New Evidence for Liquid Water Beneath the South Polar Ice Cap of Mars

New evidence for liquid water beneath the south polar ice cap of Mars
The left-hand panel shows the surface topography of Mars’s south pole, with the outline of the south polar cap in black. The light blue line shows the area used in the modelling experiments, and the green square shows the region containing the inferred subglacial water. The ice in the region is around 1500 m thick. The right-hand panel shows the surface undulation identified by the Cambridge-led research team. It is visible as the red area, which is elevated by 5-8 m above the regional topography, with a smaller depression (2-4 m below the regional topography) upstream (towards the top right of the image). The black outline shows the area of water as inferred by the orbiting radar. Credit: University of Cambridge
