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 50 years, demonstrating renewed international commitment to deep space exploration. It directly affects NASA's Artemis program timeline, international space partnerships, and scientific research capabilities. The success of Artemis II is crucial for validating spacecraft systems before attempting lunar landings, impacting future Mars mission planning and inspiring a new generation of STEM professionals.
Context & Background
- The last human lunar fly-by was Apollo 17 in 1972, ending NASA's Apollo program
- Artemis I completed an uncrewed test flight around the Moon in 2022
- The Artemis program aims to establish sustainable lunar presence by the late 2020s
- International partnerships include ESA, CSA, and JAXA contributing to Gateway lunar station
- Artemis II will use NASA's Orion spacecraft and Space Launch System (SLS) rocket
What Happens Next
Following Artemis II's planned 2025 launch, Artemis III will attempt the first crewed lunar landing since Apollo, currently scheduled for 2026. NASA will begin Gateway lunar station assembly in 2025-2026, with international modules arriving through 2028. Commercial lunar lander development continues for future Artemis missions, with SpaceX's Starship selected for Artemis III landing system.
Frequently Asked Questions
Artemis II uses modern technology including advanced computers, life support systems, and international spacecraft components. Unlike Apollo missions that went directly to lunar orbit, Artemis II will test systems for future Gateway station operations and demonstrate new navigation capabilities for deep space travel.
Scientific goals include studying lunar water ice for potential resources and conducting astronomy from the Moon's far side. Strategic objectives involve testing technologies for Mars missions and establishing sustainable presence as a stepping stone for deeper space exploration beyond Earth's immediate neighborhood.
The four-person crew includes NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen. This represents the most diverse lunar mission crew in history, including the first woman, first person of color, and first non-American to travel to lunar distance.
Primary risks include radiation exposure beyond Earth's magnetic field and testing new life support systems in deep space for the first time. The mission will also validate Orion's heat shield performance during high-speed Earth reentry, which is faster than typical ISS return trajectories.
The mission is planned for approximately 10 days, including transit to lunar distance, multiple orbits around Earth with increasing altitude, and a lunar fly-by before returning. This is shorter than Apollo missions but focuses on testing critical systems for longer future missions.
