Finally, the spacecraft is scheduled to perform two flybys of Io in 2024 at a distance of 1,500km (930mi). Aside from taking the first close-up pictures of the planet, the probes discovered its magnetosphere and its largely fluid interior. These probes make Jupiter the most visited of the Solar System's outer planets as all missions to the outer Solar System have used Jupiter flybys. Thus there may have been several generations of Galilean-mass satellites in Jupiter's early history. e. the fuel) at launch, at the cost of a significantly longer flight duration to reach a target such as Jupiter when compared to the direct trajectory.

The partnership for the Europa Jupiter System Mission has since ended, but NASA will continue to contribute the European mission with hardware and an instrument. Juice’s continuous observations of the gas giant will give us a better chance of seeing them – and learning how Jupiter’s atmosphere responds – than we’ve ever had before. The two small moons Adrastea and Metis orbit here within the main ring and are thought to be the source of dust of this ring.day orbit was planned to be maintained through July 2018 for a total of twelve science-gathering perijoves. The plaque depicts a portrait of Galileo and a text in Galileo's own handwriting, penned in January 1610, while observing what would later be known to be the Galilean moons. Juno 's mission is to measure Jupiter's composition, gravitational field, magnetic field, and polar magnetosphere. When heating levels had dropped below predetermined limits, the payload fairing that protected Juno during launch and transit through the thickest part of the atmosphere separated, about 3 minutes 24 seconds into the flight. The desire for a Jupiter probe was strong in the years prior to this, but there had not been any approved missions.

They also took the first close-up images of the planet's atmosphere, revealing the Great Red Spot as a complex storm moving in a counter-clockwise direction. This is comparable to the previous Galileo mission that orbited Jupiter, which captured thousands of images [106] despite its slow data rate of 1000 bit/s (at maximum compression level) due to the failure of its high gain antenna.Ganymede has a high number of craters, but many are gone or barely visible due to its icy crust forming over them.
