Tweedledee Posted September 28, 2015 Share Posted September 28, 2015 Will NASA announce seasonal rivers on Mars? Looking forward to finding out this afternoon. Link to comment Share on other sites More sharing options...
tuckstar Posted September 28, 2015 Share Posted September 28, 2015 Heard rumours it might be to do with the methane discovery earlier in the year as well. Link to comment Share on other sites More sharing options...
Brantuk Posted September 28, 2015 Share Posted September 28, 2015 Dunno what they'll do with the knowledge of water on Mars - if that's what it is. I guess the suicide mission to Mars can be assured of a drink at the end of it (assuming they make it there alive) lol.

Tibbz2 Posted September 28, 2015 Share Posted September 28, 2015 News sites have posted that it's evidence of liquid water on mars: https://www.newscientist.com/article/dn28251-salty-water-seen-flowing-on-mars-not-far-from-curiosity-rover/?utm_source=NSNS&utm_medium=SOC&utm_campaign=twitter&cmpid=SOC%7CNSNS%7C2014-GLOBAL-twitter Link to comment Share on other sites More sharing options...
Smithysteve Posted September 28, 2015 Share Posted September 28, 2015 Water on Mars! Whatever next......... Canals? This seems like an old story â˜ºï¸ tuckstar and Astronigel 2 Link to comment Share on other sites More sharing options...

Smithysteve Posted September 28, 2015 Share Posted September 28, 2015 They've never had evidence of liquid water before Lol, I was referring, tongue in cheek, to Percival Lowells canals on Mars ... ☺ https://en.m.wikipedia.org/wiki/Percival_Lowell#Canals_of_Mars tuckstar 1 Link to comment Share on other sites More sharing options...
stash Posted September 28, 2015 Share Posted September 28, 2015 Done in a Welsh voice for effect “No one would have believed in the early years of the 21 century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water.†queue music Bet there's more life on Pluto!

Tweedledee Posted September 28, 2015 Author Share Posted September 28, 2015 Bet there's more life on Pluto! Don't think there is much chance on Pluto which is about 200 degrees C colder than Mars. Link to comment Share on other sites More sharing options...
Tweedledee Posted September 28, 2015 Author Share Posted September 28, 2015 (edited) I know there are extremophile organisms on earth that can survive in high concentrations of acid or alkali, but if this liquid water on Mars is at about 23 degrees Centigrade below its normal freezing point, it must be extremely concentrated with salts. You'd struggle to keep your windscreen washer fluid spraying at -23 . Along with the cold temperatures, this would probably make it even more difficult for anything to survive. But then, who knows what extreme extremophiles could have evolved on Mars. It is still an exciting discovery .

Time will tell - At least Pluto has Nitrogen as it main component bit more than earth. Plus people said the same about the deepest oceans "there's no light , too much pressue" - well look now - highly saline water that may reach 300 °F plus massive pressure - Pluto may have moving ICE(Methene) that means friction - that means methene melts. So never say never. Link to comment Share on other sites More sharing options...
