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.

When will the extended mission be approved or not approved?
Knowing we have a chance to study Europa in the next three years has my nerves on overdrive. |

When will the extended mission be approved or not approved? The decision is expected in December. Perhaps more important than simple approved or not approved (it seems unlikely that NASA will shut the mission down on its first extended mission request), is the budget. A smaller budget than requested could mean less is done. NASA has a fixed pot of money to fund all of its extended planetary missions, and I'm sure that the managers for the other missions are also making compelling cases for their science. -------------------- |
