• NASA's SpaceX, Boeing deal a giant leap for space flight

The California company called off its early Saturday liftoff from Cape Canaveral, with a half-hour remaining in the countdown. Officials said they will try again Sunday to launch the unmanned Falcon rocket.

The SpaceX Dragon capsule holds 2,268 kilograms (more than 5,000 pounds) of space station cargo for NASA, including a 3-D printer. NASA hopes astronauts will be able to one day fix their spacecraft by cranking out spare parts on the spot.

This will be the fifth station shipment by SpaceX.

It's been an exciting week for SpaceX. On Tuesday, the company won a huge contract to deliver U.S. astronauts to the space station.
