NASA has detailed its overhauled mission architecture for Artemis 3, transforming what was originally planned as a crewed lunar landing into a complex orbital testing campaign. Under the updated framework, the agency will launch three spacecraft across three separate heavy-lift rockets from Florida within a two-week window.

The mission will begin with Blue Origin launching its New Glenn rocket, placing a test variant of the Blue Moon Mark 2 lander into low Earth orbit at an altitude of approximately 440 kilometres (273 miles).
Following the initial launch, NASA will fire its Space Launch System (SLS) carrying the Orion crew capsule into a 555-kilometer (345-mile) orbit. The four-person crew, comprising NASA astronauts Randy Bresnik, Frank Rubio, and Andre Douglas alongside European Space Agency astronaut Luca Parmitano, will dock Orion with the Blue Moon Mark 2. Over two days, the crew will enter the lander to test its environmental controls, life-support systems, and flight software.
After undocking, Orion will perform a second rendezvous with SpaceX’s Starship (Version 3), launched on a separate heavy-lift mission:
- Short-Duration Evaluation: The Starship docking test will span just two hours, evaluating mechanical interface and communication stability without crew entry.
- Commercial Integration: The dual approach validates how Orion interfaces with two distinct commercial landing architectures during a single orbital mission.
- Suit Testing: Astronauts will also evaluate the next-generation Orion Crew Survival System suits designed for deep-space operations.
Following the orbital tests, the crew will spend five additional days conducting system checks before returning to Earth.
While NASA targets a potential summer 2027 launch window to clear the path for a crewed lunar landing on Artemis 4 in 2028, internal communications indicate the mission is currently running three months behind schedule.
