NASA Plans Artemis III Lander Docking Demonstration in Earth Orbit

NASA plans to use Artemis III for a low Earth orbit demonstration in which test versions of Blue Origin’s and SpaceX’s lunar landers rendezvous and dock with Orion. The agency targets the demonstration for next year and aims to return astronauts to the lunar surface in 2028; that date remains a target, not a guarantee.

NASA’s initial crewed lunar landing plans call for two astronauts to descend to the surface while two remain aboard Orion.

Key details

NASA says both providers will take part in the Artemis III demonstration, and it has not assigned either company to a specific lunar landing mission under the revised plan. The agency will make those assignments based on readiness. Before the relevant crewed missions, each provider must demonstrate its lander without a crew, and NASA will certify each system before crewed flight. SpaceX’s plan calls for multiple Starship launches to transfer cryogenic propellant to an orbital depot. The lander would refuel there, then meet Orion in Earth orbit before the spacecraft head toward the Moon. Blue Origin’s accelerated Blue Moon Mark 2 plan calls for the lander and three transfer stages to assemble in Earth orbit, travel to an elliptical polar orbit around the Moon, and shed stages as they use their propellant. NASA’s initial crewed landing profiles place two astronauts in the lander while two remain with Orion. The agency’s plans also call for two lunar surface excursions of about two hours each. NASA says SpaceX will add two Starship crew-cabin demonstrations, while Blue Origin will add human-in-the-loop testing and readiness milestones.

Why it matters

The revised plan makes orbital rendezvous and docking a central step in preparing the landers for lunar missions. For US aviation and aerospace audiences, the program also illustrates how crewed spaceflight depends on coordinated launches, orbital refueling, docking, and staged vehicle operations. NASA says the added contract milestones will support oversight of development and mission preparation.

What happens next

NASA targets the Artemis III in-orbit demonstration for next year and a crewed lunar landing in 2028. The agency has not yet assigned Blue Origin or SpaceX to a specific landing mission; it says readiness will guide those decisions. Both providers must complete uncrewed lander demonstrations, and NASA must certify their systems before crewed flight.
