Artemis II Moon Mission Delayed by Helium Fix Rollback and Repairs
NASA's Space Launch System rocket for the Artemis II crewed Moon mission is back in the hangar for repairs after a helium-system issue, following hydrogen-leak fixes; engineers will diagnose the problem at Kennedy Space Center, with an April launch still possible though timing remains tight. The four-person crew—three Americans and one Canadian—remains on standby as NASA works to resolve the issues before the first crewed lunar flight since Apollo.
