The launch of an unmanned SpaceX rocket — and an innovative attempt to land it on an ocean barge — were postponed on Monday due to poor weather at the Florida launch site, officials said.

The rocket, carrying a Dragon cargo ship bound for the International Space Station, had been slated to blast off Monday afternoon from Cape Canaveral Air Force Station, located just south of NASA's Kennedy Space Center.

Thick clouds and nearby rain showers scuttled the launch less than three minutes before liftoff. The flight was rescheduled for 4:10 p.m. EDT/2014 GMT on Tuesday.
