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...
Moon
Natural satellite orbiting Earth
The Moon is the only natural satellite of Earth. It orbits around Earth at an average distance of 384,399 kilometres (238,854 mi), a distance roughly 30 times the width of Earth. It completes an orbit (lunar month) in relation to Earth and the Sun (synodically) every 29.5 days.

Why It Matters
This mission represents the first crewed lunar flight since Apollo 17 in 1972, marking a historic return to human deep space exploration. It directly affects NASA's Artemis program timeline, international space partnerships, and the global aerospace industry. The mission will test critical life support systems and Orion spacecraft performance for future lunar landings, while inspiring a new generation of STEM professionals. Success is crucial for maintaining U.S. leadership in space exploration amid growing international competition from China and other nations.
Context & Background
- The Artemis program was established in 2017 with the goal of returning humans to the Moon and eventually reaching Mars
- Artemis I successfully completed an uncrewed test flight around the Moon in 2022, validating the Space Launch System rocket and Orion spacecraft
- The Apollo program conducted the last crewed lunar missions from 1968-1972, with Apollo 8 being the first to orbit the Moon
- International partnerships include the Artemis Accords signed by over 30 nations establishing principles for peaceful lunar exploration
- The mission will use the most powerful rocket ever built - the Space Launch System - generating 8.8 million pounds of thrust
What Happens Next
Following Artemis II's 10-day mission scheduled for late 2025, NASA plans Artemis III for 2026 which will land astronauts near the lunar south pole. The Gateway lunar space station construction will accelerate in the late 2020s to support sustained lunar presence. Commercial lunar lander development by SpaceX and Blue Origin will progress for future surface missions, with NASA targeting continuous lunar presence by the 2030s.
Frequently Asked Questions
Artemis II will test modern technology including advanced computers, life support systems, and radiation protection not available during Apollo. Unlike Apollo missions that entered lunar orbit, Artemis II will perform a 'free return trajectory' flying around the Moon without entering orbit, testing systems for future landings.
The far side presents communication challenges since it always faces away from Earth, requiring special relay satellites. This region contains the South Pole-Aitken basin, the largest impact crater in the solar system, which scientists want to study for clues about the Moon's formation and potential water ice resources.
Primary risks include radiation exposure beyond Earth's protective magnetosphere, potential spacecraft system failures during critical maneuvers, and emergency scenarios requiring rapid return to Earth. The mission will test new safety protocols and equipment designed to protect astronauts during deep space travel.
Artemis II provides crucial data on human performance and spacecraft systems during extended deep space travel, directly informing Mars mission planning. The radiation protection strategies and life support recycling systems tested will be essential for the 6-9 month journey to Mars planned for the 2030s.
The mission includes Canadian Space Agency astronaut Jeremy Hansen, marking Canada's first lunar mission. European Space Agency provides the Orion service module, and multiple Artemis Accords signatory nations contribute technology and scientific instruments for the broader Artemis program.
