Prognoz, also known as SO (Solar Object, first three satellites), SO-M (SO-modified, next seven satellites), and SO-M2 (last two satellites, also known as Interball), was a Soviet scientific research satellite programme. Twelve Prognoz satellites were launched between 14 April 1972, and 29 August 1996, by Molniya-M carrier rockets. The satellites were placed in high Earth orbits. The first ten Prognoz satellites were launched from Site 31/6 at the Baikonur Cosmodrome, and the last two from Site 43/3 at the Plesetsk Cosmodrome.[1][2][3]
The satellites were primarily used for Solar research; however, the later satellites were used for other kinds of research, including research into the Big Bang theory, and Earth's magnetosphere.[4] The tenth satellite was used as part of the Interkosmos programme.
