NOT AGAIN: NASA Artemis rocket springs another fuel leak ahead of launch
Launch controllers are continuing the flow of liquid nitrogen tocore stage after another liquid hydrogen fuel leak was detected and reoccurred twice Saturday morning ahead of the second launch attempt.
The leak was located in the cavity between the ground and flight side plates of the quick disconnect and teams warmed up the quick disconnect to attempt to reseat it and set a proper seal. However, the agency said that as engineers increased the pressure on the flow of liquid hydrogen into the core stage, the leak reoccurred.
"Engineers will attempt to reseat the seal in the quick disconnect cavity where the leak has been detected. This time they will stop flowing liquid hydrogen to the tank, close the valve used to fill and drain it, then increase pressure on a ground transfer line using helium to to try to reseal it," NASA wrote in a blog post.
