Testing Multiple Spacecraft on Earth Orbit for Artemis III
NASA unveiled a revised flight scenario for the Artemis III mission that relies on three separate rocket launches and two distinct orbital rendezvous maneuvers in low-Earth orbit. The agency shifted the actual lunar landing to the subsequent Artemis IV mission back in February. However, agency officials detailed the mechanics of the upcoming orbital test flight during a press conference at the Kennedy Space Center.
Every phase of this Earth orbit operation is designed to reduce risks before astronauts return to the Moon, Artemis program manager Jeremy Parsons said, according to Novinky. Agency officials acknowledged that NASA has never previously executed an orbital operation involving three separate spacecraft launched on three different rockets.
How Orion, Blue Moon, and Starship Will Connect in Orbit
The sequence begins when Blue Origin launches a test version of its Blue Moon Mark 2 lunar lander into low-Earth orbit. That vehicle will wait at an altitude of approximately 440 kilometers for the arrival of the Orion spacecraft. A Space Launch System rocket will lift the Orion crew into space, carrying NASA astronauts Randy Bresnik, Frank Rubio, and Andre Douglas alongside European Space Agency astronaut Luca Parmitano.
Once Orion docks with the Blue Moon module, the crew will spend about two days inside the lander. They will check life support systems, navigation, communications, and habitat conditions. Orion will then undock and prepare for a rendezvous with SpaceX’s Starship vehicle. That interaction involves testing the docking mechanism and mutual spacecraft coordination over a two-hour window, without crew members entering the Starship cabin.
Contrasting Strategies for SpaceX and Blue Origin
SpaceX altered its mission profile so that Starship docks with Orion in Earth orbit rather than near the Moon. Both joined spacecraft will then fire their engines to travel toward lunar orbit. Two astronauts will transfer to Starship for the descent to the lunar surface, while the other two remain in Orion. This architecture requires Starship to refuel in Earth orbit. SpaceX expects to run its first propellant transfer test between two Starship vehicles in early 2027.
Blue Origin adjusted its approach differently for its first crewed landing. The company plans to execute the mission without requiring propellant transfers in space. Meanwhile, NASA is tightening oversight of both systems. SpaceX must complete two additional tests of its crew cabin, while Blue Origin expands crewed testing of its technologies.
Future Moon Landings and Apollo Precedents
NASA plans the Artemis III test mission for the summer of 2027 without a fixed launch date yet. The agency has not decided whether SpaceX or Blue Origin will handle the first crewed landing in 2028. That choice depends on technical readiness and the results of uncrewed lunar landing tests.
Twelve American astronauts landed on the Moon across six Apollo missions between 1969 and 1972. Neil Armstrong and Buzz Aldrin stepped onto the lunar surface first during Apollo 11 on July 20, 1969. Eugene Cernan and Harrison Schmitt completed the most recent lunar landing during the Apollo 17 mission on December 11, 1972.
