Artemis I spent about 25 days in space. NASA’s mission duration is listed as 25 days, 10 hours, 53 minutes from its Nov. 16, 2022 launch to splashdown on Dec. 11, 2022. Some contemporary summaries also cite roughly 25 days for the round trip, with the Orion capsule returning after a distant retrograde orbit around the Moon.[1][2][3][7]
If you’d like, I can pull the latest official NASA timeline or press materials to confirm any updates or minor variations in mission duration reports.

www.lpi.usra.eduThe roundtrip journey to the moon began Nov. 16 with the blastoff of NASA’s 322-foot-tall (98-meter) Space Launch System moon rocket from Kennedy Space Center in Florida. On Sunday, the Orion crew capsule streaked back into Earth’s atmosphere at more than 24,400 mph (33,370 kilometers per hour), some 32 times the speed of sound, as temperatures on the moonship’s ablative Avcoat heat shield built up to 5,000 degrees Fahrenheit (2,760 degrees Celsius). … The capsule descended just below 200,000...
