Magnetospheric Orbiter
Summary

|
Magnetospheric Orbiter |
The Magnetospheric Orbiter performs in-situ field, wave and particle research with the instruments listed below. The spacecraft spins at 15 rpm with its axis perpendicular to the equatorial plane. The orbit is polar and the period of 9.3 hours is a multiple of that of the planetary orbiter. The line of apsides lies in the equatorial plane, and the pericentre and apocentre cover the altitude range 400 - 12 000 km, which makes it possible to explore the magnetotail up to planetocentric distances of almost six planetary radii.
