Juno Arrives To Check On Jupiter's Affairs

Jupiter - the Roman God of the Sky and Thunder, King of the gods, and the name given to the largest planet in our solar system. It's a planet so large that, not including the sun, the rest of the solar system would fit inside with plenty of room to spare.

Jupiter's moons are named after the god's many lovers. According to mythology, when Jupiter thought his wife suspected him of cheating, he turned himself into a cloud to cover his affairs.

Now, NASA has sent the Juno Spacecraft, named after Jupiter's wife, to discover just what Jupiter has hidden beneath its clouds.

'Star Trackers' Help Juno Find Its Way

Space navigation is tricky. There's no up or down, no left or right, and no road signs. This device uses stars to help determine if a spacecraft is off course. It takes nifty pictures, too.
