Nice work, Ted.

It always amazes me how accurate a descriptor "cantaloupe terrain" is for Triton. I wonder if Triton is orange on the inside.

New mission proposal: Deep Impact, Triton. The mission will release a projectile equipped with a nuclear device powerful enough to break through the moon's rind, allowing the flyby craft to study the ripeness of the melon.

By the way, here is a full resolution version of the last of the series.

No, no, no, Ted -- what we really need is Deep Rap - Triton, in which a huge *knuckle* is sent to Neptune's largest moon and used to rap on the rind. Extremely sensitive microphones aboard the flyby craft will then listen for the "exact right thunking sound" to determine the ripeness of the interior...

Not on the inside, but on the outside - at least partly.
Have a closer look at the left one of Ted's Triton pics. There's an orange area visible at the left upper limb.
Some far distance images show more of this orange tint, like this one:


Btw., marvelous work Ted...

The color seems to show up under low solar angles, although it is much less pronounced than in that image - Triton is rather whitish, really. It has all sorts of hues, but they are much more muted. Color exaggeration can be a good thing, but I have avoided it because the coverage I have here is so inconsistent that I am having enough trouble making the images seem remotely similar as it is.

I have improved my Proteus set. I have always thought there were features in the "Bad Tooth" image. After reprocessing these images, there is clear correlation between them. The highest resolution image has a resolution of 1.35 km/pixel. For context, that is somewhat better than the best pictures of Ariel (2.4 km/pixel). However, it was so severely underexposed that it is usually blurred to hide the effects of underexposure, making it appear to be an enlarged but distant image.

That's AMAZING Ted - I am ASTONISHED at the level of detail you've pulled out of the raws. What type of processing are you using here????

[tedstryk]

I used Photoshop. After calibrating the images, I compiled the pixels of some of the empty space from the images in the vertical direction (minus rows that contained moire) and subtracted this from the image. I used several noise reduction methods so as to minimize the loss of detail. I also used a high pass filter to bring out detail, which I merged with other versions of the images so as to bring back the low frequency features. Here is my complete Proteus set (the image in the upper left corner is Larissa, and next to it is a crescent Nereid, but the rest are Proteus).

Unbelievable, Ted. That's the first time I've ever seen a resolved image of Nereid...always wondered what it looked like. Thank you so much for this gift!!!

Now I can visualize how the terrain around the Outsider's base looked when Speaker-To-Animals tried to steal the Long Shot from the Puppeteers...

That odd texture on Proteus has got me scratching my head. It's too distinct to be a processing artifact. Does anyone know if any other solar system body exhibits half-swirls and brush-stroke features like that?

[nprev]

Yeah, I noticed that too, Dan. (I was also struck by the apparent low cratering rate, but it seems logical that the inner Solar System was/is much more prone to this; Neptune's orbit may sweep out a lot more volume of space, but there's also probably been a lot less debris out there since well before the LHB.) However, I do recall seeing things like the "brush strokes" in other enhanced imagery of other objects, so my money's on image processing artifacts.
