The Juno spacecraft, currently making its way to Jupiter, will for the first time peer below Jupiter's dense cover of clouds to answer questions about the gas giant and the origins of our solar system.
Juno's primary goal is to reveal the story of Jupiter's formation and evolution. Using long-proven technologies on a spinning spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter's gravity and magnetic fields, atmospheric dynamics and composition, and evolution.
