    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

    New research suggests that deep groundwater could still be active on Mars and could originate surface streams in some near-equatorial areas on Mars. In mid-2018, researchers supported by the Italian Space Agency detected the presence of a deep-water lake on Mars under its south polar ice caps. Now, researchers at the USC Arid Climate and Water Research Center (AWARE) have published a study that suggests deep groundwater could still be active on Mars and could originate surface streams in some near-equatorial areas on Mars.

    The researchers at USC have determined that groundwater likely exists in a broader geographical area than just the poles of Mars and that there is an active system, as d...

    Mars Express detects Liquid Water Hidden under Planet’s South Pole

    Radar data collected by ESA’s Mars Express point to a pond of liquid water buried under layers of ice and dust in the south polar region of Mars. Evidence for the Red Planet’s watery past is prevalent across its surface in the form of vast dried-out river valley networks and gigantic outflow channels clearly imaged by orbiting spacecraft...
