Deep Space Transport

The Deep Space Transport (DST), also called Mars Transit Vehicle,[6] is a crewed interplanetary spacecraft concept by NASA to support science exploration missions to Mars of up to 1,000 days.[4][2][7] It would be composed of two elements: an Orion capsule and a propelled habitation module.[3] As of late 2019, the DST is still a concept to be studied, and NASA has not officially proposed the project in an annual U.S. federal government budget cycle.[5][8][9] The DST vehicle would depart and return from the Lunar Gateway to be serviced and reused for a new Mars mission.
