Mars soil contains a huge amount of water, reports NASAs Curiosity rover

2013-09-27 17:02:41| Extremetech

If you heat up a cubic foot of Mars soil, you can harvest around two pints (one liter) of water. According to new data returned by NASA's Curiosity rover, this isn't just a one-off lucky find, either: It seems that most of the dirt on Mars harbors large amounts of water. This is very exciting news for future human exploration of Mars, because it's prohibitively difficult to transport water from the surface of Earth to the Red Planet -- and, in one fell swoop, it also makes the eventual terraforming and colonization of Mars a lot more feasible.
