Scientists see dark 'tendrils', signs of flowing water, emerge from rocky Martian outcrops
Striking new images from the mountains of Mars may be the best evidence yet of flowing, liquid water, an essential ingredient for life.
The findings, reported today in the journal Science, come from a joint US-Swiss study.
A sequence of images from the Mars Reconnaissance Orbiter show many long, dark "tendrils" a few metres wide.

Earthlings need to get there fast and teach them how to swim.

The gravity on mars is about 38% of what it is on earth. A 200 lb man would weigh about 76 lbs on mars. That’s more than enough for a flow of fluid

Does Mars have gravity? Yes, of course, it has mass, therefore it has gravity. Mars has a bit over one third of Earth's gravity.

Aye, any mass has gravity- .38 times your weight equals your weight on Mars. Very interesting, now to get a water sample... thats going to be a long time coming.

The atmospheric pressure on Mars is about 1/1000 that of Earth. Any liquid on the surface would evaporate almost instantly.

Does Mars have gravity? Knarf old buddy - you are kidding, right?

remember that is a very salty brine, not pure water. The phase diagram of temp/pressure is shifted.
