Artemis II
Artemis program's second lunar flight
Artemis II is a planned lunar spaceflight mission under the Artemis program, led by NASA. It is intended to be the second flight of the Space Launch System (SLS), and the first crewed mission of the Orion spacecraft. It is the first crewed mission around the Moon, and beyond low Earth orbit, since A...

Why It Matters
This mission represents humanity's return to lunar exploration after more than 50 years, establishing a crucial stepping stone for future Mars missions. It demonstrates international collaboration in space exploration with contributions from NASA, ESA, CSA, and commercial partners. The success of Artemis II directly affects scientific research, technological innovation, and inspires a new generation of space enthusiasts while advancing our understanding of deep space travel.
Context & Background
- The last human moon landing was Apollo 17 in 1972, ending NASA's Apollo program
- Artemis I was an uncrewed test flight that successfully orbited the moon in 2022
- The Artemis program aims to establish sustainable lunar exploration with the Gateway lunar outpost and eventual Mars missions
- Artemis II is the first crewed mission of the program, testing life support systems and Orion spacecraft capabilities
- The mission includes international astronauts representing NASA, CSA (Canada), and potentially other partner agencies
What Happens Next
Following successful launch, Artemis II will conduct a lunar flyby mission lasting approximately 10 days, testing spacecraft systems with crew aboard. If successful, Artemis III will follow with the first crewed lunar landing since 1972, currently scheduled for no earlier than 2025. The mission will pave the way for construction of the Lunar Gateway station and establish protocols for sustained lunar presence.
Frequently Asked Questions
Artemis II uses modern technology including the Space Launch System (SLS) rocket and Orion spacecraft, focuses on sustainable exploration rather than one-time visits, and includes international crew members representing multiple space agencies working toward establishing permanent lunar presence.
The crew includes NASA astronauts as mission commander and pilot, along with mission specialists from NASA and the Canadian Space Agency. This represents the first international crew to travel to lunar vicinity, with specific names to be announced closer to launch.
No, Artemis II is a lunar flyby mission that will orbit the moon but not land. Its primary purpose is to test the Orion spacecraft's systems with crew aboard in deep space environment, paving the way for Artemis III which will include a lunar landing.
The mission is planned to last approximately 10 days, during which the spacecraft will travel to lunar vicinity, complete a lunar flyby, and return to Earth. This duration allows thorough testing of life support systems and spacecraft performance with crew in deep space.
Key objectives include testing Orion's life support systems with crew, validating spacecraft performance in deep space environment, demonstrating re-entry and recovery procedures, and gathering human performance data for future longer-duration missions to the moon and Mars.
