A NASA robotic mission that has orbited Jupiter since 2016 to study the planet's composition, gravity and magnetic fields, and deep atmospheric structure. Launched on 5 August 2011, the Juno spacecraft entered a polar orbit of Jupiter on 5 July 2016 and has had its mission repeatedly extended, continuing observations of the planet and its major moons into the mid-2020s.

Data from the Juno mission showed that Jupiter has a diffuse core that mixes into its mantle, extending for 30-50% of the planet's radius, and comprising heavy elements with a combined mass 7-25 times the Earth.

These observations were later supported by Juno, which detected various salts and other compounds on Ganymede's surface, including hydrated sodium chloride, ammonium chloride, sodium bicarbonate, and possibly aliphatic aldehydes.
