CRRES (Combined Release and Radiation Effects Satellite) was launched July 21, 1990 into a geosynchronous transfer orbit, with apogee at geosynchronous orbit (6.6 RE), perigee at 300 km, and an inclination of 18 degrees relative to the equatorial plane. CRRES carried a wide range of particle detectors as well as a very accurate and highly developed electric field instrument.
CRRES was active for 16 months and the observations it made revolutionized the study of the earth’s radiation belts and our understanding of the magnetosphere’s response to geomagnetic storms.
