CAPE CANAVERAL, Fla. (AP) — A fuel leak and then an engine problem during final liftoff preparations led NASA to call off the launch of its mighty new moon rocket Monday on its debut flight with three test dummies aboard.
The next launch attempt will not take place until Friday at the earliest and could be off until next month.
The flight, when it happens, will be the first launch in NASA’s Artemis project, a quest to put astronauts back on the moon for the time since the Apollo program ended 50 years ago.
As precious minutes ticked away Monday morning, NASA repeatedly stopped and started the fueling of the Space Launch System rocket with nearly 1 million gallons of super-cold hydrogen and oxygen because of a leak of highly explosive hydrogen. The leak happened in the same place that saw seepage during a dress rehearsal back in the spring.
Then, NASA ran into new trouble when it was unable to properly chill one of the rocket’s four main engines, officials said. Engineers continued working to pinpoint the source of the problem after the launch postponement was announced.
