Artemis II hydrogen headaches highlight legacy hardware challenges
TL;DR
NASA is still troubleshooting persistent liquid hydrogen leaks on the Artemis II rocket during a wet dress rehearsal, delaying tests and echoing past issues from Artemis I and the Space Shuttle era. The problem stems from hydrogen’s properties and the SLS’s legacy design, a product of congressional decisions to reuse Shuttle hardware. Engineers are replacing seals and refining fueling procedures, but officials say Artemis II is an experimental vehicle, and a permanent fix would require a major redesign rather than a quick workaround.
