Mars Base Camp
Mars Base Camp (MBC) is a crewed Mars laboratory orbiter concept under study commissioned by NASA from Lockheed Martin in the US. It would use both future and proven concepts as well as the Orion MPCV, also built by Lockheed Martin. The Mars Base Camp concept has been proposed to NASA as a possible version of the Deep Space Transport, a crewed interplanetary spacecraft to support science exploration missions to Mars of up to 1,000 days.
