Curiosity Mars Rover's Summer Road Trip Has Begun
NASA's Curiosity Mars rover has started a road trip that will continue through the summer across roughly a mile (1.6 kilometers) of terrain.

Located on the floor of Gale Crater, Mount Sharp is composed of sedimentary layers that built up over time. Each layer helps tell the story about how Mars changed from being more Earth-like - with lakes, streams and a thicker atmosphere - to the nearly-airless, freezing desert it is today.
