- The Deep Space Transport (DST), also called Mars Transit Vehicle is a crewed interplanetary spacecraft concept by NASA to support science exploration missions to Mars of up to 1,000 days. It would be composed of two elements: an Orion capsule and a propelled habitation module. As of April 2018, 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
- The DST vehicle would depart and return from the Lunar Orbital Platform-Gateway (LOP-G) to be serviced and reused for a new Mars mission.
