keV; and 3) continuously search the sky for X-ray novae, flares, and other transient phenomena. It was a spinning satellite with pointing capability.
Mission CharacteristicsLifetime : May 1975 - Apr 1979
Energy Range : 0.1-60 keV
There are four X-ray experiments on SAS-3 that all used proportional counters as detectors with different collimating system. The experiments were not co-aligned.
