Extended Mission

Now in its extended mission, Juno remains NASA's most distant planetary orbiter, continuing its investigation of the solar system’s largest planet.  

The extended mission’s science campaigns expand on discoveries Juno has already made about Jupiter’s interior structure, internal magnetic field, atmosphere (including polar cyclones, deep atmosphere, and auroras), and magnetosphere. Jupiter’s enigmatic Great Blue Spot — an isolated patch of intense magnetic field near the planet’s equator – is the target of a high-spatial resolution magnetic survey during six flybys early in the extended mission. 
Juno’s extended mission includes flybys of the moons Ganymede, Europa, and Io.

Juno is now an explorer of the full Jovian system. As the spacecraft’s orbit continues to evolve, additional flybys of the moons Europa and Io are planned. Juno will also fly through the Europa torus and the Io torus. These are doughnut-shaped clouds of charged particles that surround each moon’s orbit. The spacecraft will pass through the tori on multiple occasions, characterizing the radiation environment near these satellites to better prepare NASA’s future missions. The extended mission also adds a study of dust in Jupiter’s faint rings to Juno’s extensive list of science investigations.
