Gateway's ESPRIT Refueling Module, or ERM, will provide refueling capabilities for the space station, cargo storage, and windows for stunning views of the Earth, Moon and deep space. ERM will be delivered to Gateway by the crewed Orion spacecraft on the Artemis V mission after launching on an Space Launch System (SLS) Block 1B rocket.

This infographic shows each element of Gateway, humanity's first space station in lunar orbit as a vital component of the Artemis missions to return to the Moon for scientific discovery and chart the path for the first human missions to Mars.

The Gateway space station will be humanity's first space station around the Moon as a vital component of the Artemis missions to return humans to the lunar surface for scientific discovery and chart the path for the first human missions to Mars. Astronauts on Gateway will be the first humans to call deep space home during missions where they will use Gateway to conduct science and prepare for lunar surface missions.
