NASA's Artemis II fueling fix stalls in latest test
NASA's latest confidence test of the Space Launch System fueling system, including newly replaced seals, partially filled the core-stage liquid hydrogen tank and then encountered a ground support equipment issue that reduced hydrogen flow. The test followed a hydrogen leak observed during Artemis II prep; engineers will purge the line and inspect equipment, including replacing a suspected filter. Artemis II's March launch window could be at risk, but NASA says safety remains the priority and work will continue.
