The Deep Space Habitat (DSH) is a series of concepts by NASA that would be used to support crewed exploration missions to the Moon, asteroids, and eventually Mars.[1]


Since 2012, numerous iterations of large lunar and Mars transport habitats have been conceived in previous studies to be launched with the upcoming Space Launch System (SLS),[2][3] and are intended to also be compatible with the Orion capsule. Variations of the designs would be used for the Lunar Gateway and the Deep Space Transport.[2]

Early preliminary concepts considered 60-day and 500-day mission configurations, composed of International Space Station-derived hardware, the Orion crew capsule and various support craft.[4] The habitat would be equipped with at least one International Docking System Standard (IDSS) docking system. Developing a deep space habitat would allow a crew to live and work safely in space for about one year on missions to explore cislunar space, Mars, and some near-Earth asteroids.

In 2015 NASA funded studies for several types of deep space habitat concepts under the Next Space Technologies for Exploration Partnerships (NextSTEP).[5] Lockheed Martin, the main contractor of the Orion capsule, has also produced in 2018 a Deep Space Habitat concept.[6] These concept studies will help NASA decide on a final design for the habitat element for the Lunar Gateway with a contract potentially to be awarded in fiscal year 2019.[7]
