The Space Gateway will be humanity's first spaceship, a crewed platform in deep space from which human exploration of the Solar System can set forth.
During the 2020s, the Space Gateway will be assembled and operated in the vicinity of the Moon, where it will move between different orbits and enable the most distant human space missions ever attempted. The Space Gateway will be a testing ground for the challenges of long-duration human missions in the environment of deep space.
The Space Gateway initiative is being led by the International Space Station partners: ESA, NASA, Roscosmos, JAXA, and CSA. Plans are currently at an early stage of definition and envision a power and propulsion system, a small habitat for the crew, a docking capability, an airlock, and logistics modules.
