”Accessing and remediating any of these issues can only be performed in the VAB.”
A day after NASA officials expressed optimism that they could be ready to launch the Artemis II mission around the Moon next month, the space agency’s administrator announced Saturday that a new problem will require the removal of the rocket from its launch pad in Florida.
The latest issue appeared Friday evening, when data showed an interruption in helium flow into the upper stage of the Space Launch System rocket, NASA Administrator Jared Isaacman wrote in a post on X. Isaacman posted a more thorough update Saturday, writing that engineers are still examining the potential cause of the problem, but any fixes must take place inside the Vehicle Assembly Building.
That means NASA and contractor ground teams will immediately begin preparing to roll the 322-foot-tall (98-meter) SLS rocket off of Launch Complex 39B and back to the VAB. The rocket and its mobile launch platform will ride NASA’s crawler-transporter for the 4-mile journey.
