NASA reveals new problem with Artemis II rocket, further delaying launch

"NASA said that engineers had detected an interruption in the flow of helium in the upper stage of the Space Launch System (SLS) rocket. NASA administrator Jared Isaacman confirmed the problem in a social media post and that the rocket will be removed from the launch pad and returned to the Vehicle Assembly Building for repair work. We will begin preparations for rollback, and this will take the March launch window out of consideration, Isaacman wrote."

"Helium flow is required for launch, NASA said in the post, and engineers are deciding what do next. The mission's predecessor, Artemis I, also suffered from a helium problem, although it is unclear if Artemis II's issue is the same, Isaacman said. Artemis II has already been delayed numerous times, most recently due to its failed initial wet dress rehearsal."

Engineers detected an interruption in the flow of helium in the upper stage of the Space Launch System (SLS) rocket for the Artemis II mission. NASA will remove the rocket from the launch pad and return it to the Vehicle Assembly Building for repairs. Administrator Jared Isaacman confirmed the issue and said rollback preparations will remove the March launch window from consideration. Helium flow is required for launch and engineers are determining next steps. The mission has faced multiple delays, including problems during its initial wet dress rehearsal with hydrogen fuel leaks, and the predecessor Artemis I also experienced a helium problem.
