@Landru79 my fav part, around 40 seconds in, I had never seen that you could get a 3D effect on Ahuna Mons!

I took the liberty of cutting that part and slowing it down (original in the replied post)

More intrigue on the presence of water ice on #DwarfPlanetCeres , this paper looks at permanent shadowed regions in northern latitudes using different ways to model the topography. Quite interesting that these regions will still see sunlight in relative short timespans due to 15-20 deg changes in Ceres' obliquity.

Let me finish this #LPSC2024 thread with a #DwarfPlanetCeres paper, covering features I always found amusing in #DawnMission photos. Attached is one of my favs, in Kupalo crater (right "besides" Juling) https://photojournal.jpl.nasa.gov/jpeg/PIA20944.jpg

@nasapics_bot yet another throwback to the golden days of #DawnMission at #DwarfPlanetCeres and all those wacky craters and rims

I took the liberty of stretching and distorting the original to cover more of the frame.
