MAGION 2

Magion 2

MAGION-2 S/C was manufactured as the subsatellite of the ACTIVE S/C (INTERCOSMOS-24) and as the first subsatellite of a series of in- ternational scientific projects ACTIVE, APEX, INTERBALL.

As opposed to the MAGION-1 this S/C series with weight up to 65 kg has the form of a simmetrical polyhedron, has a set of folding booms for sensors , has digital system of data collection and has a gasjet propulsion engine. The scientific goal of the subsatellite of the ACTIVE project was to investigate space structure of physical phenomena which accompany plasma injection and to investigate powerful ULF emission into the magnetosphere as in a near (up to 10 km) zone , as well as in middle and far zones of the main S/C on which active injecting devices were mounted.
