Here is my colorized version of the latest and sharpest LORRI picture of Ultima Thule. Colors from MVIC low resolution picture:

I don't think there will be much higher detail than this to come. Will there?


Well, these are the highest resolution images, but with the raw pixel data, and a lot of processing time,
you can pull out sub-pixel detail, to identify sub-pixel match points.

https://en.wikipedia.org/wiki/Super-resolution_imaging


If you are lucky, the match points differ by an exact multiple of pixels, meaning they're "in register" and you can stack multiple frames to get superresolution images,


https://petapixel.com/2015/02/21/a-practica...with-photoshop/

If the images are off register by fractions of pixels, then you would oversample to generate an image with finer grained pixels, then overlay those images.
The oversampling is similar to an "enhance the image" technology developed by Google.INC using over-sampling and AI facial recognition algorithms.


https://www.extremetech.com/extreme/244105-...-enhances-works

But you'd need Google.INC to train a new ResNet/PixelCNN programmable AI and feed it thousands and thousands of images of craters and moons, to eventually build up a neural net that "sees" geology and impact craters...

Because right now, the Google.INC AI would simply draw a face on Ultima Thule.

I think a lot of us were expecting to see more detail, of course MU69 does not have the topography Pluto does. Also the pictures of Manhattan that were posted by people did really help much to give an accurate expectation. There are no Freeways or Skyscapers.

Raw pictures posted: http://pluto.jhuapl.edu/soc/UltimaThule-Encounter/

I wonder that, maybe however, the NH team is hiding "something special" for the March conference...???

it's just my little hope unsure.gif

Well, there's been no public release yet of the colour version of the MVIC frame from Jan 1st...

I'll quote mcaplinger on the topic of when the MVIC data will be released:

QUOTE (mcaplinger @ Jan 28 2019, 04:17 AM) *
https://pds-smallbodies.astro.umd.edu/data_...AP-01_R0_C0.pdf doesn't describe the schedule for the extended mission but Table 3 says the first delivery of Pluto encounter data took about 9 months from encounter.

To the extent that the spectral responses of the two cameras are different, you could create a crude 2-false-colour image from those frames. You'd need to warp one frame to align them better, though.

I was in that session at LPSC - they are working on shape and stereo but more to do for a final shape model. Then the images can be merged effectively.

Jeff Moore said they are not convinced the small pits are impact craters, and suggest some may be drainage depressions leading into sub-surface voids. Not sure I agree, but a size distribution plot would be a useful thing to help with that problem.
