(mission to Jupiter)

Juno is a space mission to Jupiter launched in 2011, which reached Jupiter orbit in 2016, and is studying Jupiter's Gravity, composition, Magnetic Field, and polar Magnetosphere. It is NASA's second New Frontiers mission. Among its goals is data regarding the nature of Jupiter's Atmosphere, i.e., to help determine whether Shallow Atmosphere Models or Deep Atmosphere Models apply. Data is consistent with models with winds 3000km deep.

The spacecraft is in a 53-day polar orbit, with 12 such orbits planned before the craft is destroyed in Jupiter's atmosphere in July 2018. The original plan included a shift to a 14-day orbit, for 37 orbits, but the change was canceled due to equipment issues.
