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
The Artemis II mission represents humanity's first crewed lunar mission since 1972, marking a critical step toward establishing sustainable human presence on the Moon. This mission directly impacts international space collaboration, scientific research capabilities, and technological development that will benefit multiple industries on Earth. It matters to space agencies worldwide, aerospace contractors, scientific communities, and anyone interested in human exploration beyond low-Earth orbit. The success of Artemis II will determine the timeline for future lunar landings and eventual Mars missions.
Context & Background
- NASA's Artemis program aims to return humans to the Moon by 2025 with Artemis III, following the uncrewed Artemis I test flight in 2022
- The last human mission to the Moon was Apollo 17 in December 1972, ending the Apollo program after six successful landings
- Artemis II will be the first crewed test of NASA's Space Launch System (SLS) rocket and Orion spacecraft, building on lessons from Artemis I
- International partners including ESA (European Space Agency), CSA (Canadian Space Agency), and JAXA (Japan Aerospace Exploration Agency) are contributing to Artemis program elements
- The mission is part of NASA's Moon to Mars exploration approach, using the Moon as a proving ground for deep space technologies
What Happens Next
Following Artemis II's lunar flyby (expected in late 2025 or 2026), NASA will analyze mission data for approximately 6-12 months before proceeding with Artemis III lunar landing preparations. Key upcoming milestones include final crew selection announcements, completion of Orion spacecraft modifications based on Artemis I findings, and SLS rocket assembly at Kennedy Space Center. International partner contributions like ESA's European Service Module and CSA's robotic arm will undergo final integration testing throughout 2024-2025.
Frequently Asked Questions
Artemis II is planned as a 10-day mission that will include a lunar flyby but not a landing. The crew will travel approximately 6,400 miles beyond the far side of the Moon before returning to Earth, testing systems for future longer-duration missions.
NASA has announced four astronauts: commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and mission specialist Jeremy Hansen (from CSA). This represents the most diverse lunar crew in history, including the first woman and first person of color on a lunar mission.
Artemis II is a crewed test flight that will orbit the Moon without landing, while Artemis III will land astronauts near the lunar South Pole. Artemis II validates life support and spacecraft systems, while Artemis III will test new technologies including next-generation spacesuits and lunar landers.
NASA aims to establish sustainable lunar exploration as a stepping stone to Mars, leveraging new technologies and international partnerships. Scientific goals include studying lunar water ice, conducting astrophysics research, and testing technologies for future deep space missions that weren't available during Apollo.
Primary risks include first-time crewed operation of SLS and Orion systems, radiation exposure beyond Earth's magnetic field, and re-entry at higher speeds than typical ISS missions. NASA is addressing these through extensive testing, improved radiation protection, and enhanced heat shield designs based on Artemis I data.
