Ancient Mars Texture! Warning Large Images Inside!

Post #1by Don. Edwards » 13.02.2006, 03:35

Now that I have a working high level texture of Mars I thought it was time to resurrect the long dead 3.5 Billion year Mars texture that I had started a while back. So far I have been able to make some pretty good progress. Some of the layers need some work but I don't its anything to bad. I am using data from some pretty old textures to make this so bare with me here. The above image is of a very quick and dirty down sample of the 16k to 8k for quick processing and image taking. The main 16k version is every bit as detailed as the Mars texture, except of course color changes and the water layer being added. Oh and some more Earth like clouds. Here are a few more shots of the texture from all sides.

I will keep everyone posted a things move along. I don't have any kind of a time for release set as I just started working on this last night. After this is finished there is one more Mars texture I have been meaning to update I have made in the past, I think its time to update it as well,
That?€™s it for now, as always comments and questions are always welcome.

Ah, never say never!!
Past texture releases, Hmm let me think about it

Thanks for your understanding.

Interesting,but still there wasn??t any prove that Mars had this amount of water.The last results said that Mars had been cold and dry for billions of years!!So this texture is entirely fictious.Mars never had large bodies of water,maybe only small lakes...

The amount of water that Mars had in the past changes according to new discoveries every week, Danielj. Three weeks ago there was a report by a team who upheld the northern ocean hypothesis. last week, another team stated that not only was there no ocean, but *any* surface water was unlikely. I suppose you can go with whomever you wish to believe, at this point. For myself, looking at the various data that have been returned in the past couple of years, I lean towards I high water content in the past.

<B>Don</B>, this is a texture that I've been waiting for for some time. I'm <I>ecstatic</I> that you've decided to ressurect it!! And I certainly can't wait until it is released!!

My only question is, would there be as much cratering on the planet as we see now? Do we have any definitive dates for some of the larger basins, such as Hellas?

Hey Dollan,
From a few things I have read, Hellas and Argyre Planitia formed at roughly the same time, and both a vary long time ago, at least timed to the start of Tharsis and Vallis Marineris. Of course there would be fewer impacts and craters, but figuring out which ones to leave out and how to do it that?€™s the problem. I guess I could take creative charge and remove what seem to be the newest impacts and so on. It will be allot o work, but i might be willing to try.

And on the issue of ancient oceans on Mars, I personally am in the Northern Ocean group, I think there is ample evidence right on the surface of there once being a great bodies of water that covered most of the planets northern hemisphere. Some scientists are just so locked into there own ideas of Mars and how it is now that they can't take the leap of imagination to see it as it may once have been. Even if the evidence is slapping them in the face, they refuse to look at it. Hey being intelligent doesn't mean you are smart or vary observant.

Don, just discovered this post. Are you resurrecting your terraformed Mars textures and updating them? I aks because just today, my students began their journey into the future of Mars in Activity 5 - The Terraforming of Mars. If you plan to update the textures, that would be good news (although your original ones are spectacular in their own right).

:D

Intresting image.

I have been intrested in looking at different ideas of ancient mars. Here is something I have done (maybe intresting for you):

http://magnus.infidyne.com/mars/water/

I have oceans on mars in many different heights/volumes (128 different images), eac 11k x 5k pixels. Plus 2 HDTV movies (fast + slow) that shows each of these 128 images in order.

Will try to do better versions in the future with correct "true-color" texture (now its just altitude colors), and better ocean colors, etc. I would love to do it in much larger size too for more details.

We discuss it here on UMSF:

While it's true there is some inertia in science, I don't think scientists are ignoring evidence. In fact, I think there are far more scientists who want to declare that there is liquid water and life when there is no evidence for it than there are ones who supposedly 'refuse to look at the evidence' and say that it's just not there.

The problem is that the evidence is highly ambiguous: features that could be explained by water could also be explained by ice (eg the 'splat marks' in the northern hemisphere could be caused by impactors hitting either ice *or* muddy seafloor or just plain waterlogged soil). Certainly there are channels carved by liquid on Mars, but they could have been carved during brief catastrophic events rather than over millions of years as a river.

Personally, I'm in the 'Northern Ice Sheet' camp, unless better evidence supporting liquid water comes along.

I believe that at the present the mud water color to be the right one and should avoid an hasty inclination toward the terraforming ideal.

And , also, the sky should be dark blue because the young Mars atmosphere had a pressure of approx. 0.07 bar so that atmosphere should not scatter too much light but percipation was preventing the micro red iron oxide particles from accumulating in the atmosphere.

m1omg,

I only have the texture made in its earliest stages. So its far from ready for mass consumption. As soon as Terraformed MArs is finished, this is the next in line. I have alot of craters to remove. :wink:
