February 17, 2007       International More evidence of water on Mars This image provided by Science shows light-toned layered rock in Becquerel Crater on Mars as photographed by the HiRISE (High Resolution Imaging Science Experiment) camera on board Nasa's Mars Reconnaissance Orbiter. The orbiter images show alternating layers of dark and light-toned rock within which are a series of fractures, surrounded by what researchers call 'halos' of light-toned bedrock. These halos are believed to indicate where fluids, probably water, passed through the bedrock. PHOTO: AP
