Celebrate the 4th: Watch NASA's Juno Start Its Jupiter Research Tonight

Juno tops off a 5 year Journey to Jupiter

Watch live on USTREAM the historic Juno insertion into Jupiter orbit
Watch Juno insert itself into a Jupiter Polar Orbit

Tonight at 7:30PM PT on USTREAM, you can watch Juno's insertion into the Jupiter Polar Orbit. From a unique polar orbit, Juno will repeatedly dive between the planet and its intense belts of charged particle radiation, coming only about 3,000 miles (5,000 kilometers) from the cloud tops at closest approach.
From NASA's website, Juno's primary goal is to improve our understanding of Jupiter's formation and evolution. The spacecraft will investigate the planet's origins, interior structure, deep atmosphere and magnetosphere. Juno's study of Jupiter will help us to understand the history of our own solar system and provide new insight into how planetary systems form and develop in our galaxy and beyond.

Mission of Firsts

• First space mission to operate a solar-powered spacecraft at Jupiter 
• Farthest solar powered spacecraft from Earth 
• First space mission to orbit an outer-planet from pole to pole 
• First space mission to fly as close as 2,600 miles to Jupiter’s cloud tops 
• First mission to be designed to operate in the heart of Jupiter’s radiation belts 
• First mission to carry a titanium radiation vault to protect the spacecraft’s mostsensitive instruments from a planet’s intense belts of radiation 
• First spacecraft to fly 3D-printed titanium parts (Waveguide brackets) 
• Will be the fastest spacecraft to enter orbit around a planet, at 130,000 mph (129,518 mph/57.9 km/s) relative to Earth 
• Will take the highest-resolution images of Jupiter in history
