NASA restarted the countdown for Artemis II after fixing liquid hydrogen leaks by replacing seals and a clogged filter at Kennedy Space Center. The two-day wet dress rehearsal will culminate in a fuel-fill test, with the four Artemis II astronauts monitoring remotely, and, if all tests are leak-free, could lead to a March launch window for the crewed Moon mission.
NASA continues to wrestle hydrogen leaks on the Space Launch System as Artemis 2 pursues a March liftoff; after Artemis 1 delays, technicians replaced two seals in the tail service mast umbilicals and rechecked interfaces, with Artemis 2’s wet dress rehearsal going more smoothly. Hydrogen’s tiny molecules and ultra-cold temperatures make seals brittle and leaks hard to eradicate, but lessons from Artemis 1 have improved procedures and testing—only further checks will confirm a reliable Artemis 2 launch.
