NASA has successfully completed the Artemis II mission, marking the first crewed lunar flyby in over 50 years. The mission lasted 9 days, 1 hour, and 32 minutes, having launched on April 1, 2026. The Artemis II crew consisted of four astronauts: Mission Commander Reid Wiseman, Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen.

Why it matters

The Artemis II mission served as a critical test of deep space systems and human deep space capabilities, establishing the technical foundation for future lunar surface landings and eventual crewed missions to Mars. By successfully navigating a lunar flyby and executing a precise splashdown, NASA has verified the viability of the Orion and SLS architecture for long-term lunar exploration.

The details

The mission utilized two primary pieces of hardware: the Orion spacecraft and the Space Launch System (SLS) rocket. The Orion spacecraft is designed as an exploration vehicle capable of sustaining a crew during missions to the Moon and ensuring their safe return to Earth. It was launched via the SLS, NASA's new heavy-lift rocket engineered to provide more payload mass, volume, and departure energy than any other single rocket.

  • The Artemis II mission launched on April 1, 2026.
  • The crew completed a second return correction burn on Flight Day 9.
  • The crew performed a final burn before the capsule began its re-entry sequence on Flight Day 10.
  • The Orion spacecraft splashed down in the Pacific Ocean off the coast of San Diego on April 10, 2026.

What they’re saying

“Y'all, we did it. We sent four amazing people to the moon and safely returned them to Earth for the first time in more than 50 years.”

— Lori Glaze, Acting associate administrator of NASA's Exploration Systems Development Mission Directorate

What’s next

The completion of Artemis II paves the way for subsequent missions aimed at landing astronauts on the lunar surface, furthering the objective of establishing a sustainable human presence on the Moon as a stepping stone for Mars exploration.

The takeaway

This mission marks a transition from uncrewed testing to crewed operations in deep space. By successfully navigating a lunar flyby and executing a precise splashdown, NASA has verified the viability of the Orion and SLS architecture for long-term lunar exploration, a critical step towards future Moon landings and Mars missions.
