CAPE CANAVERAL, Fla. -- The SpaceX Dragon capsule has developed a problem on its way to the International Space Station.
The trouble cropped up nine minutes after Friday's launch from Cape Canaveral.
SpaceX's billionaire founder Elon Musk is reporting via Twitter that there's a problem with the thrusters on the spacecraft. He says flight controllers are trying to override the system and fix the problem.
Musk is monitoring the flight from SpaceX Mission Control in California.
More than 1 ton of space station supplies is aboard the Dragon. It's supposed to arrive at the space station Saturday morning.
