The Propulsion Bus Module of Gateway’s Power and Propulsion Element undergoes assembly and installations at Maxar Space Systems in Palo Alto, California.Maxar Space Systems NASA’s Artemis IV astronauts will be the first to inhabit the Gateway lunar space station, opening the door to greater exploration of the Moon and paving the way to Mars. Gateway’s Power and Propulsion Element, which will make the station the most powerful solar electric spacecraft ever flown, takes shape at Maxar Space Systems. In lunar orbit, Gateway will allow NASA to conduct unique science and exploration while preparing astronauts to go to the Red Planet.
Technicians install key hardware on the element’s Propulsion Bus Module following installation of both electric propulsion and chemical propulsion control modules. The image highlights a propellant tank exposed on the right, positioned within the central cylinder of the element.
The Power and Propulsion Element will launch with Gateway’s HALO (Habitation and Logistics Outpost) ahead of NASA’s Artemis IV mission. During Artemis IV, V, and VI, international crews of astronauts will assemble the lunar space station around the Moon and embark on expeditions to the Moon’s South Pole region.
The Power and Propulsion Element is managed out of NASA’s Glenn Research Center in Cleveland and built by Maxar Space Systems in Palo Alto, California.
Gateway is an international collaboration to establish humanity’s first lunar space station as a central component of the Artemis architecture designed to return humans to the Moon for scientific discovery and chart a path for the first human missions to Mars.

The unpiloted Roscosmos Progress spacecraft pictured on Aug. 13, 2024, from the International Space Station.Credit: NASA NASA will provide live launch and docking coverage of a Roscosmos cargo spacecraft delivering approximately three tons of food, fuel, and supplies for the crew aboard the International Space Station.
The unpiloted Roscosmos Progress 91 spacecraft is scheduled to launch at 4:24 p.m. EST, Thursday, Feb. 27 (2:24 a.m. Baikonur time, Friday, Feb. 28), on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.
Live launch coverage will begin at 4 p.m. on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.
After a two-day in-orbit journey to the station, the spacecraft will dock autonomously to the aft port of the Zvezda service module at 6:03 p.m. Saturday, March 1. NASA’s rendezvous and docking coverage will begin at 5:15 p.m. on NASA+.
The Progress 91 spacecraft will remain docked to the space station for approximately six months before departing for re-entry into Earth’s atmosphere to dispose of trash loaded by the crew.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human exploration of Mars.
