If funded by the Russian space agency Roscosmos, it would be developed by the Russian Space Research Institute and NPO Lavochkin, based on Fobos-Grunt technology.〔(Phobos-Grunt prepares for launch ). ATO - 16 August 2011.〕
Designs show a dome-shaped lander would separate from the orbiter and would enter the Martian atmosphere protected within an inflatable rubber braking cone and fire rockets for the final stage.〔(''Russian Space Probes: Scientific Discoveries and Future Missions'' ). By Brian Harvey, Olga Zakutnyaya. (p 475)〕 Once a robotic arm selects and retrieves the samples (mass about ),〔(Roscosmos - Space missions ) ''Published by The Space Review'' (page 9) on 2010〕 a small rocket in the top of the lander would blast the ascent vehicle for rendezvous and docking with the orbiter for the soil sample transfer into the return vehicle.
