A $1.1bn (£0.7bn) unmanned space mission has launched from Florida on a journey to the planet Jupiter.

The Juno spacecraft will cruise beyond Mars to put itself in orbit around the gas giant in 2016.

It is the first solar-powered mission to venture this far from the Sun.

The Atlas 5 rocket launched from Cape Canaveral Air Force Station after a brief delay caused by a helium leak.
