Abstract

The discovery of high concentrations of water-ice just below the Martian surface in polar areas by the Mars Odyssey spacecraft has strengthened the debate about the possibility of life on Mars. Generally, it is believed that life on Earth emerged in liquid water through the processing of organic molecules. The possible origin of life on early Mars would have been related to the evolution of the planetary water inventory, so it is important to estimate the present amount of water-ice below the planetary surface.
