Gimpy rover has turned up a surprise on Mars / Jammed front wheel plowing surface has uncovered signs of habitability in silica

Gimpy rover has turned up a surprise on Mars / Jammed front wheel plowing surface has uncovered signs of habitability in silica: "On the opening day of the American Geophysical Union's annual meeting in San Francisco on Monday, Steven Squyres of Cornell, the Mars mission's principal investigator for science, disclosed that the rover's dragging wheel has serendipitously been working as a plow and has turned over yards and yards of Martian crust to reveal a startlingly white track of almost pure silica - the material that makes ordinary glass. The tracks also reveal small amounts of titanium."
