Damn, no sign of Beagle 2, I guess we'll never know now.

The pictures of Isidis are in my download list, I'm going to check them very carefully.

Yep, I think the gullies images are the best of this release.

Check out "Tongue-Shaped Flow Feature in Hellas Planitia" (PSP 002320 1415). Obviously, the Rolling Stones are promoting their upcoming tour of Mars.

Nice to see the statistics (file and pixel size) are back, and have been retrofitted to the previous releases as well.

I've started a new thread just for B2-in-HiRISE searches...

Check out "Tongue-Shaped Flow Feature in Hellas Planitia" (PSP 002320 1415). That's definitely my favourite from this set. It looks exactly as if a whole hillside just turned to sludge on a warm day! Does anyone know the context for this? Elevation? Flow gradient? |

I was doing some stuff to the images, and came across Vent at the Summit of Arsia Mons Volcano, image PSP_002157_1715. If you look at the right parts of the image in high resolution, you will see that it is a very textured surface, something that I haven't seen previously. I went through the stack of released images, and found that this one had already been released, but I think there might be a bit more story to it. I don't think I've ever seen an image that had such a regular pattern, certainly not through craters and mountains alike, but you only see it in high resolution.

Sounds interesting. Could you post a hi-res crop, with scale bar and context if possible?

This image is about 600x350 m or so, near the right edge. A quick sweep shows that this is visible everywhere, not just in this section of the image. For context, well, you could use the browse image found at the HiROC website, that shows what the whole scene looks like, if you want something between, let me know. Oh, another feature of note is the largest crater, it is about 70m across by 74 high. This image is full resolution as well. |

Thanks tuvas, that is an amazing overall texture. They look a bit like the star dunes inside Victoria only less regular. Assuming they are indeed dunes (and hoping I correctly understood some earlier posts on that subject) I think this pattern implies two things about the location - very abundant dune forming material and many different wind directions with no clear prevailing wind.

When tuvas first showed me this image, it was backwards, and to me it looked like the surface of a football (an American football...). OF course, now that I see it in the correct orientation, I concur with ngunn, looks like star dunes to me.

Well, the region is the top of a volcano, among the dustiest areas on Mars. The lack of prevailing wind is interesting, but I could well believe it. Still, this did catch my attention, it certainly is very stunning. |
