Currently in the twelfth year of its mission, NASA's Curiosity rover continues to press on while treading the world of Mars, delving into areas no rover has gone before. The latest phase of Curiosity's adventure has brought it to what some scientists believe is the desiccated bed of an ancient river. 

As Curiosity prepares to follow Gediz Vallis, as scientists call this winding and boulder-choked channel, it will try to give scientists a look back through time so they can discover how the landform came to be in the first place
