Mike, since this is image number 01, I assume there isn't a higher TDI image of the night side. No, we didn't think that would be workable within all of the other constraints. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Europa images on missionjuno. That was way faster than I expected, wow There was enough Jupiter-shine to bring the signal from night side up a little bit over noise levels. This brings a tear of joy to my eye, amazing work, Brian! The PSF on that reminded me of the good ol'e days of Cassini which is high praise for JunoCam. Superb work by all involved, it was a long time coming and it was executed flawlessly as far as I can I gather. -------------------- |

Wow! For an Io loyalist, you sure can produce a heck of an Europa image product

I have to make sure my pipeline is ready for next year. and it is.
I may be having an issue with the ice shell not staying in place... -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Great images here, and it looks like real detail could be pulled out of the night side in that first image. Maybe with the HORUS software being used now with LROC images of shaded areas.

Does anyone suspect any surface changes?

Fantastic relief details near the terminator!
There seem to be two large but shallow north-south trending but broad 'troughs' roughly midway through the illuminated half of the disk. Are these real, or just imaging artifacts? P |

Does anyone suspect any surface changes? It's going to be really hard to find anything like because the existing Voyager/Galileo coverage is mostly at much different sun angles. I'm sure people will be looking hard in the weeks to come, though. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

They're real- Paul Schenk has called them "crop circles", and they tend to follow small (not great) circles. Very interesting and odd features. They're visible on the Galileo mosaic.
Congratulations to the Juno team! John |

There seem to be two large but shallow north-south trending but broad 'troughs'... Are these real, or just imaging artifacts? Those are real. See https://astrogeology.usgs.gov/search/map/Eu...bal_mosaic_500m One of them might be Eightercua Fossa? -------------------- Disclaimer: This post is based on public information only.

ehhh, there might some hints at Jupiter shine, but ehhh, it isn't much:
One of them might be Eightercua Fossa? Yeah, Eightercua. I spent way too long last week learning how to pronounce that... -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
