NASA began fuelling its new moon rocket early Monday for liftoff on a test flight to put a crew capsule into lunar orbit for the first time in 50 years.
Thunderstorms delayed the fuelling operation by an hour. The threat of lightning diminished enough to allow the launch team to proceed with loading the rocket's tanks. But it was uncertain how much the stalled work might shorten the two-hour launch window.

No one was inside the Orion capsule atop the 322-foot (98-meter) rocket at Kennedy Space Center. Instead, three test dummies were strapped in for the lunar-orbiting mission, expected to last six weeks.
