Voting
Welcome!
Juno is in a 53-day orbit. When it passes close to Jupiter (“PeriJove”
or “PJ”) we will take as many pictures as we can. The number of pictures that we take is
limited by the amount of onboard data storage that we have for JunoCam, so we
have to be selective. The images are
collected as we go from the north pole of Jupiter to the south pole, which
happens in a brief 2 hour portion of the orbit.
On any given perijove pass we will only be able to image targets in a
narrow swath of territory the spacecraft flies over (“groundtrack”).
Juno’s orbit geometry is evolving so we will carry out campaigns rather than voting on specific targets. Campaigns are focused on a specific science theme and take advantage of the changes in lighting.

What happened to Voting?
Up through PJ8 everyone could vote on their favorite Point
of Interest (POI) and those rounds can be viewed here. Changes in the orbit and mission plan mean
that we are no longer selecting targets by vote.
There will still be a voting page for every orbit and we will describe the specifics of each perijove pass such as the spacecraft orientation. Because of the challenges to predict the Points of Interest that will be in the JunoCam field of view we are now timing the image collection by latitude and/or executing campaigns.

Target Selection
We will take polar images on every PJ pass to assemble
timelapse sequences to study the dynamics of the circumpolar cyclones. Between the north and south pole images will
be timed to get complete latitudinal coverage.
The rest of the resources will be used for campaigns. Options are to look for lightning, take multiple methane images to study high altitude hazes, study Jupiter’s ring, take stereo pairs for cloud altitudes, image Galilean moons when available, etc. We will keep the Voting Round discussion for comments on what would be best. We are hoping that you enjoy being a part of this process, that you enjoy being a member of the JunoCam team.

PJ8 Encounter
CLOSED : 2017-08-24 17:00:00
Perijove on : 2017-09-01 21:50 UT
Juno's orbit around Jupiter is evolving. This is the last full opportunity to image Jupiter from 5 days out to 5 days after perijove. We will want to take advantage of this last chance for continuity at every latitude. That said, we do have a large data volume available for the perijove pass, so we will probably be able to capture most of the Points of Interest you vote for. We have also set aside a small number of bits for a nice image of Io.
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.
PJ8: We have sufficient on-board data storage to take the top 24 of 27 suggested sites. This is in part because we merged a number of targets that were close together in latitude, so the total number of images of POI's to be acquired (not including our routine polar images) is 17. Adding in polar images we will be acquiring 23 images as Juno races from the north pole to the south pole.
Changes are looming for this Voting task. PJ9 will take place in solar conjunction when Jupiter is behind the sun as seen from the earth. There will be no ground-based images to predict where Points of Interest will be. We are in the same situation for PJ10 as Jupiter is still too close to the sun for earth-based observers to image.
Juno's orbit is evolving. We refer to an elliptical orbit as a "petal". As Jupiter travels around the sun the orbit petal rotates toward midnight, such that most of the time JunoCam sees only a crescent Jupiter if at all. Juno will still make a perijove pass however JunoCam may be looking sideways from its mount parallel to the solar panels. Jupiter will be in the field of view at the poles, but it will be offset from the boresight during the close part of the pass.
We will post the images for you to process and we'll maintain the Planning and Discussion webpages. Keep an eye on the Voting page to see what it will be replaced with in the future.

Dear NASA; Juno Mission; as far as I understand, the JUNO CAM Tool is taking a high resolution images from Planet Jupiter. What we are seeing is a Map of atmospheric formations that are constantly moving and changing. Can you show approximately what part of the Jupiter hard surface or Jupiter land is actually visible? Or we are seeing just a clouds and atmospheric formations on those Maps?
Wonderful, I suggested Io a little while ago. How close will JUNO get to Io and what sort of resolution of the volcanic moon will we get?
Great work NASA! THANK YOU!
