Description
NASA's Juno mission uses a polar Jupiter orbiter to determine how the giant planet formed and evolved, while measuring its deep atmosphere, gravity field, magnetic environment, aurorae, and magnetosphere.
Destination
Long, looping polar orbit around Jupiter, diving to approximately 3,500 km above the cloud tops and extending beyond Callisto’s orbit, for studying Jupiter’s origin, interior, atmosphere, magnetic field, aurorae, and moons
Launch Site
Outcome
Juno entered Jupiter orbit in July 2016 and revealed organized polar cyclone systems, atmospheric winds extending deep below the visible clouds, and a complex magnetic environment. Its extended exploration includes close observations of Jupiter's major moons, including volcanic activity and lava lakes on Io. The solar-powered orbiter continues to investigate Jupiter's interior, atmosphere, aurorae, and surrounding space environment.
