The Lunar Gateway is a planned space station that will orbit the Moon. It is being developed by NASA and several international partners, including the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), and the Canadian Space Agency (CSA).

The Gateway is intended to serve as a stepping stone for deep space exploration, including missions to Mars and beyond. It will provide a staging point for astronauts to live and work, conduct scientific research, and prepare for longer-duration missions.

Construction of the Gateway is expected to begin in the 2020s, with the first components launching in 2024. The station will be assembled in orbit around the Moon, and will be able to accommodate a crew of four astronauts.

The Gateway will also serve as a platform for lunar surface missions, using a lunar lander vehicle to transport astronauts to and from the lunar surface.

In addition to its scientific and exploration benefits, the Gateway is also expected to have economic and diplomatic implications. It will provide opportunities for international cooperation and collaboration, and could pave the way for commercial space activities beyond low Earth orbit.
