Salty lakes the size of Scotland could be buried beneath Martian pole
"New evidence has been revealed of an enormous salty lake of liquid water buried beneath the ice of the Martian south pole.
New radar data from a European Space Agency spacecraft suggests a large body of liquid water, as well as three smaller lakes, are spread out over 75,000 square kilometres - an area roughly the size of Scotland.
There is potential that the liquid water - if that is what it is - could harbour life. However, its extreme salinity could also make it uninhabitable."
