NASA says it can't try until March at the earliest to send a crewed spacecraft on a flight around the moon and back, due to hydrogen leaks during testing of the Artemis II rocket.

NASA terminated Artemis-II's crucial wet dress rehearsal due to hydrogen leak in its SLS rocket.

The leaks — reminiscent of the rocket’s delayed debut three years ago — sprang just a couple hours into the daylong fueling operation at Kennedy Space Center.
