Juno's approach to the planet Jupiter.

NASA’s Juno Spacecraft is currently in orbit around Jupiter, following its five-year journey from Earth to study the Planet. But what is the Mission’s purpose, and what exactly will it be studying ?
Juno has travelled about 3 billion kilometres to get to Jupiter, launching in August 2011, performing an Earth fly-by in October 2013 and arriving at the Planet on 4 July 2016.
The Spacecraft will now begin orbiting The Gas Giant on a path that will take it over the Planet’s Poles. It will take fourteen days to complete each orbit and will do so thirty-seven times over the course of the Mission, flying low over Jupiter’s Cloud Tops as close as 4,100 km from the surface.
Ultimately, the Mission will seek to collect data to improve our understanding of how both Jupiter and The Solar System were formed and how they evolved.
Juno will attempt to determine how much water is in Jupiter’s atmosphere, which will tell NASA scientists a lot about how the Planet formed, and it will also measure the temperatures, cloud motions and composition of its atmosphere. It will spend time analysing Jupiter’s magnetic and gravity fields and exploring its magnetosphere, which will reveal information that will help scientists determine the Planet’s interior structure.
