Before Artemis astronauts land on the Moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the Moon, will support astronaut safety and mission success for crewed lunar landings.

NASA is working with two American companies to develop the human landing systems that will safely transport astronauts from lunar orbit to the Moon’s surface and back for future Artemis missions. For Artemis III, both SpaceX and Blue Origin will fly test versions, or test articles, of the crewed landers that will be used for future Moon landings. The lander test articles will launch by commercial rockets, while the Artemis III crew will launch to low Earth orbit in Orion atop the agency’s SLS (Space Launch System) rocket.

NASA and the human landing system providers have been working closely together to plan and determine capabilities for the Artemis III mission. With missions fast approaching, both SpaceX and Blue Origin are optimizing hardware availability and capability. SpaceX plans to use the company’s latest version of Starship and basis of the future Starship HLS, called Version 3, while Blue Origin will test their planned HLS crew cabin, allowing each company to apply lessons learned prior to uncrewed and crewed missions on the Moon.
