      Radar reveals ice deep below Martian surface

      MARSIS images from two different overhead passes reveal a 250-
      km-wide buried impact basin. In the lower image, a linear
      reflection nearly parallel to the surface is seen embedded in
      the arcs – this may be the result of liquid water

      MARSIS probed under the icy deposits at the north pole,
      revealing that they are 1.8 km thick in the region studied. The
      deposits appear as a layer on the right of the upper image
      (Image: ASI/NASA/ESA/Univ. of Rome/JPL/MOLA Science Team)The
      first ever underground investigation of another planet has been
      performed by a radar antenna aboard Europe's Mars Express
      spacecraft. The instrument probed two kilometres below the
      Martian surface and found tantalising hints of liquid water
      pooling in a buried impact crater.
