NASA worked through a second Wet Dress Rehearsal for Artemis II, after the SLS vehicle experienced hydrogen leaks around propellant loading during the first test.
Work on the Tail Service Mast Umbilical (TSMU) took place while the vehicle remained on Pad 39B, avoiding a rollback and a potential delay to the retargeted launch opportunities in March. That is now a possibility after what appeared to be a smooth and successful second test on Thursday, with NASA now feeling confident about setting March 6 as the target.
