as soon as they get the 'mass extinction' tied to a 'global warming' scenario.

NASA also found evidence of water in other places in the solar system. If memory does not fail, Pluto and one of Jupiter's moon?
The other question is, can water simply disappear or does it move somewhere else? For example, is water on Earth disappearing or relocating to different regions of the planet from where it once was? If so, and Mars really had water, where is it? |

The larger question is why did Mars dry out? And when?

If so, and Mars really had water, where is it? I was told by a physics professor that it basically boiled off into space. http://www.space.com/30746-mars-missing-atmosphere-lost-in-space.html So, if the thick atmosphere didn't become locked in carbonate deposits, what happened to it? One possibility is that it might have been lost to space from the top of the atmosphere — a phenomenon that NASA's Curiosity rover has found evidence of in the past. |

Just because there is water, doesn't mean it is amenable to life.

Seems that Mars had oceans for a long time, maybe 2 billion years from what I've seen. Along with a thick atmosphere and a magnetic field...seems like a recipe for at least simple life if not higher forms of life. All those sedimentary rocks in those pictures from Mars, who knows...maybe they will see something. |

Multiple reasons for Mars drying out.
1. It has had it's atmosphere stripped by solar winds, with no real magnetic field it does not have the protection from solar winds like the Earth does. 2. The atmosphere thinned, and the drop in pressure cause the liquid water to boil off. Mars had liquid water early in it's life, that is a proven fact. It does not have a large iron/nickel core to form a protective magnetic field. Take note that the closer our planets are to the Sun the denser they are. Mercury is has an enormous metallic core compared the planet size and as you move away from the Sun those cores become smaller, until you get to the gas giants which are a different construct but have huge magnetic fields due to metallic hydrogen cores. I did not stay in a HIE last night. I sat in planetary astronomy classes. |

I did not stay in a HIE last night. I sat in planetary astronomy classes. The water loss and the planet's construction makes sense. However, if the planet was built like that it would had never had an atmosphere, water, etc. So, it means one day it had the conditions necessary to retain atmosphere and water. So, what happened that changed that? Planet changed or some solar event changed that? Could this event also had jumpstarted some transformation on Earth, which might had been different than it's today? |

Water has been found throughout the solar system. We can infer that Mars got its water just like the other planets and moons. Theories abound but right now it is assumed the water was a major constituent of the nebula that formed the Sun and solar system. In a nut, all the solar system's objects started with water and only a few held on to it.

If so, and Mars really had water, where is it? Mars has little or no magnetic field like the earth has that protects us from the Solar Winds. The Solar Winds have stripped Mars of most of it's atmosphere(including water vapor). The same would happen here if the earths core cooled and the magnetic field ceased to exist. In short the Sun stripped Mars of it's water. |

See my previous post. Its is believed that Mars did once have a molten core and therefore a magnetic field to protect it's atmosphere. |

All those sedimentary rocks in those pictures from Mars, who knows...maybe they will see something. Yeah, but I think we've always had a rather closed-minded approach as to what can sustain life. We have a pretty good idea of what's required for life on Earth, but even on this planet there's tons of life around volcanic vents where superheated water packed with toxic elements - and not just microbial life. That required a good rethinking when it was discovered. There are microbes that feast on sulphur with no oxygen present: 
And silicon cycle life is plausible. Not to mention we've observed that water bears can live in insanely extreme environments: For example, they can withstand temperatures from just above absolute zero to well above the boiling point of water (100 °C), pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. They can go without food or water for more than 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce. I doubt we'll see anything on Mars that we would recognize as a creature similar to the ones on earth, but I believe we'll eventually find things that make us question the very definition of life, what constitutes it, and what environments it needs. |

Like this image, that was found within the first week or two of operation? And many other unusual small rocka
How long before they find a patch or algae? Or at least acknowledge finding some. |

That looks like a coral don't it... Humans have an amazing ability to apply our mental image to things if they are somewhat close. Dog shaped clouds, deities in toast etc. Just because it kinda looks like coral does not mean it is coral. People saw a face on Mars after the flyby pics from the 70s, it was just lousy pics and the MRO proved that years ago. Other people have seen rabbit shaped rocks, and even a lady in a flowing dress in the formations. Those are not real either. Let the pros sift through the data, and pictures. They will do their best to discover what is really there. You can be guaranteed if they find fossils NASA and JPL will share it with the world. That is way they will get funded for a human trip to Mars and will reignite the world's support for manned spaceflight. Elon Musk is going to do it on his own if the big dogs don't get busy. Well, Musk is really the Big Dog these days. |

Well, Musk is really the Big Dog these days. I'm not saying that is what it is, I'm saying that is what it resembles. Since we are dealing with a b&w pic, it's even harder to judge.... But anyway...when this ??? finally gets answered, I think that we are going to find that simple life is common in the universe....higher lifeforms a lower percentage but still common given the size of the universe... Basing this on the fact that we are finding that every star has a planetary system and the fact that we are finding biological compounds and water everywhere we look even in our own solar system. I'm even going to go out on a limb and say that life has a basic recipe and format common to its existence wherever it is.... |

I absolutely feel that we will find simple life beyond our Earth right here in our solar system. Just that "stuff" in the pic is not coral. Interesting formation but not coral.

It is far more likely to die of radiation exposure long before it finds a visible fossil.
