MS was a series of four Soviet satellites launched[1] in 1962. Two different types of satellite, 1MS and 2MS were used, with two satellites of each type being launched.[2] Three of the satellites were operated successfully, however one of the 1MS satellites was lost in a launch failure.[3] The three that reached orbit received Kosmos designations.[4]
MS satellites were developed by OKB-1, and used for technology demonstration and development.[5] They also carried payloads to investigate radiation and cosmic rays.
