The Gamma Ray Observatory (GRO) has been undertaken by NASA to make the next major thrust in high-energy astrophysics. The GRO will be flown in a circular orbit at an altitude of 400 km with an inclination of 28.5 degrees. The Shuttle will take the GRO to its nominal orbit altitude. The GRO will be removed and will ascend to 400 km using its own propulsion system. The GRO will record and transmit data to the Tracking and Data Relay Satellite, which will then relay the signal to ground. The GRO will consist of four separate instruments that collectively span the photon spectrum from 0.05 to 30,000 MeV, almost six decades in energy. The photon sensitivity over the entire six-decade range will be improved by more than an order of magnitude over the best previously flown instruments. Significant improvements in angular resolution will also be made.
