1990-065A
The Combined Release and Radiation Effects Satellite, CRRES, was a joint project between the US Air Force Geophysics Lab (AFGL) and NASA carried out under the Space Test Program as mission P86-1. The original plan was for a Shuttle launched craft which would spend several months in low orbit before moving to highly elliptical orbit. The mission was rescoped to an Atlas launch and the low orbit phase was dropped. Two chemical release canisters were offloaded to the Pegsat mission. The spacecraft was built by Ball Aerospace.
CRRES was launched on 1990 Jul 25 by Atlas Centaur AC-69. The Centaur used RL10A-3-3A engines and the 14-foot payload fairing and a type B payload adapter. The chemical release phase of the mission lasted until Aug 1991. The NASA canisters were ejected and drifted 3 km away from CRRES before the chemical release wastriggered. After the chemical releases CRRES continued its radiation exposure and magnetospheric studies for a few months before the spacecraft's life was cut short by a power system failure.
