reaching Jupiter today

juno20150225Launched from Earth in August 2011, the Juno probe is due to arrive at Jupiter on July 4, 2016. Once there, it will circle Jupiter 37 times, observing its atmosphere and magnetic fields, before plunging into the giant planet so as not to contaminate Europa with microbes.

Juno’s principal goal is to understand the origin and evolution of Jupiter. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars.

With its suite of science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras.

Juno will let us take a giant step forward in our understanding of how giant planets form and the role these titans played in putting together the rest of the solar system.
