After a journey lasting some 5 years and nearly 3 billion kilometres, the NASA spaceship Juno is nearing its final destination – the huge planet Jupiter which orbits the Sun between Mars and Saturn.
On the 4th of July, the probe will arrive – and if all goes to plan – start taking measurements that scientists hope will reveal important clues about the creation of our solar system.
Robin McKie is the Science Editor of The Observer. He has been looking at the challenges Juno faces in making its final approach to Jupiter, and what it could find when it gets there.
