This topic will consist of discussion of Juno operations post-JOI until end of mission, currently anticipated in Feb 2018.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Let's not forget that Pioneer 11 got our first half-decent look at Jupiter's north pole, and it didn't spy anything hexagonal.

Keep in mind that Jupiter's cloud deck is very deep, and whatever we see from space looking down is just one layer. My understanding is that the jovian poles show us a layer of haze that overlies the cloud layer that we see elsewhere. So, we're not merely looking at the ammonia clouds we see at other latitudes and seeing how they vary with latitude – we're seeing a different layer altogether.
https://www.eso.org/public/usa/images/eso0123e/ So, we may very well not have a chance to see whatever Jupiter has at an altitude comparable to Saturn's hexagon, so long as we look in visible light. This recapitulates the reasons why Juno isn't just a "pretty pictures" mission and why JunoCam is a ride-along instrument while other instruments do the real science. It's a pretty good bet that Jupiter has some different-looking maps at different depths and Juno will give us a peek at that, but JunoCam will not. The thing I'd like to know is whether Jupiter's banding is upper layers only, or "bands all the way down," or "cylinders all the way down." I'm not sure how much we'll find out as Juno's mission proceeds or if we'll get a bonanza of results released all at once when the whole mission is done. The microwave spectrometry is going to take some time to process and interpret, and the gravity / radio science is going to accumulate over time. |
