Default Possibly Once-habitable Ancient Martian Lake Discovered

http://www.sciencedaily.com/releases...0306133930.htm

ScienceDaily (Mar. 6, 2008) — Scientists studying images from The University of Arizona-led High Resolution Imaging Experiment camera on NASA's Mars Reconnaissance Orbiter have discovered never-before-seen impact "megabreccia" and a possibly once-habitable ancient lake on Mars at a place called Holden crater.


I think that every day we are closer to a hipotetical finding of ancient life on mars, what do you think.

Possibly. Just because it seems that it may have once been habitable by our standards does not magically conclude that life arose on Mars, however.

I think every day someone will make wild speculations about life on Mars.

For non oxygen using life, earth in the open air is a very nasty place to be. Heck, for most of the life on the planet, these mountains, these plateaus that reach past the barrier into space, it is lethal. One critters comfy abode is another's Terra Toxica

If life is natural in any liquid water or it can survive being blown of one world and landing on another, there is life on Mars, under the ground. They are probably microbes, but they are most likely there.

That is a big 'if' my friend.

I knew I had read that idea before, I followed that thread quite closely. I don't like how the idea jumps from an unproven to unproven. Besides, so much free water might not be a friendly environment for life forms adapted to the endless sea, like how one can over water a cactus.

That's leaving out the middle part, of many millions of years floating through space.

And we don't actually know that life is "natural in any liquid water".

We've revived dormant life from 250MYA and we've found life deep within the Earth. Granted, the window for life to come from Earth and colonize Mars is ony about a billion years, as liquid water is required for the life to move below the Martian surface before the planet freezes. All you need is one microbe and an entire world is infected.

All you need is one live, reproducing microbe. That can live through the landing and survive in the conditions of the new planet.

Just for curiosity sake, someone go to marsanomolyresearch.com and check out "Hale Crater Evidence" report #084 and report #020 "Water and Plant Evidence" and let us all know what it is you think you are looking at. I have conclude earlier on another thread that the author of the site either: 1. faked thousands of pictures 2. ESA has tampered with the photos 3. Atmospheric conditions produced these anomalies 4. or it is what it appears to be. This is not a challenge to any of you. I just want opinions either way. Jay was kind enough to give me his opinion on the author. A valid contribution to my curiosity indeed. But these pictures need further explanation in my opinion. Anyone up for this??--joe

I'm willing to bet it'll look just like... a two-dimensional image. We can see shapes in clouds, doesn't make them horses or elephants in the sky. We can see things that look like other things, while actually being something totally different. That's why anecdotal opinions from people who are not experts in photo analysis isn't much good as evidence.

The most qualifiers I've ever seen before "lake".

I was examining satellite photos of my parents home in northern Minnesota. They were two dimensional images. Yet I could make out the garage, house, dock, a 12 ft boat etc. I am certainly no expert in photo analysis but what I was looking at really looked like what I had just described. With all due respect, please take a look and just tell me they are angels in the sky or whatever you feel it is. I make no claims, I just want someone to tell me that the Hale Crater evidence for example is not what it appears to be and if you can tell me why, please do so. I don't care that the investigator for this site is a carnival barker down the street. If the pictures are ESA and what we see in them can be duplicated by anyone, including photo experts just tell me what we might be looking at.

Yes, I know, not very scientific huh? I agree by the way. How could that picture be a lake with an island in it? We all know the water would have boiled away millions of years ago. If that is what you are writing about. To me it looks like a lake with an island in it. I don't see how it could be Kai. But it is far more interesting than looking at desert scenes and dried up ocean beds. At the very least it deserves an expert scientific explanation. I am not qualified to make that explanation. To me it just looks like a lake with an island and that just doesn't fly--joe

What I meant was that the title had four adjectives describing "lake". I was trying to be funny.
