Whoa, Mars might have as much water underground as Earth does

If you’re planning on helping to colonize Mars, you’ll be thrilled to hear that a recent analysis of Martian meteorites indicates that there may be more water on Mars than we previously thought — a lot more. Scientists now think that the amount of water that’s underground on Mars could rival that of Earth. The discovery has rekindled speculations about the red planet’s ability to sustain life — including, potentially, that of human visitors.
