For the first time, satellite imagery reveals thick Martian salt deposits scattered across the planet's southern surface, which one planetary scientist claims could be sites of ancient life.
The mats of sodium chloride — the same taste-enhancing mineral found on your kitchen table — serve as more evidence of Mars' watery past, and researchers think the briney pools that made them could have been hospitable to life.
"If you're trying to find life on Mars, the more and different places that exist, the better the chances are that one of them is going to have the right conditions," said Phil Christensen, a planetary geologist at Arizona State University. "It takes a lot of water to form salt, so this is another place to look."
