Planetary science: Picturing a recently active Mars
Victor R. Baker1
Abstract
Discoveries made with the High Resolution Stereo Camera on the Mars Express orbiter show that, as recently as a few million years ago, the surface of Mars was being shaped by flowing water, lava and ice.
Spectacular ground-based images and chemical analyses of ancient sedimentary rock formations1 leave no doubt that Mars had a watery ancient past. These discoveries by NASA's Mars Exploration Rover Mission apply to the Noachian epoch of Mars history — the first several hundred million years of the Solar System, when the impact rate of meteors and comets was much higher than in the past 3–4 billion years2.
