IAPS instruments and projects for Solar System's exploration

About Juno

Juno is a NASA mission that will conduct an in-depth study of Jupiter, the most massive planet in our solar system. Juno was launched on August 2011 and will arrive at Jupiter in 2016, when it will be farther from the sun than any previous solar powered spacecraft.

Scientific Goal

Juno’s scientific goal is to understand the origin and evolution of the gas giant planet, which will pave the way to a better understanding of our solar system and other planetary systems being discovered around other stars. Juno will allow us to examine Jupiter from its innermost core to the outer reaches of its enormous magnetic force field. During its mission, Juno will map Jupiter’s gravity and magnetic fields to learn what the planet’s interior structure is like. The spacecraft also will observe the composition and circulation of the deep atmosphere and improve our understanding of the forces that control the planet’s powerful auroras. In addition to expanding our knowledge of the solar system’s largest planet, these investigations will provide clues about what conditions in the early solar system were like when Jupiter was forming. Improving our knowledge of Jupiter’s origins and evolution will also help us to better understand the many planetary systems being discovered around other stars. To do this, Juno carryies a series of scientific instruments, among which Jiram.

Juno scientific instruments

The Juno mission’s science objectives will be achieved with a payload of seven instruments onboard the spacecraft, designed to collect key new data. A camera for Education and Public Outreach called JunoCam will also provide a visual context for the Jupiter observations, especially of the North Polar region. The science investigations and supporting instruments are well summarized in the picture below.
