Liquid water beneath Martian south polar cap?

Scientists measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements support oddly bright reflections detected by the MARSIS subsurface sounding radar aboard ESA's Mars Express orbiter.
