CAPE CANAVERAL, Fla. — An attempt to send the Artemis One moon rocket into space is being scrubbed once again.
NASA cited a hydrogen leak as the reason why. A previous attempt was postponed on Monday.
Launch director Charlie Blackwell-Thompson and her team tried to stop the leak the way they did the last time, which included stopping and restarting the flow of super-cold liquid hydrogen in hopes of removing the gap around a seal in the supply line.
They tried this method twice, but the leak persisted, forcing them to once again scrub the planned launch.
A similar issue happened on Monday, but turned out to be a faulty temperature sensor in one of the main rocket’s engines.
It’s not clear when NASA plans to try and launch again.
