Explorer 12

  1961-020


The S-003 payload, also known as EPE-A (Energetic Particles Explorer A), was launched on 1961 Aug 15 by Delta from Cape Canaveral into a highly elliptical orbit with an apogee of 77000 km. Interestingly, it was the first satellite to be launched into an orbit with a period close to the geosynchronous period of 24 hours. Explorer XII transmitted until 1961 Dec 6 and reentered on 1963 Sep 27.

Mass was 38 kg. Size was 0.48m high 0.66m dia with a 0.81m magnetometer boom.

The prelaunch plan was a first perigee at 14N 49W and apogee at 12S 99W.
