Satellite television C. Clarke proposed a worldwide communications system which would function by means of three satellites equally spaced apart in earth orbit. This was published in the October 1945 issue of the Wireless World magazine and won him the Franklin Institute's Stuart Ballantine Medal in 1963. The first public satellite television signals from Europe to North America were relayed via the Telstar satellite over the Atlantic ocean on 23 July 1962, although a test broadcast had taken place almost two weeks earlier on 11 July.

Defense Meteorological Satellite Program P-698BH was used concurrently with P-35 from June 1962 and P-35 became P-417 in October 1962. The designation DMSP-1 (Defense Meteorological Satellite Program Block 1) was retroactively assigned to these satellites. The DSAP-2 (Defense Satellite Application Program Block 2) satellites series consisted of three modified DSAP-1 satellites, retaining the shape and dimension of the earlier series, featuring improved infrared radiometers. The designation DMSP-2 (Defense Meteorological Satellite Program Block 2) was retroactively assigned to these satellites. The single DSAP-3 (Defense Satellite Application Program Block 3) was a modified DSAP-2 satellite to provide experimental tactical access to weather data, for which a
