The Solar System Has a Lot of Water

I wrote about the various places you can find water in the solar system on Three Alpha:

There have been a couple of recent discoveries of water in new places in the solar system. Last week a team using data from India’s Chandrayaan-1 probe announced the discovery of water ice on the surface of the Moon, and last month researchers using radar data from the European Space Agency’s Mars Express mission announced the discovery of liquid water under the south polar ice cap on Mars. These aren’t the first discoveries of water on other worlds – water is actually pretty common.
