Magion (derived from 'magnetosphere' and 'ionosphere') were five satellites for magnetospheric research, launched by Czechoslovakia and later the Czech Republic in cooperation with the Soviet Union and later Russia between 1978 and 1996. They were used for measuring the properties of Earth's magnetic field and the plasma environment around the planet. Each Magion satellite collaborated in a two point system with another satellite launched on the same launch vehicle. Magion 1, 2, and 3 were part of the Interkosmos programme and Magion 4 and 5 were part of the Interball programme. Magion 1 was the first Czechoslovak satellite and Magion 4 was the first Czech satellite. All Magion satellites were launched from the Plesetsk Cosmodrome.
