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 a critical step toward returning humans to the Moon for the first time since 1972, advancing NASA's goal of establishing a sustainable lunar presence. It directly impacts the global space industry, international space agencies collaborating with NASA, and scientific communities planning lunar research. The success of Artemis II builds confidence for the subsequent Artemis III mission that aims to land astronauts on the lunar surface, potentially including the first woman and person of color to walk on the Moon.
Context & Background
- Artemis II is the first crewed mission in NASA's Artemis program, following the uncrewed Artemis I test flight that orbited the Moon in late 2022.
- The Apollo program's last human lunar landing was Apollo 17 in December 1972, marking over 50 years since humans last visited the Moon.
- Artemis II will carry four astronauts—three NASA astronauts and one Canadian Space Agency astronaut—on a lunar flyby mission without landing.
- The mission tests the Orion spacecraft's life support systems and radiation protection for deep space travel, crucial for future Mars missions.
- NASA's Artemis program involves international partners including ESA (European Space Agency), JAXA (Japan), and CSA (Canada), plus commercial partners like SpaceX developing the Human Landing System.
What Happens Next
Following the 10-day mission completion, NASA will analyze flight data to certify systems for Artemis III, currently scheduled for no earlier than September 2026. The agency will also begin final preparations for the SpaceX Starship Human Landing System demonstration mission. International partner contributions, including ESA's European Service Module and Gateway lunar station components, will progress toward integration for future Artemis missions.
Frequently Asked Questions
Artemis II primarily tests the Orion spacecraft's systems with astronauts aboard during a lunar flyby, validating life support, communication, and radiation protection for future deep space missions. It serves as the final crewed test before Artemis III attempts a lunar landing.
Artemis II uses modern technology, international collaboration, and commercial partnerships unlike the purely government-run Apollo program. While Apollo missions focused on short lunar visits, Artemis aims for sustainable lunar exploration as a stepping stone to Mars.
The crew includes NASA astronauts Reid Wiseman (commander), Victor Glover (pilot), and Christina Koch (mission specialist), plus Canadian Space Agency astronaut Jeremy Hansen (mission specialist). This represents the most diverse lunar mission crew in history.
NASA aims to establish a sustainable lunar presence to test technologies for Mars missions, conduct scientific research on lunar resources like water ice, and maintain U.S. leadership in space exploration amid growing international competition from China and other nations.
Primary risks include radiation exposure beyond Earth's magnetic field, spacecraft system failures in deep space, and re-entry challenges at higher speeds than low-Earth orbit missions. The mission tests new safety protocols for these unprecedented conditions.
