Part of the Gateway External Robotics Systems (GERS) provided by CSA, Canadarm3 is a robotic system that will use cutting-edge software to perform Gateway tasks. The system will help maintain, repair and inspect Gateway, capture visiting vehicles, help astronauts during spacewalks, and enable science in Gateway’s lunar orbit.

The Gateway space station hosts the Orion spacecraft in a polar orbit around the Moon, supporting scientific discovery on the lunar surface during the Artemis IV mission.

jsc2024e064820 -- Stephanie Dudley, Gateway’s mission integration and utilization manager, sits inside a high-fidelity HALO (Habitation and Logistics Outpost) mockup at NASA’s Johnson Space Center. HALO is one four Gateway modules where astronauts will live, conduct science, and prepare for missions to investigate the lunar South Pole region. Dudley works with NASA’s partner space agencies and academia to identify science opportunities on Gateway.

Hardware for the Gateway space station’s Power and Propulsion element, including its primary structure and fuel tanks ready for assembly, are shown at Maxar Space Systems in Palo Alto, California.

The Lunar Gateway Launch, mapped. Gateway's first elements, the Power and Propulsion Element and HALO (Habitation and Logistics Outpost), will launch together to lunar orbit, where they’ll set the stage for Artemis IV: the first Gateway assembly mission. During this milestone mission, the Artemis IV crew will deliver the European Space Agency's Lunar I-Hab, dock it to HALO, and enter the space station for the very first time. NASA is currently targeting a 2027 launch for HALO and the Power and Propulsion Element. This timeline allows for the roughly year-long journey to lunar orbit and ensures everything is in place ahead of Artemis IV.

Gateway's International Habitat (I-Hab) module, provided by ESA, is one of two of the space station's habitation modules in addition to HALO. Astronauts will live, conduct science, and prepare for lunar surface missions inside I-Hab and HALO.
