The Small Astronomy Satellite 2 (SAS-2)

The second NASA Small Astronomy Satellite (SAS-2)
was dedicated to gamma-ray astronomy in the energy range above 35 MeV. SAS-2
was launched on 1972 November 15 and began operations on 1972 November 19.
On 1973 June 8, a failure of the low-voltage power supply ended the collection
of data.
