B-roll for media. Juno's goal is to understand the origin and evolution of Jupiter. The spacecraft launched Aug. 5, 2011, and will orbit the giant planet more than 30 times, skimming to within 3,000 miles (5,000 kilometers) above the planet's cloud tops every 14 days. During the flybys, Juno will probe beneath the obscuring cloud cover of Jupiter and study its auroras to learn more about the planet's formation, structure, atmosphere and magnetosphere.
