Artemis 1 was NASA’s first uncrewed test flight of the Orion spacecraft and Space Launch System rocket. It launched on November 16, 2022, orbited the Moon, and ended with a successful splashdown in the Pacific Ocean on December 11, 2022.

What happened

The mission was designed to test the rocket, spacecraft, deep-space systems, and reentry performance before crewed flights. NASA reports that Artemis I lasted 25 days, 10 hours, and 53 minutes, traveled about 1.4 million miles, and returned safely to Earth.

Why it mattered

Artemis 1 was the first mission in NASA’s Artemis program and served as a proof-of-concept for future Moon missions. It showed that Orion could survive a lunar mission and high-speed reentry, which helped clear the way for later Artemis flights.

In plain terms

Nothing “went wrong” in the sense of a mission failure; the spacecraft completed its test objectives and came home successfully. Before launch, the mission did face delays from technical issues and weather, but the final flight itself was a success.
