Misja Intercosmos-25

The Intercosmos-25 satellite with a Czech made sub-satellite was launched on the Earth’s orbit on December 18, 1991. Aboard the spacecraft were: an electron gun (6.2keV), a plasma gun (400eV), and a plasma diagnostics system. Another plasma diagnostics package was located on the sub-satellite. The main goal was to investigate the dynamics of an electron beam within an unconfined plasma system and the interaction of counter streaming plasma beams. Six instruments for plasma diagnostics provided by Poland were located on the spacecraft and sub-satellite.
