Title: Mars Rover finds more evidence of water
Post by: Flipside on September 27, 2012, 05:22:28 pm: http://www.bbc.co.uk/news/science-environment-19744131

Basically, the rover has discovered what looks very much like an ancient streambed on Mars :)

I'm looking forward to further analysis of Mars' methane. If it's biological in origin that would be freaking awesome. :)

Indeed...that would be awesome indeed. :nod:

Well, I meant liquid water. Ice on Mars is old news.

passed out from the testing protocal?

:rolleyes: Passed gas, that is a polite way of saying someone farted. Being it's methane. Just a jest, a gag.

That's unfortunately impossible for the vast majority of Mars' surface. The average surface air pressure on Mars is lower than water's triple point, therefore water can't exist in the liquid phase regardless of what the temperature is. (If you warm ice at such pressure, it just sublimates instead of melting. See phase diagram (http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/Phase_diagram_of_water.svg/700px-Phase_diagram_of_water.svg.png)). That said, the pressure is variable with seasons, and at very low altitudes like Hellas Basin can be high enough to support liquid water, if the temperature is also above 0°C.
