Gateway PPE & HALO - Space launch mission detailed information
Gateway PPE & HALO
31 DEC 2025
Launch Complex 39A
The Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO) are the foundational elements of NASA's lunar-orbiting space station "Gateway". 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. 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.
The Falcon Heavy is a variant of the Falcon 9 full thrust launch vehicle and consists of a standard Falcon 9 rocket core, with two additional boosters derived from the Falcon 9 first stage.
