NASA Studies Life's Limits in China's Extreme Deserts

Could there be life on Mars? Earths deserts suggest that there could be. Scientists are using some of the most extreme places on earth to test to see if there could possibly be life on earth. The most recent study was done in China's northwest region in one the worlds oldest and driest deserts. The study found evidence that suggests that Mars may have similar conditions and so may have some form of tiny life forms.
