The mission is planned to carry out a series of objectives designed to demonstrate critical systems needed for a future lunar landing.
NASA is accelerating preparations for the Artemis III mission, a crewed Earth orbit flight aimed at testing critical rendezvous and docking capabilities between the Orion spacecraft and commercial lunar landers developed by Blue Origin and SpaceX.
Once Orion reaches orbit, its European-built service module will help circularise the spacecraft’s low Earth orbit trajectory.
The mission will also support the evaluation of lander rendezvous procedures, habitation concepts, and operational coordination required for future lunar surface missions.
NASA is further exploring opportunities for international and domestic partners to deploy CubeSats in Earth orbit as part of the mission.

NASA is accelerating preparations for the Artemis III mission, a crewed Earth orbit flight aimed at testing critical rendezvous and docking capabilities between the Orion spacecraft and commercial lunar landers developed by Blue Origin and SpaceX.
The mission was added earlier this year ahead of planned lunar landing missions to the Moon’s south polar region. Since the announcement, NASA engineers have been assessing mission profiles and operational strategies to reduce risks before astronauts return to the lunar surface during Artemis IV.
Jeremy Parsons, Moon to Mars acting assistant deputy administrator, NASA’s Exploration Systems Development Mission Directorate in Washington, said: “While this is a mission to Earth orbit, it is an important stepping stone to successfully landing on the Moon with Artemis IV. Artemis III is one of the most highly complex missions NASA has undertaken. For the first time, NASA will coordinate a launch campaign involving multiple spacecraft, integrating new capabilities into Artemis operations. We’re integrating more partners and interrelated operations into this mission by design, which will help us learn how Orion, the crew, and ground teams all interact together with hardware and teams from both lander providers before we send astronauts to the Moon’s surface and build a Moon Base there.”
The Artemis III mission is designed to validate key systems needed for future Moon landings. NASA’s Space Launch System rocket will launch the Orion spacecraft carrying four astronauts from Kennedy Space Center. Instead of using the interim cryogenic propulsion stage as the rocket’s upper stage, NASA will use a non-propulsive spacer that replicates the upper stage’s size and connection points.
Work on the spacer is already progressing at Marshall Space Flight Center, where engineers are machining materials for the structure ahead of welding and assembly operations.
Once Orion reaches orbit, its European-built service module will help circularise the spacecraft’s low Earth orbit trajectory. NASA said the Earth orbit approach provides greater launch flexibility for Orion, SpaceX’s Starship human landing system pathfinder, and Blue Origin’s Blue Moon Mark 2 lander pathfinder compared to a direct lunar mission.
NASA is also working with both companies to define mission operations, including the possibility that astronauts could board at least one of the lander test vehicles during the mission.
Astronauts aboard Orion are expected to spend more time in space than the crew on Artemis II, enabling NASA to further assess life support systems and conduct the first in-flight demonstration of Orion’s docking system. The mission will also support the evaluation of lander rendezvous procedures, habitation concepts, and operational coordination required for future lunar surface missions.
The agency additionally plans to test an upgraded Orion heat shield during reentry to improve flexibility and performance for future deep-space missions.
In the coming weeks, NASA will continue refining mission details, including astronaut selection timelines, mission duration, potential scientific experiments, and options for evaluating Axiom Space’s AxEMU spacesuit interfaces for future lunar operations. The agency has also requested industry proposals to improve communications during the mission, as the Deep Space Network will not be used.
NASA is further exploring opportunities for international and domestic partners to deploy CubeSats in Earth orbit as part of the mission.
The Artemis programme forms part of NASA’s broader long-term exploration strategy, which aims to establish a sustained human presence on the Moon while laying the groundwork for future crewed missions to Mars.
