NASA to Roll Back Artemis II SLS Rocket from Launch Pad after Discovering Interruption in Helium Flow

NASA will no longer launch the Artemis II mission during the March launch window after deciding to roll back the SLS rocket and Orion spacecraft to the Vehicle Assembly Building (VAB). NASA observed an interruption in the flow of helium to the rocket’s interim cryogenic propulsion stage on Friday 21 February, forcing the roll back.
