Scientists say images of Martian craters taken by European and American space probes show there was once probably a planet-wide system of underground lakes.
Researches in Italy and the Netherlands say data collected by Nasa and ESA probes orbiting the red planet provide the first geological evidence for a large groundwater system on Mars.
Ralf Jaumann, a planetary scientist at the German Aerospace Centre who was not directly involved in the study, said future Mars landers will be examining the craters for signs of ancient life.
