"Curiosity," the nuke-powered, Mini Cooper-sized Mars rover, will aim for deep Gale crater.


Gale Crater is about 155km in diameter, and its lowest point is about 4.6km below datum, an imaginary "sea level"-type reference point on Mars from which all other elevations are measured.

Gale contains a central peak that should reveal stratigraphy ranging from Mars' wet period through the long drying out to the dessicated present.
