1968-014A
The OGO 5 payload was launched at 1306:01 on 1968 Mar 4 by an Atlas Agena D. OGO 5 had two 9m radio astronomy antennas. The satellite studied the plasmapause region of the magnetosphere. Agena 6503 delivered Orbiting Geophysical Observatory 5 into a 232 x 148228 km x 31.1 deg orbit and the satellite was operational on Mar 16. Attitude control failed on 1971 Aug 6 and the satellite was put on standby on 1971 Oct 8. 3 experiments were turned back on on 1972 Jun 1, and OGO 5 was finally decommissioned on 1972 Jul 14.
