I saw something interesting on the news tonight. Apparently, a bunch of salt crystals were found in the New Mexican desert, which used to be part of a shallow ocean. The scientists noticed little tiny droplets of water incased in the salt crystals. They drilled in to the crystal and extracted the water. When viewed under the microscope, yep, you guessed it, life. The bacteria were squirming and reproducing all over the place.
Are the Mars rovers going to be looking for salt? If salt is found, what types of experiments will the rovers be able to perform? I suppose just finding salt that could be left over from a sea would be spectacular. I just keep thinking, what if?
