In the last few years, evidence arguing for the possibility of life on Mars has been piling up. The presence of ice on Earth's red neighbor is now established, but for microbial organisms to live, liquid water is necessary. This week, scientists announced that they may have found just that, reported the New York Times.Photos taken by NASA's Mars Reconnaissance Orbiter during the planet's spring, summer and winter seasons in 2006 reveal dark streaks that may be water flowing downhill. The current hypothesis is that the streaks represent salt water, which wouldn't freeze on the icy planet.
But confirmation of flowing water is a long ways off. Unfortunately, no rover will be visiting the area where the streaks were identified anytime soon. For now, we'll just have to wait, or maybe get ready to move to Mars and check it out for ourselves.
