Scientists have unveiled new evidence which they say proves water could be flowing on Mars right now -- a claim that could debunk the long-held belief that the Red Planet has been completely dry for billions of years. Lujendra Ojha and a number of his fellow academics at the Georgia Tech have proposed that the dark, finger-shaped features on Martian slopes which disappear and reappear as seasons change are, in fact, flows of saltwater. RT's Liz Wahl asks Ojha if the discovery of water on Mars could one day soon lead to the colonization of the Red Planet.
