European space mission
COS-B
was the first
European Space Research Organisation
(ESRO) mission to
study cosmic gamma ray sources
. COS-B was first put forward by the European scientific community in the mid-1960s and approved by the ESRO council in 1969. The mission consisted of a satellite containing gamma-ray detectors, which was launched by
NASA
on behalf of the
ESRO
on 9 August 1975. The mission was completed on 25 April 1982, after the satellite had been operational for more than 6.5 years, four years longer than planned and had increased the amount of data on gamma rays by a factor of 25. Scientific results included the
2CG Catalogue
listing around 25 gamma ray sources and a map of the
Milky Way
. The satellite also observed the
X-ray binary
Cygnus X-3
.
