It's time to open a perijove-4 thread.
Voting is open for another two days. So, don't hesitate too long. Besides the discussion and the POIs on the mission page, you might consider John Roger's detailed discussion of several interesting features. If everything goes well, all instruments will be switched on. |

For the simulation you require more than just the apo- and perijoves. The same NAIF/SPICE directory contains also the file spk_ref_160829_190912_161027.bsp with more detailed information. Together with other kernel files you can simulate most of Juno's behaviour. I'm using the trajectories to create reprojected JunoCam products like these intermediate images (portions mirrored).
That said, the perijove dates and times should be sufficiently accurate to compare them with predicted shadows of the moons. |

For the simulation you require more than just the apo- and perijoves. Well, there are two steps: the first is to figure out if there are any eclipses near a perijove pass, and the second is to determine if the shadow would be visible from Juno. For step 1 you don't need to know where Juno is exactly. Keep in mind that later in the mission Jupiter isn't even in the Junocam FOV for a lot of the time as the orbit plane migrates away from the terminator, so that's another constraint. -------------------- Disclaimer: This post is based on public information only.
