Juno: Unlocking Jupiter's Mysteries
Juno will improve our understanding of the solar system's beginnings by revealing the origin and evolution of Jupiter. Specifically, Juno will:
- determine how much water is in Jupiter's atmosphere, which helps to determine which planet formation theory is correct (or if new theories are needed)
- look deep into Jupiter's atmosphere to measure composition, temperature, cloud motions and other properties
- map Jupiter's magnetic and gravity fields, revealing the planet's deep structure
- explore and study Jupiter's magnetosphere near the planet's poles, especially the auroras—Jupiter's northern and southern lights—providing new insights about how the planet's enormous magnetic force field affects its atmosphere.
