Astro0, would you try to insert a shadow in my last image?

QUOTE (djellison @ Feb 27 2006, 05:45 AM)  Not far from perfectly circular Rasied rim Similar to many other round-raised-rimed-impactey-type-features. I don't think the thought that it was anything else would have crossed peoples minds. Doug Doug, if you look back about a year or so ago, I believe I was suggesting that Eagle crater may well have been a sinkhole. Ever seen a sinkhole? They're not far from perfectly circular, and they're similar to many other round-impactey-type-features, and if you leave one in a dusty place for a few million years, aeolian deposition will raise an irregular rim around it... That said, I think the odds of Eagle being an impact crater as opposed to a sinkhole are in the range of 80-20. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

I agree that Eagle is *probably* an impact crater, but - apart from the points Doug has raised - I've still to see any evidence. Like... ...shocked and deformed layers in the outcrop. Absence of evidence is not evidence of absence, granted, but there clearly *are* other sorts of holes in the ground around Meridiani, and I'd just like to nail Eagle firmly into the impact camp (or, less likely, otherwise) rather than simply making the obvious asumptions.

I just did a quick search, and it was actually nearly two years ago that I made the comment:
Post If we want to keep talking about Meridiani craters being sinkholes vs. impact craters, maybe we ought to move the discussion over to the Opportunity forum...? -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

A sinkhole idea may be do-able, but given that there are many impact features on Mars I'd be inclined to think "impact". But there is something going on-- look at the many anatolia troughs in this area and at chaotic terrain where much of the subsurface has been removed. Let's look a terrestrial aerial photos in karst and arctic permafrost regions and see if we can find examples.

QUOTE (dilo @ Mar 1 2006, 09:03 AM) Must agree! We want more like this!!!Thanks dilo, SigurRosFan and helvick. It may sound a bit sad, but actually producing these SFX images is my form of relaxation. Spending a few hours exploring Gusev or Meridiani and adding this third-person dimension is enormous fun. I'm glad that others through UMSF can enjoy it as well. I'd like to suggest that we close this thread here (under Spirit), and perhaps re-open it under 'Tech, General, and Imagery'. Now that we are starting to do Oppy pics as well as Spirit, it doesn't seem the appropriate place. It will also give the SFX'ers a chance to talk technique. What do you think?  Astro0 MyMERSFX |

For me too, the (pre)occupation with science in general and Mars in particular, the image processing (including the programming of the tools) is a form of true relaxation and therapy of an intensity which I otherwise only found in outdoor activities like hiking or snowboarding  QUOTE It may sound a bit sad, hey, this is just a beautiful hobby, there is nothing sad about that

Eheh, frankly I wonder nobody else thought to use this image (which was posted by Doug)... I think that "Dr SpRock" could be a good name, or we could use the name of the "stone giant" from Never ending Story (sorry, I do not recall it, but someone posted his name some time ago). -------------------- I always think before posting! - Marco -
