NASA would launch the first element of a human-tended Lunar Orbital Platform-Gateway in 2022 under a proposed exploration plan that would make use of commercial and international partnerships.
A power and propulsion module would be followed soon afterward by habitation, airlock, and logistics modules. The gateway would serve as a base for astronauts to explore the moon for the first time since Apollo 17 lifted off from the surface in 1972.
