CAPE CANAVERAL, Fla. (AP) — NASA kicked off a critical countdown test Friday for its new moon rocket, a 30-story behemoth that could make its first lunar test flight by summer.

The two-day demonstration — the final major milestone before liftoff to the moon — will culminate Sunday as teams load nearly 1 million gallons of super-cold fuel into the rocket on the pad. The countdown will halt at the 9-second mark before engines ignite.
