s launched in 1962. Two different types of satellite, 1MS and 2MS were used, with two satellites of each type being launched. Three of the satellites were operated successfully, however one of the 1MS satellites was lost in a launch failure. The three that reached orbit received Kosmos designations.

MS satellites were developed by OKB-1
