The Juno mission is currently in Phase A Concept Study as a candidate for the next NASA New Frontiers program investigation.
The overarching scientific goal of the Juno mission is to understand the origin and evolution of Jupiter. As the archetype of
giant planets, Jupiter can provide the knowledge we need to understand the origin of our own solar system and the planetary
systems being discovered around other stars. Juno's investigation of Jupiter focuses on four themes: Origin, Interior
Structure, Atmospheric Composition and Dynamics, and the Polar Magnetosphere.
The mission is a Jupiter polar orbiter which uses a spinning spacecraft to make global maps of the gravity, magnetic fields,
and atmospheric composition of Jupiter from a unique polar orbit with a close perijove. Juno's 32 orbits extensively sample
Jupiter's full range of latitudes and longitudes. High sensitivity radiometric measurements thus yield a 3-dimensional view
of Jupiter's deep atmosphere (down to ~100bars) to infer the bulk abundance of water, which could not be derived from Galileo
data, and understand its complex meteorology. Determining water abundance permits discrimination between various scenarios
of the formation of Jupiter. The radiometry will also confirm the global ammonia abundance. The gravity data constrain the
planet's interior rotation and structure. The precise magnetic field measurements are used to infer how the interior dynamo
works and generates the most powerful magnetic field of planets in the Solar System. From its polar perspective Juno combines
in situ and remote sensing observations to explore the polar magnetosphere and determine what drives Jupiter's remarkable
auroras. Without landers, probes, or returned samples, the mission has extremely low risk.
