Juno will fly over Europa and Io tori, the ion ring cloud, at various times, characterizing the radiation environment near these satellites in order to better prepare the Europa Clipper and JUICE missions to optimize their observation and observation strategies. Plan scientific priorities and design missions.Additional missions also add planetary geology and ring dynamics to Juno’s comprehensive list of scientific investigations.
The natural evolution of Juneau’s orbit around the gas giant provides many new scientific opportunities that the mission extends. All science lines send a solar-powered spacecraft low-zoom above Jupiter’s cloud tops, collecting data from a unique vantage point that no other spacecraft has ever loved.
The point between each orbit where Juno comes closest to Earth is called the perijove (or PJ). During the mission, Juno̵7;s perijoves migrated northward, greatly improving the resolution of the northern hemisphere. The extended mission design takes advantage of the continuous northern migration of these perijoves to increase the view of the multiple cyclones that surround the North Pole while incorporating Galilee’s rings and moons.
“Gravity is assisted by multiple satellites to control our spacecraft through the Jovian system while providing many scientific opportunities,” said Ed Hirst, Juno program manager of JPL. Total number of scientific orbits that can be obtained “
The satellite encounter began with Ganymede’s low altitude flight on June 7, 2021 (PJ34), which would shorten the orbital time from approximately 53 days to 43 days. It made a close flight over Europa on 29 September 2022 (PJ45), reducing the orbiting time to 38 days. (PJ58) combined to shorten the orbital time to 33 days.
