Juno

(New Frontiers 2, NF2)
(mission to Jupiter)

Juno (New Frontiers 2 or NF2) 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.

Upon reaching Jupiter in July 2106, the spacecraft was inserted in a 53-day orbit, an event called Juno Orbit Insertion or JOI. The original plan included a shift to a 14-day orbit, for 37 orbits in all, but the plan was revised due to equipment issues. The revised plan was for 12 53-day orbits, followed by destruction the spacecraft in Jupiter's atmosphere in July 2018. However, with the spacecraft still healthy in Summer 2018, the mission has been extended to 2021.
