NASA delays Artemis missions again. What could this mean for the moon, Mars and space leadership?

A portion of the far side of the Moon looms large just beyond the Orion spacecraft in this image taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays. .

NASA's first two crewed Artemis moon missions have been pushed back to 2026 and 2027, respectively, and the move could have big ramifications for the agency's Artemis program and competition with China for leadership in space.

Artemis 2, which will send a crew of three Americans and a Canadian astronaut around the moon, was due to launch in September 2025. The mission has now been moved back to April 2026, NASA announced on Dec. 5. Artemis 3 — which is set to put humans on the surface of our nearest celestial neighbor for the first time in more than half a century — has also slipped, from late 2026 to mid-2027.
