QUOTE (n1ckdrake @ Dec 25 2007, 09:28 AM)  Slope streaks in Arabia Terra... Wow. Cool image! I wonder what's going on with the very linear terminus to the flow in the upper left corner? Even though I designed a large part of CTX, I haven't looked at 1% of the data from it. From these images, it's doing everything I hoped it would. Thanks for finding them! Merry Christmas everybody! -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

 ...all I can think of is some sort of deep fracture, which drained them rather rapidly.And actually, this begs a question: Why don't we see diffusion features at the end of these things, like deltas? Does the putative water evaporate and/or freeze so quickly that they never get to form? The abrupt terminations are odd in themselves... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE (nprev @ Dec 25 2007, 11:02 AM) Does the putative water evaporate and/or freeze so quickly that they never get to form? I'd have characterized these as dry slope streaks, no water involved. But that terminus seems weird. Only thing I could think of is some topography below the limit of resolution (some kind of a ridge or dike maybe.) -------------------- Disclaimer: This post is based on public information only.

I'm with Mike, here, Nick. These look a lot like dust slope streaks, not like the putative water-carved gullies seen elsewhere. You see these slope streaks all over on Mars, in places where liquid water could not possibly exist (i.e., high on the slopes of the Tharsis volcanoes) and they don't seem to share the V-cut morphologies of the gullies.

Okay, I'm with you guys now; been thinking in terms of the wet model. This feature seems to provide considerable evidence for the dry model.

Here's a hand colorized version of the Rabe Crater picture (unfortunately I have no time left for framing and caption this time ...)

 Every time I see one of your images Nirgal I feel like Luke watching Yoda lift that X-Wing out of the swamp... Humbled...

unnecessary quoting removed
Wow Nirgal, that picture is amazing! The amount of detail you applied is mind-blowing! Thanks for posting this awe-inspiring picture.

QUOTE (hendric @ Jan 10 2008, 03:51 PM) n1ckdrake, What are you using to calibrate and uncompress the raw pictures? Hello hendric. I currently use ImageJ or NASAView to access the raw data. For calibrating images I use Photoshop CS2. And I find Irfanview to be extremely useful as well. |

n1ckdrake, I think that if you
a. change the caption of your latest crater image, b. reduce the resolution, and c. post it in the Paolo's Plunge thread at the Opportunity forum you would have half the forum scratching their heads trying to explain what they see in this "weird RAT hole" Thanks for these gorgeous crater images you provide us. |
