Second SLS WDR appears to go as planned – March 6 target
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…

Umbilical hardware arrives for SLS ML-2, runs out of funding
The construction of NASA’s second Space Launch System Mobile Launcher (ML-2) has been delayed after NASA ran out of near-term funding. ML-2 is required due to the increase in height for the Block 1B version of the rocket, making it incompatible with the billion-dollar ML-1. However, some planned work will continue, such as testing umbilicals…
