for the first Artemis lunar landing:
Artemis III: NASA added a new demonstration mission in low Earth orbit in mid-2027 to test one or both commercial landers from SpaceX and Blue Origin respectively. The mission will launch crew in Orion on top of the SLS rocket to test rendezvous and docking capabilities between Orion and private commercial spacecraft needed to land astronauts on the Moon. This test will take place with one or both providers.
Artemis IV: NASA continues to target the first Artemis lunar landing in early 2028, which has been the target landing date since mid-2025. After launch, crew will transfer from Orion to a commercial lunar lander for transportation to the surface of the Moon. Lander readiness will determine which provider will safely carry them to the surface and back to Orion in lunar orbit before crew return home aboard Orion – splashing down safely in the Pacific Ocean. Work to standardize the SLS rocket will be implemented for Artemis IV. With this architecture approach, NASA is assessing alternative options for the second stage of the rocket. The interim cryogenic propulsion stage used for the first three missions will be replaced with a new second stage, and the agency is no longer planning to use the Exploration Upper Stage or Mobile Launcher 2, as development of both has faced delays.
Artemis V: Using the standardized configuration of the SLS rocket, NASA anticipates launching this lunar surface mission by late 2028, and future missions about once per year thereafter. This mission also is when NASA is expected to begin building its Moon base.
