Artemis II delayed to March after hydrogen leak halts fueling test
NASA’s Artemis II crewed lunar mission is pushed to March after a fueling test uncovered recurring hydrogen leaks at the rocket’s ground connections, halting the countdown and prompting a data review and a second Wet Dress Rehearsal. The earliest launch window is March 6, with the four astronauts in quarantine as NASA prioritizes safety before the first crewed lunar flight since 1972.
