The launch of the NASA Artemis I rocket was scrubbed for a second time on Saturday after another fuel leak.
Artemis Launch Director Charlie Blackwell-Thompson finally halted the countdown at 11:17 a.m. EDT after three to four hours of effort.
The team then started to work to de-tank the rocket.
Launch controllers were unable to troubleshoot a hydrogen leak – which was detected at 7:15 a.m. EDT – that reoccurred twice in a cavity between the ground and flight side plates of a quick disconnect.
Engineers had attempted to reseat the seal in the quick disconnect cavity where the leak occurred by applying pressure to it with helium.
