An Interactive Guide To The Juno Spacecraft

Meet the 12-foot-tall behemoth that's about to arrive at Jupiter

The Juno spacecraft will arrive in Jupiter's orbit on July 4th to give us our closest-ever views of the most extreme planet in the solar system.

Scroll over the images below to learn more about some of the spacecraft's most important parts.
