Abstract :
[en] Since its arrival in July of 2016, NASA's Juno spacecraft continues to return invaluable observations regarding Jupiter's dynamic magnetosphere. The polar orbiting spacecraft has an orbital period of 53.5 days, which takes it from just a few thousand kilometers above Jupiter's one-bar "surface" outward to over 100 jovian radii - cutting through Jupiter's polar region as well as its equatorial region. Although these regions are inherently coupled, in this talk we compartmentalize Juno's observations into the auroral and magnetospheric regions and briefly discuss their connections. One of Juno's primary science goals is to investigate the nature of Jupiter's aurora - the most powerful aurora in the solar system. Outfitted on the spacecraft are a suite of instruments dedicated to measuring the in situ plasma waves and magnetic fields, charged particles as well as remote sensing the ultraviolet and infrared signatures of the aurora. In concert, these observations have and continue to paint a fundamentally different view of the mechanisms producing the Jovian auroras. Juno's instruments are also sending back new and compelling observations of Jupiter's magnetospheric regions. Examples include: the discovery of a belt of heavy ions residing inside the main ring, new details regarding the magnetopause structure and dynamics, and a more comprehensive survey of the plasma sheet particle populations and dynamics. In this presentation we will briefly summarize some of the major findings from both the auroral and magnetospheric regions and discuss new mysteries and future anticipated observations from Juno.
