More Evidence of Water Found on Mars

New images of a craggy, fissure-filled canyon on Mars provide evidence of long-term underground water flows that may have provided a suitable environment for microbial life, scientists say. The new findings show light-coloured features cutting across dark bands in an area known as Candor Chasma. Dr Okubo and his colleagues believe they are looking at places where rock has been chemically altered by water flowing across the fractures
