CAPE CANAVERAL, Fla. – A commercial craft carrying a ton of supplies for the International Space Station ran into thruster trouble shortly after liftoff Friday. Flight controllers managed to gain control, but were forced to delay its arrival at the orbiting lab.

The earliest the Dragon capsule could show up is Sunday, a full day late, said top officials for NASA and the private company SpaceX.

"We're definitely not going to rush it," said SpaceX's billionaire founder Elon Musk. "We want to make sure first and foremost that things are safe before proceeding."
