NASA will conduct an uncrewed demonstration of its Artemis III lunar landing architecture in 2027, one year before astronauts touch down on the Moon's surface. The test mission will validate critical rendezvous and docking procedures between commercial human landing systems and the Orion spacecraft in lunar orbit.
This demonstration serves as a dress rehearsal for operations teams on Earth and aboard Orion. Controllers will practice the complex sequence of maneuvers required to safely guide the spacecraft to the Moon, separate the lander from Orion, and execute the descent to the surface. The data gathered will inform final procedures before the crewed landing in 2028.
NASA selected multiple commercial partners to develop human landing systems for Artemis, including SpaceX with its Starship HLS variant and Blue Origin with the Blue Moon lander. The 2027 uncrewed test will validate whichever system flies the demonstration mission, confirming that the spacecraft can reliably dock with Orion and execute the landing sequence without crew aboard.
This staged approach reflects lessons learned from Apollo and decades of spaceflight operations. Uncrewed demonstrations reduce risk before committing astronauts to the mission profile. The test also allows NASA and its commercial partners to identify potential issues with hardware, software, and procedures in a lower-stakes environment.
The 2027 mission directly supports NASA's broader Artemis program timeline. The agency aims to return humans to the lunar surface for the first time since 1972, establishing a sustained presence that will support future missions to Mars. Astronauts will conduct scientific research at the Moon's south polar region, an area rich in water ice and permanently shadowed craters.
Uncrewed demonstration missions in lunar orbit will follow the 2027 test, providing additional validation data for NASA and its commercial partners. This iterative approach ensures that by 2028,
