I know the first close Io flyby is still a couple of months away but I'm going to go ahead and start up the topic now with a few preview images that the global map from PJ55 into the pixel scale, lighting conditions, and orientation of the highest resolution images that JunoCam would take (illuminated by the sun, there's always a chance for Jupiter-shine images), based on the current reference spk and c-kernel:
This also assumes an image cadence of 1 every other rotation (so 1 per minute). info about the encounter: CODE Perijove Date (UTC) SC Altitude (Io, km) SC Latitude (Io IAU, deg) SC W Longitude (Io IAU, deg) Vinf (Io, km/s) Phase Angle Magnetic Latitude of Io (Jupiter System III, deg) E Longitude of Io (Jupiter System III, deg) True Anomaly of Io (deg) Separation Angle

Hello UMSF members,
I follow everyday all your exchanges about lunar and planetary missions. I'm one of the co-authors of the "Virtual Moon Atlas" (VMA) and "Virtual Planets Atlas" (VPA) freewares. https://ap-i.net/avl/en/start https://ap-i.net/avp/en/start Our goal is to provide for general public and scientists, easy to use basic tools for improving lunar and planetary knowledge. As you will see if you download and try it, VPA presents telluric planets and Galileo satellites real time maps. For that, we use with permission equirectangular "textures" in the 2:1 ratio buit from various planets maps found on the Internet and publically available. I would like to add in VPA Juno's maps of the Galileo satellites since presently, there are only Voyagers and Galileo maps used in the freeware. Using the VPA "double window" functionnality, it will certainly be useful to look for planetary surface evolutions between these various missions for VPA users. Does anyone could help us and provide such best resolution equirectangular Juno maps for Io (Sure !) but also for Europa and Ganymede that can be used in VPA with permission and thanks ? (Natural or enhanced colors / B&W / 2:1 ratio / jpg format / 4000x2000 pixels minimum or more) Thank you in advance for your support to our action if you agree. Ch. Legrand PS : Sorry for my rather poor english |
