CAPE CANAVERAL, Fla. (AP) — NASA called off the launch of its mighty new moon rocket on its debut flight with three test dummies aboard Monday after a last-minute cascade of problems culminating in unexplained engine trouble.

The next launch attempt will not take place until Friday at the earliest and could be off until mid-September or later.
