NASA Fuels Moon Rocket in Artemis I Test But Is Hit Again With Pesky Leaks

There was no immediate decision on whether NASA would try for a liftoff Tuesday given the sporadic nature of the hydrogen leaks, which have bedeviled the launch team for months.

Hydrogen leaks spoiled the first two launch attempts, as well as earlier countdown tests. So much hydrogen escaped during the countdown earlier this month that it exceeded NASA’s limit by more than double. Wednesday's leak almost got that big again.

Following the Sept. 3 launch delay, NASA replaced two seals in the leaky line. One seal had a tiny indentation; it measured a mere one-hundredth of an inch. NASA also altered the fueling process, easing slowly into the loading of the super-cold liquid hydrogen and oxygen. After Wednesday's big leak appeared, the launch team moved even more slowly to subject the plumbing to even less stress.
