Julian Joachim Jr Shabadoo Posted 29 September 2015 Posted 29 September 2015 For some reason, all I could picture there was Frank Grimes bringing the water in and explaining how important it is, and Homer snatching it to drink. That's what I was thinking when I wrote it! Best episode ever "Take me out to the ball game. Take me out to the balllllllll! So..... what's new Grimy?"
AyewJoking Posted 29 September 2015 Posted 29 September 2015 water is essential to life on earth, what makes them think its essential to life on mars. its like a whole other planet!!
leicsmac Posted 29 September 2015 Posted 29 September 2015 water is essential to life on earth, what makes them think its essential to life on mars. its like a whole other planet!! You've hit on a pretty essential point regarding our view on life there - one of the reasons why the Drake Equation (the idea that the odds are in favour of life in other places because of the sheer number of planets and stars out there) falls down...the fact that our entire viewpoint on life is based on what we know of life on Earth. Carbon-based life that synthesises energy through either respiration (turning sugars and water to energy) or photosynthesis to help it along, or a mixture of both. The truth is that life in other places could operate in an entirely different way to that on Earth. That being said, the idea behind live surviving is that it must use simple chemical compounds to do so (using them for energy in some way), and I honestly don't think would be any different for the way life is in other places. They may not need water, but that or other simple compounds like it are a good place to start looking.
MooseBreath Posted 29 September 2015 Posted 29 September 2015 Would we need to bring the sample of water back to earth? Couldn't we just pop another rover over with a sampling and analysing kit? Also, if Mars was teeming with life in the past wouldn't there be loads of fossils and stuff in the rock? Oil and whatnot that we could find with a drilling rig.

Also, if Mars was teeming with life in the past wouldn't there be loads of fossils and stuff in the rock? Oil and whatnot that we could find with a drilling rig. For a definitive answer, yes. The kind of equipment we'd need to analyse the water for organic compounds caused by life is not only sizeable and heavy but also not the kind of stuff that you can operate with a remote or using a computer program at that kind of distance. It's possible we could do some simple sampling to get an idea of whether or not it's worth bringing the sample back in the first place, but for the real deal it's got to be done here. As for the fossils, it depends on the kind of rock out there. If there's a lot of sedimentary rock there's a possibility there could be fossils, but given that the odds of a living creature getting fossilised for long enough for us to find it are pretty astronomical it would mean that there would have had to have been a hell of a lot of them for a long period of time - just like on Earth. Also, Mars has a shitload of volcanic activity so the rocks get turned over and about on a pretty regular basis, so that doesn't help. It would be brilliant to find one up there, though. Doubt there'd be much oil there as if life did exist there it's highly unlikely it was complex enough and in big enough quantity to produce much, and thanks to the aforementioned volcanic activity it would be very well buried..
MPH Posted 29 September 2015 Posted 29 September 2015 But we'll need somewhere to f**** off to when we've screwed this planet. It'a a god awful small affair..... But Mars is clearly uninhabitable for humans anyway... we already know that.... Just think of all the Guns Americans could buy with all those billions of Dollars!* * Or affordable housing/food/ clothing
purpleronnie Posted 29 September 2015 Posted 29 September 2015 Not mine, but fits: Not really. The fact we exist mean we did everything right.
Trav Le Bleu Posted 29 September 2015 Posted 29 September 2015 Surely what they actually found is evidence of liquid on Mars.
Great Boos Up Posted 29 September 2015 Posted 29 September 2015 Surely what they actually found is evidence of liquid on Mars. Rivers of alcohol ! Which way is NASA ?
