Does there exist a list of all the evidence of water on Mars, listed by spacecraft?
Ideally, it would be a list with a short description and a link to a story or news release. For example: Mars Global Surveyor: NASA Images Suggest Water Still Flows in Brief Spurts on Mars http://www.nasa.gov/mission_pages/mars/new...s-20061206.html Phoenix: NASA Spacecraft Confirms Martian Water, Mission Extended http://www.nasa.gov/mission_pages/phoenix/...x-20080731.html Opportunity: NASA Mars Rover Finds Mineral Vein Deposited by Water http://www.nasa.gov/mission_pages/mer/news/mer20111207.html I know I could spend some time and extend the list that I've started above, but if someone or some organization has already done it I'd hate to reinvent the wheel! Thank you. |

This makes me wonder: If ice, at a lattitude and altitude that put temperature and pressure in the 'liquid water range', were exposed ona sunwards facing slope today (by landslide, impact, man digging with shovel, whatever) how much hydration would the immediate surroundings actually get? Because, as I understand it, even when Martian conditions are at their most water-favourable only small amounts would form, and only briefly.
I could believe however that a liquid water pocket(s) might form beneath the translucent surface of said exposed ice, and find its way surfacewards - but it still seems as though the surroundings wouldn't get very 'wet'. I do recall experiments with pure ice under martian conditions being done, but cannot find them Of course 'chemically enhanced' (antifreeze of some kind laden) water would be more stable.... -------------------- |

On Earth you will often find water under a glacier, on Mars the temperature is lower so it might only happen under special conditions, and if the glacier is on top of an area with a lot of salts such brine is then potentially possible.
Since Mars is thought to be in a current ice age, this report also adds a piece to the puzzle on where the 'missing' water ended up. Some images from orbit have shown what might be comparatively recent water flows, with only few or nearly no craters. So I found this interesting since these glaciers might be part of the hydrological cycle when the climate switch to a more benign state. |
