Data of Juno's Perijove-10 are going to be downlinked.
Here is a tiny 6000-fold time-lapsed simulation from 2017-12-16T16:30:00.000 to 2017-12-16T20:00:00.000: It shows, that during approach, Jupiter's night side has come into JunoCam's field of view, first. Then there have been some interesting new perspectives, before Jupiter's south polar region has been in JunoCam's view during departure. The simulation is based on preliminary, and on some reconstructed SPICE data. Timing of actual image data differ from the stills of the above tiny simulation. |

Here are my versions of image PJ10_028. I recently made minor improvements to my processing. The biggest difference is that now I no longer 'lose' the fuzzy and bluish horizon at the limb in the hi-res images as as result of the processing (the limb isn't sharply defined in these images as in my earlier images). First three approximately true color/contrast versions:
Notice the bluish horizon at the limb, especially in the central image. This is Jupiter's blue sky. And versions with enhanced colors, contrast and sharpness: Juno was only 4420 km above Jupiter's clouds. This is especially obvious in the central image which has a field of view of 70 degrees. The image below shows Jupiter's blue sky at the limb; this is an approximately true color/contrast image. This image has a field of view of 20 degrees. This corresponds to an enlargement by a factor of ~3 compared to the original framelets. And finally a subset of the relevant metadata: IMAGE_TIME = 2017-12-16T17:59:33.468 MISSION_PHASE_NAME = PERIJOVE 10 PRODUCT_ID = JNCE_2017350_10C00028_V01 SPACECRAFT_ALTITUDE = 4420.2 SPACECRAFT_NAME = JUNO SUB_SPACECRAFT_LATITUDE = 5.7721 SUB_SPACECRAFT_LONGITUDE = 297.5258 TITLE = North Equatorial Belt, southern edge Resolution at nadir: ~3.0 km/pixel |
