Scientists believe that NASA's Phoenix Mars lander exposed bits of ice while recently digging a trench in the soil of the Martian arctic, the mission's principal investigator said Thursday.

Cool ... however I read an article somewhere that the salinity of any water on Mars would be too high to support life, way beyond the levels in the Dead Sea, and so the osmotic potential would suck all water out of living organisms.

and i read somewhere that most of the crap you read about things nobody knows is just that ... crap. there are organisms here on earth that live in water 3 times saltier than the oceans that would kill you if you drank it... i digress ... we don't know yet IF there is water there... |

Judged: 1 1 It hasn't been proven that ALL the water on Mars was like this. For example, if a probe landed on Earth and sampled the water from the Dead Sea, thats a huge difference then if it had sampled from Lake Superior. If the Phoenix had found salty ice, there would have been a residue of salt left after the water sublimated. That's why I want to see what the deeper digging uncovers. |

Judged: 3 3 1 Does this have to be political? There are plenty of forums for complaining elsewhere. |
Believe only half thatis written, and absolutely nothing that you hear,
As the famous gravestone said, "here lies a politician" Mind you I prefer, "Under this slab John Brown is stowed, he watched the ads and not the road" Lord Byrons grave was even better, "Ner're has God seen such a glorious place as this so stay a while and have a p-ss" |

Judged: 1 1 1 The article was in the Economist, this is the last part of it ..... <<Mars's geology (if that is not an oxymoron) has been studied spectroscopically by several satellites, and has also been prodded and probed at a local level by ground-based rovers. The upshot is that the layered rocks do, indeed, seem to have formed underwater. They appear to be sandstones, but with a lot of minerals such as magnesium, calcium and iron sulphates that form when brine evaporates. It is these minerals that concern Dr Tosca. His calculations suggest that the waters they formed from would have been highly acidic. That is bad enough for those who imagine them brim-full of bacteria. But they would also have been highly osmotic. The dissolved chemicals within them would have served to lock up the water so that it could not take part in biochemical reactions. The degree to which water is locked up by such solutes is measured by a number called the “water activity” of a solution. Pure water has an activity of 1.0. Seawater's activity is 0.98. The water of primeval Mars, Dr Tosca calculates, was probably between 0.78 and 0.86, and may sometimes have been as low as 0.5. That is far lower than is tolerable by any living thing known on Earth, even from places like the Dead Sea. This result will probably not dampen the ardour of exobiologists. Living organisms, they will argue, are amazingly adaptable, so why should they not be born in conditions even more extreme than those found on Earth? Like a phoenix, perhaps. But then the phoenix is mythological. >> |
Judged: 1 I'm waiting for the screw-up shot that shows cables and a camera in the frame. That's the most imaginative staged shot yet. Good job. Did they shoot that at American AV? |

I'd have checked the pH of the inner shell with a Specronometer. |
