Before astronauts return to the lunar surface, NASA will first conduct one of the most ambitious and complex test missions in the agency’s history.
Launching in 2027, Artemis III will send NASA astronauts Randy Bresnik, Frank Rubio, Andre Douglas, and ESA (European Space Agency) astronaut Luca Parmitano aboard the Orion spacecraft into low Earth orbit to perform a series of demonstrations with test versions, or test articles, of human landing systems being developed by industry partners Blue Origin and SpaceX. During the planned 14-day mission, crews and flight controllers will practice the rendezvous, docking, habitation, and operational procedures that will be essential when Artemis astronauts begin landing near the Moon’s South Pole in 2028. The mission is designed to reduce risk, validate hardware, and gain operational experience before NASA attempts a crewed lunar landing.
“Every piece of this mission in Earth orbit is designed to reduce risk before we put astronauts back on the Moon,” said Jeremy Parsons, NASA’s Artemis program manager. “We’re launching three spacecraft on three different rockets and testing how they operate together — something NASA has never attempted. Every lesson we learn here gets us closer to landing on the Moon in 2028.”
First stop: Blue Origin’s lunar lander test article
Earlier Artemis missions used only NASA’s SLS (Space Launch System) rocket and Orion spacecraft. Artemis III will involve three separate spacecraft launched on three different heavy-lift rockets within a relatively short period of time.
The mission begins with Blue Origin launching a test version of its Blue Moon Mark 2 lander into a circular low Earth orbit approximately 273 miles (237 nautical miles) above Earth. The spacecraft can remain on orbit for up to 30 days providing schedule flexibility. Artemis III is designed as a tightly choreographed campaign, with NASA planning to launch Orion on top of SLS from the agency’s Kennedy Space Center in Florida only days after the Blue Moon test article launch and confirmation the vehicle is healthy and ready for joint operations.
Following launch, Orion will initially enter an elliptical Earth orbit of 18 x 1122 miles (16 x 975 nautical miles). It will use its service module to perform a series of maneuvers to transition to a circular orbit at about 345 miles (300 nautical miles) for thermal stabilization before then gradually setting up its rendezvous with the waiting Blue Moon lander test article. Because each spacecraft operates in slightly different orbital regimes optimized for its mission requirements, Artemis III requires a carefully choreographed sequence of orbital maneuvers and rendezvous operations throughout the flight.
During the first two days of flight, the crew will check out Orion’s systems, prepare for proximity operations, and gradually position themselves for the mission’s first major objective: rendezvous and docking with the Blue Moon test vehicle.
