   How will Juno affect Jupiter?

   • Juno will measure the amount of water and ammonia in Jupiter’s atmosphere and help determine if the planet has a core of heavy elements, constraining models on the origin of this giant planet and thereby the solar system.

   Does Juno orbit Jupiter?

   • Because of Juno’s ever-changing orbit, the spacecraft has traversed practically all regions of space near Jupiter. ASC data suggests that there is more very high-energy radiation relative to lower-energy radiation near Europa ’s orbit than previously thought.

   Could Juno's Radiation-protected sensors reveal how Jupiter formed?

   • Juno’s radiation-protected sensors show us Jupiter in greater detail than ever before. The mission could help to uncover how Jupiter formed, in turn shedding light on how the solar system, and maybe even life itself, came to be.

   How would radiation affect Juno's solar panels?

   • To see how radiation would affect Juno’s solar panels, engineers put the cells in what Rudolph describes as a “hot dog”-shaped chamber that fires electrons at the cells. Those experiments showed that the solar cells would lose 10 to 15 percent of their output over the life of the mission.

   How will Juno's radio signal affect Jupiter's magnetic field?

   • The Doppler shift in Juno's radio signal will allow scientists to map variations in Jupiter's gravity field as the spacecraft falls past the planet during each orbit. Juno's magnetometer will visualize Jupiter's magnetic field in 3-D, all around the planet, sensing the deep interior and watching for changes over time.

   Why is Juno watching Jupiter from orbit?

   • Like its mythical namesake, the planet Jupiter guards its secrets with jealous pride, its bulk swaddled in thick clouds. For the last six years, though, a spacecraft bearing Juno’s name has watched Jupiter from orbit, stripping away its secrets and furnishing new insights into its interior and evolution.

    HOW MUCH RADIATION? Juno is going into one of the harshest regions in the solar system – Jupiter’s radiation belts. Sure, Jupiter’s radiation is bad, but how bad can it really be? Outside the vault the spacecraft is expected to receive the equivalent of more than 100-million dental x-rays.
