1965-081A
The first POGO (Polar Orbiting Geophysical Observatory) was launched by Thrust Augmented Thor Agena D from Vandenberg on 1965 Oct 14. The orbit was 104.4 min, 415 x 1517 km x 87.4 deg. This orbit was significantly higher than the planned 97.33 min, 333 x 932 km x 86.0 deg one beacuse of a radio guidance failure. Attitude control was again lost early in the mission, on Oct 23, and the satellite was declared a failure. Nevertheless it sent back data until 1967 Nov 1 when it was shut down. It was reactivated for two weeks in 1968 Feb, then put on standby until 1971 Nov 1. The satellite reentered on 1981 Sep 17.
