A partial view of the Martian south polar ice cap, taken on 11 February 2004 during orbit 103 by the High Resolution Stereo Camera on Mars Express, from an altitude of 269 kilometres. The south pole is where the OMEGA instrument made its significant discovery, with the steep slopes known as –scarps´ made almost entirely of water ice, falling away from the polar cap to the surrounding plains, and the permafrost fields that stretch for tens of kilometres away from the scarps.

Artist´ impression of water under the martian surface. If underground aquifers like that really do exist, Mars Express has a good chance of finding them. The implications for human exploration and eventual colonisation of the red planet would be far-reaching. Credits: Illustration by Medialab, ESA 2001

(A) MARSIS data showing typical features of the SPLD. (B) MOLA topography along the ground track. The lower echo trace (arrows) is interpreted as the SPLD basal interface with the substrate. The basal reflector becomes indistinct right of center. The central area shows multiple continuous bands internal to the SPLD, where the estimated SPLD thickness is 1.6 km. (C) MARSIS data showing a bright basal reflector (arrow). (D) MOLA topography along the ground track. The reflector extends from the margin of the SPLD (left of center) to below a 3.5 km thick section of the SPLD. The basal reflector abruptly disappears for unknown reasons. (E) MOLA surface elevations (black line) and MARSIS measured basal elevations (blue symbols), assuming a refractive index of ice. The basal reflector is at a fairly constant elevation between 1000 and 1500 m. The apparent curvature of the reflector in (C) is an artifact of the time representation of the data. Vertical dimension in (A) and (C) is round trip travel time. Credits: NASA/JPL/ASI/ESA/Univ. of Rome/MOLA Science Team

Topography of the south polar region of Mars from MGS MOLA data, with locations of MARSIS measurements of the SPLD thickness shown as open circles. SPLD unit as mapped by (15) is outlined in black. Red lines indicate ground tracks of orbits. Apparent gaps in coverage are due to the lack of a discernible basal interface, and not to gaps in observations. No MARSIS data are available poleward of 87° S (dark circle in upper center).

Map of the SPLD thickness, based on MARSIS measurements and MOLA surface topography. An anomalous thick section appears in lower right.

The upper image of this composite is a –radargram´ from the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) on board ESA´ Mars Express. It shows data from the subsurface of Mars in the water-ice-rich layered deposits that surround the south pole of the planet.
The lower image shows the position of the ground track of the spacecraft (indicated by a white line) on a topographic map of the area based on data from the MOLA laser altimeter on board NASA's Mars Global Surveyor.

These images provide a comparison between the water-ice accumulation rates in the
present day and 21,500 years ago. Present-day map shows a net accumulation of
water-ice only at the South Pole itself, where the existence of a CO2 cold-trap
forces a local and permanent deposition of water-ice. In the inversed situation
(21,500 years ago), the CO2 cold trap has been removed and the pattern of
accumulation is only controlled by the precipitation/sublimation of water vapor on
an annual average.
