Houston, we have a destination! After much design, testing and budget-wrangling, the NASA Curiosity Rover now "knows" where it will land and explore come August 2012. The crater is called Gale, and it's a promising site for water and life.

Mostly water though, as the features found in and around the 96-mile-wide crater were believed to have been formed by water.
