This week in 2011, the Juno spacecraft was launched from Cape Canaveral Air Force Station aboard an Atlas V rocket to begin a five-year journey to Jupiter. Juno’s principal mission is to orbit Jupiter’s poles to find out more about the gas giant’s origins, structures, atmosphere and magnetosphere, and investigate the existence of a solid planetary core. Here, the spacecraft is tested for center of gravity, weighing and balancing on the rotation stand in Astrotech’s payload processing facility in Titusville, Florida. The Juno mission is part of the New Frontiers Program, managed at NASA’s Marshall Space Flight Center for the agency’s Science Mission Directorate. The NASA History Program is responsible for generating, disseminating and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA’s activities in aeronautics and space.
