NASA is rolling the Artemis II moon rocket back to the Vehicle Assembly Building at Kennedy Space Center for repairs after a helium flow issue was discovered. Crews will begin the slow move this morning using the crawler transporter, a trip expected to take up to 12 hours to cover about four miles. Once inside the VAB, teams will access the problem area, replace batteries, and retest systems. The delay pushes the next possible Artemis II launch window into April.
