NASA's new moon rocket could face more launch delays, this time because of tropical weather. An approaching storm may force NASA to not only delay next week's launch attempt, but also move the rocket from its Florida pad and back into the hangar. Managers said Friday that barring weather, the rocket is ready to blast off Tuesday on its first test flight after a fueling test earlier this week. But a tropical depression in the Caribbean is moving toward Florida and could become a major hurricane. NASA says it will keep monitoring the forecast and decide no later than Saturday on how best to proceed. It takes three days of prep to haul the rocket back to the hangar.
