Mission Details
PPE & HALO
NASA has selected SpaceX to provide launch services for the agency’s Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO), the foundational elements of the Gateway. As the first long-term orbiting outpost around the Moon, the Gateway is critical to supporting sustainable astronauts missions under the agency’s Artemis program.
The PPE is a 60-kilowatt class solar electric propulsion spacecraft that also will provide power, high-speed communications, attitude control, and the capability to move the Gateway to different lunar orbits, providing more access to the Moon’s surface than ever before.
The HALO is the pressurized living quarters where astronauts who visit the Gateway, often on their way to the Moon, will work. It will provide command and control and serve as the docking hub for the outpost. HALO will support science investigations, distribute power, provide communications for visiting vehicles and lunar surface expeditions, and supplement the life support systems aboard Orion, NASA’s spacecraft that will deliver Artemis astronauts to the Gateway.
