COS-B - Overview
The COS-B Team at the Launch
Cos-B was launched on 9 August 1975. Its scientific
mission was to study in detail the sources of extra-terrestrial
gamma radiation at energies above about 30 MeV. The principal
- Study spectrum and distribution of galactic gamma rays
- Flux and distribution of extragalactic gamma-ray emission
- Study known point sources
- Search for new point sources

The originally foreseen duration of the mission
was two years, but in fact Cos-B was finally switched off on 25th
April 1982, having functioned successfully for 6 years and 8 months.
During this time an extensive survey of the Galaxy was made in
the energy range 50 MeV to 5 GeV.
