INTERNATIONAL NEWS - US entrepreneur Elon Musk has launched his new rocket, the Falcon Heavy, from the Kennedy Space Center in Florida.
The mammoth vehicle - the most powerful since the shuttle system - lifted clear of its pad without incident to soar high over the Atlantic Ocean.
It was billed as a risky test flight in advance of the lift-off.
The SpaceX CEO said the challenges of developing the new rocket meant the chances of a successful first outing might be only 50-50.
"I had this image of just a giant explosion on the pad, a wheel bouncing down the road. But fortunately, that's not what happened," he told reporters after the event.
With this debut, the Falcon Heavy becomes the most capable launch vehicle available.
