NASA's Opportunity rover has been sending images of Mars back to Earth since 2004. Now, computer scientist Mark Powell, of NASA's Jet Propulsion Laboratory, has developed a free app for iPhone and Android that wires these photos directly to your phone.
The app is called called, quite simply, "Mars Images." Mars Images automatically updates with all of Opportunity's latest snapshots of the Martian surface. So the next time the rover captures an image like the one up top — which NASA scientists have since described as the most "bullet proof" evidence yet of Mars' watery past — you'll be one of the first to see it!
