Millimetron mission
Mission overview
Millimetron mission presupposing deployment of a cryogenic-cooled radio telescope of millimeter and infrared bands in a high-amplitude quasi halo orbit around Sun-Earth L2 point is scheduled for the beginning of 2020s. The project has been designed at the Astro Space Center of Lebedev Physical Institute, RAS. Spacecraft platform Navigator and other hardware is produced and assembled at NPO Lavochkin.

Stationkeeping impulses presented in green are multiplied by factor 10x9 in order to be noticable on the spacecraft trajectory plot. The original stationkeeping impulses have dimensions of 1 to 0.01 m/s. Particularity of this trajectory is that the first stationkeeping impulse is of 10 m/s range which made impulse vecotr overscaled compared to other vectors.
