Salty lake, ponds may be gurgling beneath South Pole on Mars
CAPE CANAVERAL-The Associated Press
Italian scientists reported their findings on Sept. 28, two years after identifying what they believed to be a large buried lake. They widened their coverage area by a couple hundred miles, using even more data from a radar sounder on the European Space Agency’s Mars Express orbiter.
In the latest study appearing in the journal Nature Astronomy, the scientists provide further evidence of this salty underground lake, estimated to be 12 miles to 18 miles (20 kilometers to 30 kilometers) across and buried 1 mile (1.5 kilometers) beneath the icy surface.
Even more tantalizing, they’ve also identified three smaller bodies of water surrounding the lake. These ponds appear to be of various sizes and are separate from the main lake.
