NASA defended preparations for Artemis 2 after a fueling test had hydrogen leaks like those that bedeviled Artemis 1 more than three years ago.

NASA completed the Artemis II wet dress rehearsal and is reviewing test data after fueling challenges, with March identified as the earliest possible launch opportunity.

NASA had previously pointed at February 6 as the earliest possible date for the Artemis 2 mission to be launched.
