curiosity

This does NOT mean that anything ever actually lived there. But it is the first time that the ingredients for the evolution of microbial life, and the correct conditions to support it, have been directly observed beyond Earth. Mars still has water frozen at its poles, and once had quite a bit of water above and below the surface.

On August 5 of this year, NASA will be sending the rover Curiosity to Mars. Or at least they'll try, as this shows us the hundreds of things that need to go right for a rover to land on the surface of Earth's red cousin.

Just wait until Avatar 2...
