NASA’s Artemis II mission, which had sparked hope for a launch around the Moon next month, has encountered another hurdle. Just a day after officials expressed optimism about its readiness, NASA Administrator Jared Isaacman announced that a new technical issue requires the rocket to be moved back to the Vehicle Assembly Building (VAB) for repairs. The problem arose late Friday when data indicated an interruption in helium flow to the upper stage of the Space Launch System (SLS) rocket, according to Isaacman’s update on X. Engineers are currently investigating the cause, but any potential fixes must be carried out inside the VAB.
