NASA is pushing the proposed launch date for its Artemis II lunar mission back to at least March after finding a hydrogen leak during a major fueling test.

The agency is delaying the liftoff to allow teams to review data and conduct a second test, which it calls a wet dress rehearsal. The crew — NASA’s Reid Wiseman, Victor Glover and Christina Koch, and the Canadian Space Agency’s Jeremy Hansen — will be released from quarantine, which they entered in Houston on Jan. 21.
