The Lunar Gateway, or simply Gateway, is a planned space station which is to be assembled in orbit around the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts as part of the Artemis program. It is a multinational collaborative project: participants include NASA, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the Mohammed Bin Rashid Space Centre (MBRSC). The Gateway is planned to be the first space station beyond low Earth orbit. However, the Trump administration has called for ending the Gateway program in its 2026 budget proposal.
The science disciplines to be studied on the Gateway are expected to include planetary science, astrophysics, Earth observation, heliophysics, fundamental space biology, and human health and performance. As of April 2024, construction is underway of the initial habitation and propulsion modules. The International Space Exploration Coordination Group (ISECG), which is composed of 14 space agencies including NASA, has concluded that Gateway systems will be critical in expanding human presence to the Moon, to Mars, and deeper into the Solar System.
The project is expected to play a major role in the Artemis program after 2026. NASA's Budget for FY 2025 included $817.7 million for the project. While the project is led by NASA, the Gateway is meant to be developed, serviced, and used in collaboration with the CSA, ESA, JAXA, and commercial partners. It will serve as the staging point for both robotic and crewed exploration of the lunar south pole and is the proposed staging point for NASA's Deep Space Transport concept for transport to Mars.
