The TAIL PROBE with its subsatellite was launched on 3 August 1995 to the elongated elliptical orbit with the inclination of 65 degrees and apogee of 200 000 km. These satellites study the interactions of the Solar Wind with the Magnetopause and the outer regions of the magnetosphere. Specific aims is to study the active plasma processes within the tail where powerful currents, substorms and other large-scale non-linear magnetospheric phenomena originate. The separation in this pair will change from less than 100 km, allowing to study the small-scale wave and plasma structures at the boundaries, till about 1-2 RE (the Earth's radii) to study large plasma structures in the tail.
