The Juno Space craft is on a mission to Jupiter, to study the planet's atmosphere and magnetic fields. The spacecraft launched in August 2011 and will finally reach its destination in July 2016.
Throughout its journey, the spacecraft will rely on solar power, even when it's 484 million miles away from the sun. Famed science guy Bill Nye explains how it will do this and demonstrate just how energy efficient the Juno Spacecraft is.
