Weather permitting, NASA plans to move the Space Launch System rocket and Orion spacecraft for Artemis II off Launch Pad 39B at the agency Kennedy Space Center in Florida as soon as Tuesday, Feb 24. The integrated stack will travel back to the Vehicle Assembly Building so teams can investigate and correct an issue with helium flow to the rocket upper stage.

NASA chief Jared Isaacman on Saturday ruled out a March launch for Artemis 2, the first crewed flyby mission to the Moon in more than 50 years, citing technical issues.
Workers detected a problem with helium flow to the massive SLS rocket that will "take the March launch window out of consideration," Issacman said in a post on X.
"I understand people are disappointed by this development.
