Interkosmos 1 [Yuzhnoye]

The Interkosmos DS-U3-IK series consisted of six missions in to measure solar radiation and its effect on the atmosphere. They were conducted by Interkosmos, an international cooperation of socialist countries.

The satellites were based on Yuzhnoye's DS-U3 bus. The sun-pointed satellites were solar powered by eight deployable solar arrays. These satellites carried a suite of east European experiments to study solar ultraviolet and X-ray effects on upper atmosphere.

Interkosmos 1 was launched on 14 October 1969 on a Kosmos-2 rocket from the Plesetsk cosmodrome.

Interkosmos 4 was launched on 14 October 1970 on a Kosmos-2 rocket from the Kapustin Yar cosmodrome.

Interkosmos 7 was launched on 30 June 1972 on a Kosmos-2 rocket from the Kapustin Yar cosmodrome.

Interkosmos 11 was launched on 17 May1974 on a Kosmos-3M rocket from the Kapustin Yar cosmodrome.

Interkosmos (14) was launched on 3 June 1975 on a Kosmos-3M rocket from the Kapustin Yar cosmodrome, but failed to reach orbit.

Interkosmos 16 was launched on 27 July1976 on a Kosmos-3M rocket from the Kapustin Yar cosmodrome.
