Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.
Here are the basics for the first five missions under the Artemis program:
Artemis I: NASA successfully completed an uncrewed test flight of SLS rocket and Orion spacecraft in November 2022. This mission tested launching the rocket for the first time using new exploration ground systems and evaluated Orion systems not including astronauts or critical life support systems planned on the next mission.
Artemis II: The test flight will be the first flight with crew aboard the SLS rocket and Orion spacecraft. Following a successful wet dress rehearsal in February, NASA discovered a helium flow issue to the interim cryogenic propulsion stage and rolled the rocket and spacecraft back to the Vehicle Assembly Building for repairs. Engineers at NASA’s Kennedy Space Center in Florida are currently working on the stacked SLS rocket and Orion spacecraft to address the issue that required rollback, and teams also are taking the time to swap batteries and more. The next launch window opens in April. Crew members include NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen to venture on an approximately 10-day mission that will send crew around the Moon and back.
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.
Artemis I was the first integrated flight test of NASA’s Deep Space Exploration Systems: the Orion spacecraft, Space Launch System (SLS) rocket, with the upgraded Exploration Ground Systems at Kennedy Space Center in Cape Canaveral, Florida.
Total distance traveled: 1.4 million miles
Re-entry speed: 24,581 mph (Mach 32)
NASA’s Orion spacecraft is carrying humanity to the Moon. Launching atop NASA’s SLS (Space Launch System) rocket, Orion will carry and sustain the crew on Artemis missions to the Moon and return them safely to Earth.
