Is there any place on Mars that plant life, be it lichens or whatever, could survive now?
There are ‘Gardens of Eden’s’ on Mars. Places where the climate can, at times, be almost Earthlike. Hellas is one of them, and probably the largest. There are times when pressure gets to where liquid water exists, and temperatures get above freezing.
It would be interesting to try and get something to grow there.
Weirdly beautiful. Would be curious as to an explanation of *how* such landscape forms.
--Cindyhttp://www.msss.com/moc_gallery/r03_r09 … .html]That weird image, (thanks REB for finding it) is of some West Hellas Planitia rugged terrain.
To me, it smacks of water-transported sediments. It really looks a bit like exhumed remnants of the type of meandering and overlapping swirls you get in marshes and estuaries as small streams drop their sediment and keep building their banks higher until they spill over into lower ground starting a new swirl pattern to occlude older ones. Either that or built-up travertine pool rim deposits. If sedimentary, it looks like the white swirly parts might be composed of sediments much like the light colored material at Opportunity's site. I wonder if we might find it too riddled with blueberries.
One weird thing about it is that the areas below the swirly parts looks as if it overlain by darker material, which appears to be riddled with many sand-fileld craters. If they are craters, which they appear to be, then its kind of odd because the craters appear to be much more abundant in this small area that has sand atop it, whereas the swirly parts have very few craters with the very noticeable exception being that crater smack-dab in the middle of the stream near the right of the image, the stream apparently seems to push around the crater hole bulging around it on either side as if to compensate. go figure...
???
That is the strangest, weirdest landscape I have seen on Mars, and probably in the Solar System.
The area the picture shows is close to the lowest point on Mars. I do not know the Long/Lat of the lowest point. I might have to dig out a National Geographic map of Mars that shows the lowest point.

The dark features still look Liquid to me. I see islands, a coastline, and even hints of rivers. Of course, I might be seeing things.
Thanks Cindy. I probably will not have the time to dig through MOC pictures. I have started a new project that is taking up most of my time.
http://www.msss.com/moc_gallery/r03_r09 … l]Probably the weirdest terrain I have see on Mars.
This is in Hellas Basin, where temperature and pressure sometimes get to where liquid water will not boil away. When I first saw this terrain, my first thoughts where of taffy in a taffy machine. I suspect the ground here is some kind of gooey mud mixture that thaws and freezes over and over.
http://www.msss.com/moc_gallery/r10_r15 … .html]More here. Something is keeping a young surface in Hellas.
http://www.msss.com/moc_gallery/r10_r15 … .html]This MOC picture is taken near the low end of Hellas. Notice the muddy appearence of the area, and what looks like a flooded area near the center of the picture.
This could be a slushy type ground simular in texture to what they are expecting on Titan.
I would love to see a MER here.
http://www.nfinity.com/~exile/marsweather.htm]Good information on the Hellas Basin
From the webpage;
"Because of its latitude and great depth, it seems likely that there is an abundance of water ice under the surface in the Hellas Basin. Mossbaur spectra, which can detect the presence of hydrogen, suggest that, except for the poles, this may be one of the "wettest" places on the planet. It may possibly be the last place where liquid water ever existed on the surface of Mars. In mid summer, it is one of the "garden spots" of the whole planet, with atmospheric pressure of over 10 millibars, more than twice what it is at the mean planetary horizon. Since the vapor pressure of water is lower than 10 millibars if the temperature is less than 60 deg. F (16 deg. C)(4), this may be one of the few places on the planet where any water on the surface will not immediately boil away. The days are long and relatively warm, and the nights are fairly mild, considering how far north the Hellas Basin is located."
Cindy, nice topic.http://www.msss.com/moc_gallery/r10_r15/images/R10/R1005415.html]This Noachis pit crater has been an interest of mine for a couple of years now. Like the crater in you article, I think this was has been buried and is now being exposed. I think it has a high content of frozen water.
I thought it was getting a power boost from the angle of the slope it is on, which causes more of a right angle between the solar cells and the Sun.

