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 news matters because Artemis II represents humanity's first crewed mission to lunar space since Apollo 17 in 1972, marking a critical step toward establishing sustainable lunar exploration. The mission directly affects NASA's international partners, commercial space companies, and scientific communities who depend on lunar research. It also impacts public interest in space exploration and inspires STEM education globally. The success of Artemis II will validate spacecraft systems for future lunar landings and Mars missions.
Context & Background
- Artemis II follows the uncrewed Artemis I mission that successfully tested the Space Launch System rocket and Orion spacecraft in 2022
- NASA's Artemis program aims to land the first woman and first person of color on the Moon by 2025 with Artemis III
- The last human mission to lunar space was Apollo 17 in December 1972, ending NASA's Apollo program after six successful Moon landings
- Artemis II will be the first crewed test of NASA's Orion spacecraft and Space Launch System rocket combination
- The mission involves international collaboration with the European Space Agency providing Orion's service module
- Artemis program represents a shift toward sustainable lunar exploration with commercial and international partnerships
What Happens Next
Following Artemis II's planned 2024 launch, NASA will proceed with Artemis III for the first crewed lunar landing since 1972, currently scheduled for 2025. The Gateway lunar space station construction will accelerate, with first modules launching in late 2024. Commercial lunar lander development by companies like SpaceX and Blue Origin will progress for future surface missions. International partner contributions will expand, with Japan and Canada providing Gateway components and rover systems.
Frequently Asked Questions
Artemis II will travel approximately 6,400 miles beyond the Moon's far side, following a 'hybrid free return trajectory' that takes the crew farther from Earth than any humans have traveled before. This exceeds Apollo missions' distances and tests navigation and communication systems in deep space. The trajectory ensures a safe return to Earth without requiring major engine burns near the Moon.
The four-person crew includes NASA astronauts Reid Wiseman (commander), Victor Glover (pilot), Christina Koch (mission specialist), and Canadian Space Agency astronaut Jeremy Hansen (mission specialist). This represents NASA's most diverse lunar crew to date, with Koch becoming the first woman to travel to lunar space and Hansen the first non-American to fly to the Moon.
Artemis II primarily serves as a crewed test flight to validate Orion spacecraft systems, life support, and communication capabilities in deep space environment. The mission will test the spacecraft's performance with astronauts aboard during critical maneuvers including trans-lunar injection and high-speed Earth reentry. Success will certify Orion and SLS for crewed lunar landing missions.
The mission is planned to last approximately 10 days, with specific timeline depending on launch window and orbital mechanics. The crew will spend several days traveling to the Moon, perform a lunar flyby, then return to Earth. This duration tests life support systems and crew endurance for future longer missions to lunar Gateway and surface operations.
No, Artemis II will not enter lunar orbit but will perform a 'free return trajectory' that uses the Moon's gravity to slingshot the spacecraft back to Earth. The crew will travel around the Moon's far side at closest approach of about 6,400 miles, providing spectacular views while testing communication blackout periods. This trajectory minimizes fuel requirements while testing critical systems.
