The Juno spacecraft, which successfully entered the orbit of Jupiter on July 4, 2016, will for the first time peer below the 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.
Launch - August 5, 2011
Deep Space Maneuvers - August/September 2012
Earth flyby gravity assist - October 2013
Jupiter arrival and orbit insertion - July 4, 2016
End of mission (deorbit into Jupiter) - Juno will continue to operate within the current budget plan through July 2018, for a total of 12 science orbits. The team can then propose to extend the mission during the next science review cycle. For more information, go to: https://www.jpl.nasa.gov/news/news.php?feature=6752
