Artemis II Moon Mission Delayed by Helium Issue
NASA delays Artemis II after a helium-flow problem forces engineers to roll back the SLS rocket, delaying the first crewed lunar flyby and prompting an investigation.
NASA chief Jared Isaacman announced that Artemis II, the first crewed Moon flyby in more than five decades, will not launch in March because a helium flow issue was detected in the upper stage of the SLS rocket. "take the March launch window out of consideration," he wrote on X, noting the disappointment felt by the team but praising their tireless work.
The towering SLS rocket and Orion spacecraft will be rolled back into the Vehicle Assembly Building at the Kennedy Space Center in Cape Canaveral, Florida, to investigate the technical problems and carry out any necessary repairs. A complete briefing is planned in the coming days.
Artemis II is slated to last about 10 days and would carry three Americans and one Canadian on a mission to loop around Earth’s Moon, a major step toward returning humans to the lunar surface. On Friday, March 6 had been identified as the earliest possible launch date, amid global interest as China advances its own lunar plans toward 2030 for a crewed mission. The pace of developments underscores NASA’s effort to balance ambition with safety as the Artemis program moves forward.
NASA has emphasized that this is a delay to ensure reliability and safety, and officials will communicate any new timeline once repairs are complete and tests are satisfactory.
