At today's Outer Planet Assessment Group (OPAG) meeting, Scott Bolton gave a presentation on Juno, providing an update on the mission and providing more information on its extended mission proposal. The proposal has been sent to NASA and they expect a final decision later this year.
The proposed extended mission starts where the current one ends at perijove 34 in June 2021 and continues through orbit 76 in September 2025. The continued northward progression of the perijove latitude, and continued lower altitude of the ascending node, is going to enable a lot of great science both at Jupiter (higher resolution views of Jupiter's poles) and of its satellites. Most excitingly for me, Juno will perform several flybys of the Galilean satellites. This includes a 1000-km encounter with Ganymede next June during PJ34, a 320-km encounter with Europa in late 2022, and TWO Io flybys in early 2024 at an altitude of 1500 km. There are also a number of "Voyager-class" encounters with Ganymede, Europa, and Io between mid-2021 and mid-2025.

Very excited to see Europa and Io!
Does Amalthea come close to being imaged? Very curious to the fallout from Io on its surface. |

Does Amalthea come close to being imaged? Juno gets to within 42000 km of Amalthea on 2025-07-13 but it will only be 8 pixels or so across. Remember that the encounters with the Galileans are as much about changing the orbit as about doing satellite science, and Amalthea is not useful for the former. -------------------- Disclaimer: This post is based on public information only.
