Martian Trek

Rocks rich in silica similar to those in the oldest part of Earth's continental crust are scattered throughout the area where NASA's Curiosity probe is exploring on Mars, according to a study published on Monday in Nature Geoscience.

NASA's Curiosity Mars rover has completed a 100.3 metre backwards drive over the Martian terrain - the longest one-day trek in more than three months.
