NASA reaching a milestone years in the making.

FOX's Jack Callaghan reports:

Cheers at NASA's Jet Propulsion Laboratory in Pasadena, California, as the Juno space probe phoned home that it had successfully begun to orbit the planet Jupiter.

It's taken five years and one billion 800 million miles to get there. Eventually, the hope is Juno will take some pictures: 

(Green) "We will be taking images of the aurora, the fabulous polar auroras, the cloud structures, the 'Great Red Spot', we'll be seeing some pretty spectacular stuff." 

Jim Green is NASA's planetary science director. Juno will spend two years in snapping pictures and gathering data about the largest planet in the solar system before crashing itself into Jupiter in 2018.
