Celestia Forums

Looking in the CONAE webpage(Argentinian Space Agency) I found some pictures taken by one of our(I am Argentinian) satelites. The one that most impressed me is this one:


Here you see it in a small size version. The original is a *.bmp, 2007x2916 pixels, 16.7 MB
I think it would look perfect on Celestia. In the big picture you can also see some "natural craters"(they look like craters but they were made by erosion). There are two elliptical and one with a shape of a long heart.
Does anybody want to make a VT rom the picture? I want to do it myself, but I dont really know how to. I recived some tips from some people(like Guillermo) but I still dont know how to do it...

ElPelado,
Are you sure they are not real craters? Or should I say Calderas. There are some volcanic areas in the Dead Sea region. If you follow from the Sea of Galilee in the upper portion on the picture and follow it down to the Dead Sea and continue following it down to the Red Sea you are looking at a branch of he Red Sea Rift system. Very tectonically active and volcanically active as well. If you know were to look you can find volcanoes all over in this region. If you load a 16k Earth texture or the 32k VT texture and look several hundred miles east of the Sea of Galilee you will see a dark brown patch surrounded by a littler brown larger area. The dark brown patch is a volcano and the lighter browns are its lava flows. Of course this can be seen allot better with the 21600x21600 BlueMarble images.
Africa has two of the biggest volcanic calderas visible from space and they can even be seem in a smaller texture as far down as an 8k I believe.
There is this one smack in the middle of the Sahara Desert with other volcanoes all around it.


Then there is the most famous one that had been talked about in animal documentaries for over twenty years. I always wondered were this caldera was and until I got the large textures to work with I found it. If you look in the picture you can plainly see Mt. Kilimanjaro on the right side in the picture and the caldera nature preserve dead to the west.


Just trying to point out that what we see isn’t always what it is or it is and we just are not seeing it right.

Very interesteing info... but I was right about what I said: its not that I think that they are craters, I KNOW IT. Someone who was on a trip there told me about that place. The 3 craters are south from the dead sea. One of these days I'll take the big picture and put here only the part in where you can see the craters.
Believe me, those are craters and not volcanoes neither calderas, just wholes in the ground made by winds and rains(I am not sure about this because it a dessert region, so there are not so many rains, but....) and looooot of time

Here you have the section with the three craters. This image is smaller than the big one that I have, I just cut that part and rezised to put it here.
About the names, I dont know if that transaltion is good...

May be you will see, as I do, the craters like mountains, but its just a shadows problem...

ElPelado,
Ahhh,
I see what you mean. Yes, these are definitely not craters. These are depressions by either erosion or ground seduction from tectonic movement or possibly they are old sink-holes. Only one of them really looks like a crater.

I am not sure, but I think that in the past, there were three mountains with a hard kind of rock in the outside and something less hard(like some kind of sand) in the inside. When the erosion started, the hard part begin to dissapear. When all the hard rock dissapeared, teh sand was easily thrown away by the winds. Thats why you see a whole now: the rock you see there is the hard rock.
