An approaching storm threatens to delay NASA's next launch attempt for its new moon rocket, already grounded for weeks by fuel leaks.
A tropical depression in the southern Caribbean is moving toward Florida and could become a major hurricane.
Managers on Friday declared that the rocket is now ready to blast off on its first test flight, after overcoming more hydrogen leaks during a fuelling test earlier in the week. It will be the first time a crew capsule orbits the moon in 50 years; the spacecraft will carry mannequins but no astronauts.
