Juno is now 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”).
We are inviting you to participate in this selection process. Each perijove we will tell you if there are any special constraints, special opportunities, or unique goals we are trying to meet. We will set aside data volume for 2 polar images. Then we will invite you to prioritize the points of interest, and we will image as many as we can, based on your priorities.
There will be a voting page for every orbit and we will highlight the Points of Interest (POI’s, defined on the Discussion page) that will be within the JunoCam field of view. Voting will usually be open for 6 days, although that schedule may be modified for holidays. The number of votes that a POI gets will determine its priority. Your comments, your advocacy for a particular POI, will help to get it selected!
Votes for any particular round may be re-assigned until voting closes for that round.
The target prioritization and selection process is ordinarily done by an imaging science team in a conference room or on a telecon. Each scientist argues for their top candidates and says why they are important.
In general we are holding back enough data volume for 2 polar images. Occasionally we will also set aside some data volume for a unique image of a Galilean satellite. All the rest of the data volume will be used to target images in the priority determined by the voting.
You will be a participant in the discussions we would otherwise have off-line. The Juno science team will be weighing in with their wishes, but they will have to advocate and convince you to vote for their favorites. We are hoping that you enjoy being a part of this process, that you enjoy being a member of the JunoCam team.
