NASA said it needs to replace hydrogen-fueling equipment on its new moon rocket after scrubbing the launch for the second time in a week, a decision that means the spaceship won’t fly until at least late September.

“I look at this as a part of our space program, of which safety is the top of the list,” NASA administrator Bill Nelson said at an afternoon press conference where officials explained that engineers tried multiple times to stop a hydrogen leak. Some hardware will be replaced, and one of the options being considered to do that involves moving the rocket back to the massive Vehicle Assembly Building -- which would delay the mission by several weeks.
