SpaceX rocket explodes at Cape Canaveral ahead of launch

In a statement, the company blamed the blast on "an anomaly" and said no-one had been injured.

It said the rocket's payload, a satellite due to be launched on Saturday, was also destroyed.

The force of the blast shook buildings several miles away and sent a plume of smoke high above the complex.

SpaceX is seeking to create a new era of reusable rockets and affordable private space travel and has used its Falcon-9 rocket to take supplies to the International Space Station (ISS).

In December last year, the California-based company successfully landed a Falcon-9 back on Earth after a mission to launch orbiting satellites - a first in rocketry.

It went on to recover five more boosters, with most of them returning to an ocean platform.

The idea is to re-fly these rockets, and the first such "second hand" vehicle is scheduled to launch in October.

SpaceX is run out of Hawthorne near Los Angeles by Elon Musk, who made his fortune with internet companies.

As well as being the rocket company's CEO, he also heads up the Tesla electric car company.
