NASA Delays Artemis II Lunar Mission After Helium Flow Failure

NASA's Artemis II lunar mission is facing a significant delay after engineers discovered a critical helium flow interruption in the Space Launch System rocket's upper stage.The technical failure occurred just one day after the agency established a March 6 target for the historic crewed lunar fly-around involving Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen.Because the 322-foot rocket requires repairs that cannot be performed on the launch pad at the Kennedy Space Center, officials are preparing to roll the vehicle back to the Vehicle Assembly Building.This logistical setback cancels all launch windows for March, with NASA now evaluating potential flight dates in April as technicians investigate suspected faulty filters or valves.
