KRECHET AUTONOMOUS SPACE TUG.DU-802 PROPULSION SYSTEM

The Krechet Autonomous Space Tug (AST) has been developed for the Ukrainian-Russian LV Dnepr. It includes the principally novel supply system based on application of pneumatic pump unit (PPU). DU802 allows to ensure soft landing onto the Moon surface, takeoff from the Moon surface and lunar orbital injection.
