NASA Details Preliminary Artemis III Plans for Return to the Moon
NASA has outlined preliminary plans for the Artemis III mission, a crewed Earth-orbit test flight in late 2027 to evaluate Orion spacecraft rendezvous and docking with commercial landers from Blue Origin and SpaceX ahead of the Moon landing in Artemis IV. The mission will use a mass simulator spacer instead of an upper stage, test upgraded systems like the heat shield, and involve astronauts interacting with lander test articles for the first time.
NASA has detailed plans for Artemis III, a critical Earth-orbit mission scheduled for no earlier than late 2027. The mission will launch the Orion spacecraft aboard the Space Launch System (SLS) rocket from Kennedy Space Center in Florida, carrying four crew members. Unlike previous flights, Artemis III will use a mass simulator spacer—representing the size and weight of an upper stage—between Orion and the launch vehicle, with fabrication underway at Marshall Space Flight Center in Alabama. The primary goal is to test rendezvous and docking capabilities between Orion and commercial landers from Blue Origin and SpaceX, reducing risks before astronauts land on the Moon’s South Pole in Artemis IV. NASA will also evaluate life support systems, docking performance, and an upgraded heat shield for future missions. Astronauts may enter at least one lander test article, refining operations for upcoming lunar surface missions. Orion’s European-built service module will adjust its orbit around Earth, allowing coordinated launches for Orion, Starship (SpaceX’s human landing system), and Blue Moon Mark 2 (Blue Origin’s lander). The mission will inform lander habitation concepts and mission operations, with NASA continuing to refine plans, including astronaut training and spacesuit interfaces with Axiom’s AxEMU suits. This mission marks NASA’s most complex to date, integrating multiple spacecraft and partners to test integrated operations before lunar landings. Engineers are assessing mission profiles and operational considerations to ensure success, with decisions on crew entry into landers and other details still under review.
