NASA says it needs to haul the Artemis II rocket back to the hangar for repairs

NASA has encountered a new issue with the Artemis II rocket, requiring its removal from the launch pad for repairs. The problem involves an interruption in helium flow into the upper stage of the Space Launch System rocket. Engineers are investigating the cause, but any fixes must be performed inside the Vehicle Assembly Building. This development has ruled out a March launch, with the next launch window starting April 1. The Artemis II mission, which will be the first human spaceflight mission to the vicinity of the Moon since 1972, aims to demonstrate the readiness of the SLS rocket and Orion spacecraft.
