Artemis II Delayed Again by Liquid Hydrogen Leak During WDR

During a pre-launch wet dress rehearsal tanking test, a liquid hydrogen fuel leak was discovered at the base of SLS. Additional issues included a faulty valve on Orion, audio communication problems, and cold-weather camera failures. Launch was pushed from late February to March or later, adding to the growing list of Artemis II delays. SLS Program Manager John Honeycutt noted the 3+ year gap between launches increased the risk of encountering issues.
