Named for Nobel laureate physicist
Holly Compton, the
Gamma Ray Observatory (CGRO) Satellite was launched in April of 1991
aboard the Space Shuttle Atlantis.
CGRO's mission is to explore the Universe at gamma-ray energies.
The massive space based observatory is seen here held upright in the

CGRO has been operating successfully since, providing the
first all-sky survey at gamma-ray energies
along with exciting new observations of the
and gamma-ray bursts.
