Fuel leak interrupts launch countdown of NASA moon rocket

Early Monday, a fuel leak recurred during NASA's countdown for the launch of its new moon rocket

disrupting the countdown in the same spot where seepage had occurred earlier in the spring.

Launch controllers stopped the fueling procedure because it was already running an hour behind schedule due to thunderstorms offshore. 

The countdown would almost surely finish if the hydrogen fuel leak got worse

they gently restarted the procedure, but alarms caused another pause.

The 322-foot (98-meter) rocket outperforms even the Saturn V, which sent people to the moon fifty years ago, in terms of power.

If this test mission is successful, it would be the first crewed spacecraft to orbit the moon in 50 years.
