Artemis II inches back to the pad for a careful rollout after helium fix

NASA is rolling the 322-foot Space Launch System rocket and its Orion crew capsule back to Kennedy Space Center's launch pad for Artemis II, a 10-day crewed lunar mission that could launch as early as April 1. The 4-mile crawl, using a crawler-transporter at about 1 mph, follows a prior rollback to repair a helium-flow blockage uncovered during a wet dress rehearsal. Engineers replaced a seal and batteries and conducted tests. The crew includes Reid Wiseman, Christina Koch, Victor Glover, and Jeremy Hansen, who would travel farther from Earth than any humans to date.
