After landing safely on Mars last month, NASA's Curiosity rover (right) has begun its journey to a nearby canyon. Captured by the Mars Reconnaissance Orbiter from high above the red planet, this color-enhanced image, released Thursday, shows Curiosity's tracks.
The orbiter's high-powered cameras were designed to detect even slight details on the planet's surface. The sky crane that lowered Curiosity onto Mars threw up enough dust that scientists back on Earth can now see a darker, more mysterious rocky substrate below-the blueish spots at center.
