NASA replaces Artemis 1's leaky fuel seals
 

NASA has completed a critical repair of its next-generation Space Launch System (SLS) rocket. On Friday, engineers replaced the leaky seal that forced the agency to scrub its most recent attempt to launch Artemis 1. On September 3rd, a fitting on one of the fuel lines to the SLS began leaking hydrogen. Ground crew at Kennedy Space Center tried to troubleshoot the problem three times, only for the leak to persist and force NASA to call off the launch attempt. On Friday, engineers also replaced the seal on a 4-inch hydrogen “bleed line” that was responsible for a smaller leak during an earlier August 29th launch attempt.
