NASA is now targeting a launch in March 2026 for its Artemis II mission, the first crewed flight around the moon in more than 50 years, after a critical fueling test at the agency's Kennedy Space Center in Florida revealed challenges delaying liftoff beyond the previously planned February launch window.

NASA has delayed the planned launch of moon rocket with a Canadian on board until at least March.

During a routine dress rehearsal of the launch, persistent liquid hydrogen leaks were discovered in the Artemis II rocket.
