The HEAO-3 Satellite
The HEAO-3 satellite carried three high-energy-astrophysics instruments, one instrument surveying the sky in hard X-rays and gamma rays, and two measuring the composition of cosmic rays. The High Resolution Gamma-Ray Spectrometer Experiment built by the Jet Propulsion Laboratory was the largest germanium spectrometer placed in orbit at that time. The cosmic-ray instruments, one built by a Danish-French collaboration and the other built as a collaboration among Washington University in St. Louis, Caltech, and University of Minnesota were the largest cosmic-ray detectors to have flown in space.
