The
Compton Gamma-Ray Observatory (CGRO)
The
Compton Gamma-Ray Observatory was launched April 7, 1991. It is the version
of the Hubble Space Telescope that detects gamma-ray emissions. Its mission
is to study gamma-ray emissions in not only our galaxy, but other galaxies beyond
ours, and to investigate how neutron stars and black holes change over time.
The Compton Observatory is expected to operate and provide scientists with information
for 10 years. In order to accomplish this goal, the probe will be reboosted
in 1997. Without this, the CGRO would fall back into the Earth's atmosphere
where it would burn up upon re-entry.
