Also a dedicated launch with several units from low Earth orbit is under study.[1] Most of the Mars MetNet landers would be deployed to Mars separately a few weeks prior to the arrival to Mars to decrease the amount of required fuel for deceleration maneuvers. The satellite platform would then be inserted to an orbit around Mars and the last few Mars MetNet impact landers would be deployed to the Martian surface form the orbit around Mars to be able to land on any selected areas of the Martian surface in a latitude range of +/- 30 degrees for optimal solar panel efficiency.[1][2] A sounder on board the orbiter would perform continuous atmospheric soundings, thus complementing the in situ observations.
