CAPE CANAVERAL, Fla. (AP) — A fuel leak and then an engine problem during final liftoff preparations led NASA to scrub the launch of its mighty new moon rocket Monday morning on a shakedown flight with three test dummies aboard.

The next launch attempt will not take place until Friday at the earliest.
