Interkosmos 3, 5, 9, 10, 12, 13, 14 (DS-U2-IK)

Interkosmos 13

The Interkosmos DS-U2-IK series consisted of seven missions in to investigate the charged particle flows and the ionosphere. They were conducted by Interkosmos, an international cooperation of socialist countries.

The satellites were based on Yuzhnoye's DS-U2 bus. The satellites were solar powered. These satellites carried a suite of east European experiments to measure protons, electrons and alpha particles.

Interkosmos 3 was launched on 07 August 1970 on a Kosmos-2 rocket from the Kapustin Yar cosmodrome. It examined charged particle flows and the ionosphere. The payload consisted of East European experiments that studied protons, electrons and alpha particles.

Interkosmos 5 was launched on 2 December 1971 on a Kosmos-2 rocket from the Kapustin Yar cosmodrome. It measured the radiation levels in near-Earth space, investigated dipole corpuscular streams in near space in connexion with solar activity and investigation of the nature and spectrum of low-frequency electromagnetic oscillations in natural plasma. The satellite featured Czechoslovakian and Soviet instruments to investigate the effects of solar activity on near-Earth radiation.

Interkosmos 9, also called Kopernik 500, was launched on 19 April 1973 on a Kosmos-2 rocket from the Kapustin Yar cosmodrome. It Investigated solar radio-frequency radiation and the characteristics of the earth's ionosphere.

Interkosmos 10 was launched on 30 October 1973 on a Kosmos-3M rocket from the Plesetsk cosmodrome. Its purpose was to study geophysical phenomenes at high latitudes and to investigate the electromagnetic coupling of the earth's magnetosphere and ionosphere.

Interkosmos 12 was launched on 31 October 1974 on a Kosmos-3M rocket from the Plesetsk cosmodrome. The mission objectives were atmospheric and ionospheric research. It conducted a comprehensive investigation of the earth's atmosphere and ionosphere and of micrometeorite fluxes.

Interkosmos 13 was launched on 27 March 1975 on a Kosmos-3M rocket from the Plesetsk cosmodrome. it was focused on upper atmospheric experiments. The satellite conducted a study of dynamic processes in the earth's magnetosphere and polar ionosphere and investigation of low-frequency electromagnetic waves.

Interkosmos 14 was launched on 11 December 1975 on a Kosmos-3M rocket from the Plesetsk cosmodrome. This satellite conducted a study of low-frequency electromagnetic vibrations in the magnetosphere of the earth, of the structure of the ionosphere and of the intensity of micrometeorite fluxes.
