Voting Round :

PJ5 Encounter

About This Round
The entire perijove pass from the north pole to the south pole will be open for voting. We will however set aside a larger portion of the data volume for polar time lapse sequences to see the circumpolar cyclones rotate.
Perijove Predict Map
About Perijove Predict Maps

Every perijove pass we have the challenge of predicting where Points of Interest will be as the different zones of the planet have different wind velocities. This map shows our effort to rotate the latitudinal zones with their different wind speeds to predict what will be under the Juno groundtrack.

Winner Selection
Once again you have selected our targets! We will be able to image 9 Points of Interest in the priority set by your votes.

We started the process of generating image commands as soon as the voting closed. We looked first at the predictions of what time an image would need to be taken to get a particular POI. We have constraints on how closely together we can take images, because an image must be moved from the camera to the spacecraft computer before we take the next one. That means if targets are closer together in time than 90 sec we combined them. We took the time that corresponded to the higher priority target, but we will get the other POI's in the image.

We then started planning images in priority order until we used up all the available data volume.

The list of POI’s we will image in order of the votes they received is as follows, with the “+” indicating targets we combined:

Double SEB
Trevmation’s Dark Spot
The Big Red Stripe
String of Pearls + Between the Pearls + An Interesting Band Point
STB Spectre + The White Solid

We are also picking up Covenant 151016 as part of the polar timelapse sequence.

These images will be available after we get "C kernels" which is a file with the spacecraft orientation as a function of time. This data is necessary for us to process the data before we put it on the website. It takes two days for us to get that data from the navigation team. Perijove is on Monday, March 27, so we expect to start posting the images on Wednesday, March 29.

    So sad, I will not see any Banding Boundary ! My dream will not come true... Perhaps next time...Good luck!

    My top three POIs were selected, that´s what I call one lucky round! Now all we can do is wait for the data from our small friend out there..

    Thank you for giving us the chance to play a small role in this whole mission!

    Philosophia has managed to convince me to vote for the Big Red Stripe and in addition I voted for Trevmation's Dark Spot. One merit of this is that this should also result in fairly good coverage of three additional targets immediately north/south of these two targets, i.e. "Turbulent Region in Upper Belt", "Banding Boundary" and "Zorro" ("Banding Boundary" should appear in both of these). It should also be possible to make a spectacular, big mosaic/map containing both of these observations.

    I love that I could place my votes on something this spectacular, Thanks for this!

    Thank you for allowing us to vote on this!!

    you cant say no to Zorro

    Spotty McSpotface.

    It's in the name people

    Any chance of showing us the "stripes" to be overflown in future perijoves? Would add to the fun trying to home image the target areas. Great mission.

    I chose the banding boundary, the white solid, and string of pearls. Each seems a type of feature representative of Jupiter: the bands, regions of differing colors and composition, different interactions, and of course storms.

    I don't like using big words. I am just happy NASA let us do this

      I'm also intrigued by the Double SEB. The third choice is tough - it would be so much fun to vote for SpottyMcSpotface, but I'd like to see Trevmation's Dark Spot up close.

      Philosophia you have convinced me to vote for the STB spectre!

    • comment by Rigel-7 on 2017-03-15 18:39 UT

      I vote to take pictures of areas that will most benefit science. Those areas of Jupiter that hold the most questions among scientists seems to me to be the best use of our time. Space is a dangerous place and the spacecraft could encounter a problem that cuts the mission short. Let's take advantage of every single photo opportunity to learn something. However, if all available choices are basically equal, then I vote to shoot some photos of locations that look relatively ordinary. Perhaps a closeup look at such ordinary-looking locations will reveal something extraordinary and something we didn't know. Including the public in this endeavor/discussion is an excellent idea; members of the next generation of scientists may well be among the participants here and who knows what they will discover/encounter. To those who are just starting out: grab every chance to be involved and make a difference.

      Do you think there should be an inner camera and view from the spacecraft? I am asking this because there are 3 LEGO Minifigures on the spaceship and would be really interesting to see them in the interior of the Spacecraft at Jupiter background? Thanks!

      Here is our predictive map:

    • comment by Philosophia-47 on 2017-03-15 00:20 UT

      May I make two top recommendations for voting:

      1) The STB Spectre [POI: ‘STB Spectre’]. This ghostly bluish streak is a long-lived cyclonic circulation which is one of the few structures perceptible in these whitened latitudes where the South Temperate Belt would normally be. The dark spot at the south-west end is where incoming small dark spots perform a U-turn. It has never been seen close up and it should be perfectly positioned at PJ-5. A methane-band image might also be worthwhile.

      2) The NTB(S) – the new orange belt [POI: ‘The Big Red Stripe’]. Since the great outbreak initiated the revival of this belt last autumn, we have a unique opportunity to monitor its progress. JunoCam already got fine images at PJ-3 and PJ-4; let’s continue the series to see how the belt is changing. (Ideally, image at the same latitude as before, i.e. +22.7 planetocentric, +25.5 planetographic).

      --John Rogers.
