Far beneath the deeply frozen ice cap at Mars's south pole lies a lake of liquid water—the first to be found on the Red Planet. Detected from orbit using ice-penetrating radar, the lake is probably frigid and full of salts—an unlikely habitat for life. The lake resembles one of the interconnected pools that sits under several kilometers of ice in Greenland and Antarctica, but the processes that gave rise to a deep lake on Mars are likely to be very different. The discovery is sure to intensify the hunt for other buried layers of water that might be more hospitable.
