EOLE
Eole, originally FR-2, was known to NASA as CAS 1 (Cooperative Applications Satellite 1). The 84kg satellite was built by Aerospatiale. Eole relayed data from meteorological balloons released from Argentina. In 1980 the satellite was still in use for training tracking station operators. Eole is named after Aeolus, the wind god.
