SpaceX's unmanned Dragon cargo ship blasts off toward the International Space Station, carrying a load of supplies and science experiments for the astronauts living there.

The spacecraft launched aboard a Falcon 9 rocket from Cape Canaveral, Florida at 1:52 am (0552 GMT).

It is scheduled to arrive at the ISS early Tuesday. The journey to the ISS is the fifth for SpaceX, and the fourth in a series of SpaceX's contracted supply missions with NASA.
