Of course that water might be CO2 ridden. The predominant source of water on Mars is its so called "ice cap" up top of Mars. This is a sheet of CO2 (s) (aka dry ice) covering a sheet of frozen water. Now according to a friend of mine, the pressure build underneath this CO2 layer and it eventually explodes like a volcano-like...idk...because the pressure ...[text shortened]... to be exposed to the air. Then, some of that water could melt and therefore form liquid water.
Originally posted by agrysonWell the camera onboard should show something if it sublimates. It sure will show something if it turns out to be just fresh ice also when the digger scraps into it. Even if it's ice that would be a tremendous discovery don't you think?
the other possibility is that disturbing the supersaturated atmosphere above pool would force it to freeze instantly or to sublime instantly, so even if it IS liquid water, disturbing the pool could still lead to a non-result. Or in the case of instant sublimation, a cool disappearing act!
Originally posted by agrysonYep. What I wonder is, if it is ice, why doesn't it sublimate and dissapear, not much atmosphere, like earth at 100,000 feet.
They'd have to have the equipment on board the rover to differentiate between water ice and CO2 ice (dry ice). and from the article it seems that the camera can't see where it puts the drill. they refer to drilling it, 'then' seeing if it had an effect. I'm certain something will happen, but if it becomes 'inconclusive' I just wouldn't see it as definite pro ...[text shortened]... already have evidence of high levels of groundwater in some form all over the planet.
Originally posted by FabianFnasBut what do you think the likelihood is of finding the same sort or type of DNA that humans have on Mars (or any life for that matter) (extremophiles excluded)? I realize that it might have been habitable at one time, but at what time? It would have had to have been a long time ago, and if humans started on Mars, then why does the current evolutionary scheme have them starting on Earth? that means all of evolutionary ideas ever thought will have to be realigned. Plus, the evolutionary timeline states that humans did not evolve that fast, fast enough to make a habitat on mars and send people to Earth. If any evolutionary concepts are correct, it is the fact that at least both planets would have had to support life at one time, but mars could not support it long enough to stay habitable.
I would really like they found real and living life on Mars! The result would turn religion and philosophy upside down!
If Martian life were based on DNA, the same as ours, then probability is high that Earthly and Martial life has common ancestors. From where? From neither Mars nor Earth? Or is spontaneously travel between the two planets. In this cas ...[text shortened]... iny speck of life at our next door planet changes our view on life and its evolution completely!
Originally posted by agrysonPersonally I have been waiting around breathlessly for the rovers to go over some hill and find a big thigh bone sticking out of a cliff or something but no such luck yet.
the theory of 'panspermia' (life travelling between planets) does not rely on intelligent beings sending that life. Enormous amounts of martian rock (comparatively) have reached earth with no intelligent intervention. Also, even if their genetic coding was of an entirely different structure to our DNA, that does not preclude a common ancestry, provided the p more and more coincidences such as this occuring every year.
Just something to think about.
