MIAMI (Web Desk): SpaceX Rocket blasted off its Falcon 9 rocket carrying the unmanned Dragon cargo ship, packed with food and supplies for the six astronauts living at the International Space Station.

The white rocket soared into the cloudy, gray skies over Cape Canaveral, Florida. The mission was the first to take off from NASA s historic launchpad 39A, the origin of the pioneering US spaceflights that took astronauts to the Moon in the 1960s and 1970s, as well as the space shuttle missions that ran from 1981 to 2011.

The launch was initially planned for Saturday, but was cancelled just 13 seconds before liftoff due to a glitch with the rocket engine. "They resolved all the technical issues last night," said NASA s Bob Cabana, director of Kennedy Space Centre.

The origin of the problem - a piece of equipment known as the thrust vector control actuator in the second stage - was replaced. Subsequent tests showed it was working fine, a SpaceX spokesman explained. The unmanned spaceship is packed with more than 2,267 kilogrammes of food, gear and science experiments for the astronauts in orbit.

It is the 10th such resupply mission for SpaceX , which along with Orbital ATK has a multi-year contract with NASA to send supplies to the International Space Station. The cargo is expected to arrive at the space station on Feb 22, a SpaceX spokesman said.

About 10 minutes after the launch , SpaceX refired the engines on the booster portion of the Falcon 9, guiding it down to a controlled, upright landing at a different part of Cape Canaveral.
