1962-056
Satellite DS-A1 No. 1 was launched on 1962 Oct 20 and was announced as carrying a Mayak ionospheric topside sounder beacon and instruments to study ion density and atmospheric density. In fact, the main purpose of the DS-A1 series was to measure the properties of high altitude nuclear explosions and artifical and natural radiation belts, similar to the US Starad and EPE-D satellites. Mass of the DS-A1 satellites was from 210 to 260 kg. DS-A1 was also considered an analog to Vela. Later, Uragan satellites carried nuclear explosion detection sensors.
DS-A1 was an ellipsoid with a mass of 220 kg.
