NASA Re-plans Juno\u2019s Jupiter Mission<\/a><\/p>\nNASA has approved an update to Juno\u2019s science operations until July 2021. This provides for an additional 41 months in orbit around Jupiter and will enable Juno to achieve its primary science objectives.\u00a0 Juno is in 53-day orbits rather than 14-day orbits as initially planned because of a concern about valves on the spacecraft\u2019s fuel system. This longer orbit means that it will take more time to collect the needed science data.

As a bonus, the larger orbits allow us to further explore the far reaches of the Jovian magnetosphere — the region of space dominated by Jupiter’s magnetic field — including the far magnetotail, the southern magnetosphere, and the magnetospheric boundary region called the magnetopause. We have also found Jupiter\u2019s radiation environment in this orbit to be less extreme than expected, which has been beneficial to not only our spacecraft, but our instruments and the continued quality of science data collected.\u201d
