Courier

  1960-013


Courier was the first satellite to demonstrate active repeater communications in orbit. The Courier program was transferred from ARPA to the Dept. of the Army on 1960 Sep 15.

Mass was 225 kg. 

The second burn would have given a dV of about 0.36 km/s, so SECO-1 orbit probably had a somewhat negative perigee.
