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

Has the camera performance actually improved since PJ56? It looks like it. Yes, definitely a very large improvement since PJ56. The image quality is now probably comparable to PJ55. This is a preliminary version of image PJ57_22: North is up. The brightness of the nightside has been increased to show details there. |
