Water on Mars

I just thought I'd bring up the discovery that Mars' northern pole has between 2 - 3 million cubic kilometres of ice (about 95% pure). This is about 100 times the volume of North America's Great Lakes. On Earth there are about 41 million cubic kilometres of freshwater. About 69% is thought to be locked into permanent ice and snow. About 30% is located within soil and aquifers. This leaves about 1% or 0.41 million cubic kilometres to run free on the surface. A large number of people get drinking water from aquifers, but this suggests that with wise management, Mars' water should be able to support a population substantially larger than what now exists on Earth.

Very cool site. You should keep up with it. I'm sure many of us who are gardeners during the day are stargazers at night.

Thanks for commenting. I have a lot of interests and sometimes I drift away from some for a time. I almost always end up coming back though...

Have you read Red Mars? Since it is about terraforming Mars, thought you'd like it. The first in the trilogy is the best.
