Summary
The Combined Release and Radiation Effects Satellite (CRRES) was launched into
a geosynchronous transfer orbit (GTO) for a nominal three-year mission to
investigate fields, plasmas, and energetic particles inside the Earth's
magnetosphere. As part of the CRRES program the SPACERAD (Space Radiation
Effects) project, managed by Air Force Geophysics Laboratory, ... investigated the
radiation environment of the inner and outer radiation belts and measured
radiation effects on state-of-the-art microelectronics devices. Other
magnetospheric, ionospheric, and cosmic ray experiments were also included
onboard CRRES and supported by NASA or the Office of Naval Research. The
chemical release project was managed by NASA/MSFC and utilized the release of
chemicals from onboard cannisters at low altitudes near dawn and dusk perigee
times and at high altitudes near local midnight. The chemical releases were
monitored with optical and radar instrumentation by ground-based observers to
measure the bulk properties and movement of the expanding clouds of
photo-ionized plasma along field lines after the releases occurred. In order to
study the magnetosphere at different local times during the mission, the
satellite orbit was designed to precess with respect to the earth-sun line such
that the local time at apogee decreased by 2.5 minutes/day from 08:00 (LT) just
after launch and returned to this position in nineteen month cycles. The CRRES
spacecraft had the shape of an octagonal prism with solar arrays on the top
side. The prism is 1 m high and 3 m between opposite faces. Four of the eight
compartments were for the chemical canisters and the other four housed the
SPACERAD and other experiments. The spacecraft body was spun at 2.2 rpm about a
spin axis in the ecliptic plane and kept pointed about 12 degrees ahead of the
Sun's apparent motion in celestial coordinates. Pre-launch and in-flight
operations were supported by the Space Test and Transportation Program Office
of the U.S. Air Force Space Division. Contact with the CRRES spacecraft was
lost on October 12, 1991 and was presumed to be due to onboard battery failure.

CRRES data sets consists of attitude and ephemeris data, magnetic field data,
and energetic particle data.
