Artemis I - NASA
Artemis I was the first in a series of increasingly complex missions that will enable human exploration at the Moon and future missions to Mars.
www.nasa.govAnswer: Artemis I spent about 25 days, 10 hours, and 53 minutes in space.
Details:
- Core mission duration: 25 days, 10 hours, 53 minutes from launch on November 16, 2022 to splashdown on December 11, 2022. This duration is repeatedly cited by NASA as the primary metric for Artemis I [NASA Artemis I mission page: duration 25 days, 10 hours, 53 minutes] [NASA mission timeline: duration 25 days, 10 hours, 53 minutes].
- Path and distance: The mission traveled roughly 1.4 million miles (about 2.1 million kilometers) including a distant retrograde orbit around the Moon before return to Earth [NASA Artemis-I press/overview material] [LPI Artemis press kit shows 42 days total mission duration for the broader public-facing document, but the mission’s primary flight test duration is the 25 days, 10 hours, 53 minutes figure used by NASA’s official mission pages].
- Note: Some public materials (e.g., older press kits) reference longer accounting that includes early readiness windows or assumed extended timelines; however, NASA’s official mission fact sheets and timelines consistently list the Orion-ESA-SLS Artemis I flight test duration as 25 days, 10 hours, 53 minutes in space [NASA Artemis I mission facts, NASA reference page].
If you’d like, I can pull exact citations and show the primary NASA pages and a side-by-side with the press kit figures.