Nice meanders too. Looks like recent water carved them.
http://www.msss.com/moc_gallery/r10_r15 … pg]Another Inca City picture. Like the picture I posted above, this one has more of what I call Mars spiders. They are near the bottom of the picture. I am not sure what these features are, but I suspect they have something to do with the freeze/thaw cycle. Crystallized carbon dioxide?
http://www.msss.com/moc_gallery/r10_r15 … 73.jpg]Not to be out done, the South Pole area of Mars has its own interesting features.
http://www.msss.com/moc_gallery/r10_r15 … 7.jpg]Here is one of Inca City near the South Pole
Cindy, if you like dunes, the north pole of Mars has interesting Dunes. I thought you would like http://www.msss.com/moc_gallery/r10_r15 … 3.jpg]this one, http://www.msss.com/moc_gallery/r10_r15 … 5.jpg]this one, http://www.msss.com/moc_gallery/r10_r15 … 1.jpg]this one, and http://www.msss.com/moc_gallery/r10_r15 … 9.jpg]this one.
Mars is a strange place. http://www.msss.com/moc_gallery/r10_r15 … 3.jpg]This landscape looks like very dry and cracked skin. Very interesting. I bet water once covered this area.
Cool picture, Cindy! Pokka-dots.
Mars does have some strange features.
http://www.msss.com/moc_gallery/r10_r15 … 5.jpg]Here is another area with what looks like mud cracks.
This area would have been covered with the Northern Ocean. Notice how the crater is a more recent event then the cracks, having obliterated those around it. It looks like there may still be water frozen under the surface, as the impactor looks like it melted the ice.
http://www.msss.com/moc_gallery/r10_r15 … 3.jpg]This Picture has a nice ice or debris tongue at the bottom of the crater. Notice what I call mollusk trails (for lack of anything better to call them. They look like the trails mollusk make in the sand) near the center of the crater- off the north side of the central peak. What are those meandering trails?
Oh, I forgot this one. I found where the Martians are hanging out Check out the dark spot in http://www.msss.com/moc_gallery/r10_r15 … 9.jpg]this picture.
They are probably house size bolder, but besides their contrast to the surrounding terrain, I find their distribution interesting. Reminds me of vegetation growth- if only it was that.
Yardangs I always loved that name.
I have been digging aroung the Utopia Planitia today.
I found an interesting crater in http://www.msss.com/moc_gallery/r10_r15 … 559.jpg]My Webpage this picture. I am guessing that this is a shoreline of the late Northern Ocean. As the water dried, the ground shrunk towards the center of the crater, creating the circular cracks.
http://www.msss.com/moc_gallery/r10_r15 … 5.jpg]This picture has some wierd looking features in it towards the bottom.
It doesn't looks teal as it reminds me of some of those Venus radar pictures.
Opportunitys]http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040615a/11-SM-01-Endurance-A160R1_br2.jpg]Opportunity's locatgion in this picture would be torwards the left. This picture was taken somewhere above burns cliff.
http://marsrovers.jpl.nasa.gov/gallery/ … 2.jpg]This one was taken on the other side of the crater. Notice how steep it looks under Burns Cliff. When looking at Opportunity's current pictures, http://marsrovers.jpl.nasa.gov/gallery/ … .HTML]like this one, it is hard to tell what the angle of the slope is.
http://www.msss.com/moc_gallery/r10_r15 … jpg]Headin northeast of Opportunity is the Cassini Basin
I like that second large crater (About 1/3 down the page). Very artistic.
http://www.msss.com/moc_gallery/r10_r15 … 1.jpg]LOne More. This one is in the same crater as the pictue in the above post.
Talking about dark area's looking like water. Look at these. There are features here that look like shorelines, deep water, shallow water and islands. This is one reason I don't want to jump to conclusions with those Titan pictures where I see what looks like shorelines and river channels.
http://www.msss.com/moc_gallery/r10_r15 … 0.jpg]More layering West of Oppotunity.
This one could be considered art.
http://www.msss.com/moc_gallery/r10_r15 … 19.jpg]Not far from that previous pictue is this nice one.
Check out the layering at the bottom of the picture.
BTW, these last two pictures are in an area not very far to the west from Opportunity.
