Notional MADV on the surface of Mars (Credit: Lockheed Martin)by Marcel F. Williams At the 68th International Astronautical Congress, held in Australia last September, Lockheed Martin unveiled a remarkable new extraterrestrial spacecraft concept. The single staged space vehicle would be capable of landing either unmanned or crewed on the surfaces of the Moon or Mars. The MADV (Mars Ascent/Descent Vehicle) would be a propellant depot dependent spacecraft fueled with liquid oxygen and liquid hydrogen. And the MADV would be capable of transporting four member crews to the surfaces of the Moon or Mars. MADV (Mars Ascent/Descent Vehicle)Propellant: 80 tonnes of LOX/LH2 Inert weight: 30 tonnes Engines: 6 RL-10 enginesMaximum delta v capability: 6.0 km/sCrew: Up to four astronautsNotional MADV on the polar surface of the Moon (Credit: Lockheed Martin)After landing on the lunar or martian surface, crews would utilize an electric powered lift located on the vehicle's leeward side to access the surface from the pressurized crew cabin. Located between its six RL-10 engines, near the bottom of the vehicle, a retractable equipment lift would be lowered to deploy mobile vehicles and other equipment for use on the surface. However, the MADV's high delta-v capability (6 km/s) could also allow ...
