I know this mission is not meant to study any Jovian satellites, but is Juno going to, by chance, pass near enough to any satellites (particularly small, not well imaged satellites) that it could take any useful pictures of them? (Or will it be possible to finagle the final de-orbit burn to send it past a satellite for this purpose?)

At the press briefing it was stated that although Juno will not get close to Jupiter's moons it will be taking pictures and because of it's polar orbit will get never before seen looks at the moons.

In the Planetary Radio talk I've referenced, Candy Hansen mentioned, that Juno is planned to get close to one of the Ring moons. But since those moons are tiny, the moon is expected to show up as a small spot only.
--- Might be, that positional data of the moon can be refined this way.

[I'd think, this thread should better be merged to the Jupiter approach thread.]

We may get some observations of satellites, but it's not the focus of the mission, and anything we obtain will probably not rival anything obtained by a previous mission regarding spatial resolution. I think the Juno engineers will consider 'finagling' a very low priority compared to making a successful plunge into the atmosphere to protect Europa from encounters with the Juno spacecraft. Our opportunities to get any observations of satellites is limited by our polar orbits, as has been noted already. In fact, our best continuous images of the Galilean satellites may be taking place right now with what we call the Approach Movie. This will be released on July 4.

MOD NOTE: Edited topic title to make it a generic thread for Jovian satellite observations by Juno. Since there aren't likely to be very many, this may suffice for the mission. However, if subtopics are required we'll split them off as needed.

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.
