NASA called off today’s attempt to launch its Space Launch System rocket due to a hydrogen leak encountered during the process of fueling up the core stage.
The next opportunity for liftoff could come on Sept. 5 or 6, but NASA hasn’t yet decided the timing for the third launch attempt.
NASA’s uncrewed test mission, known as Artemis 1, is meant to blaze a trail for sending astronauts to the moon.
“We’ll go when it’s ready,” NASA Administrator Bill Nelson said. “We don’t go until then, and especially now, on a test flight, because we’re going to stress this and test it … and make sure it’s right before we put four humans up on the top of it. So, this is part of the space business.”
Today’s scrub at Kennedy Space Center in Florida came five days after an initial postponement, which was attributed to concerns about the procedure for cooling down the SLS’s rocket engines prior to launch.
