Drilling Success: Curiosity is Collecting Mars Rocks
Engineers working with NASA's Curiosity Mars rover have been hard at work testing a new way for the rover to drill rocks and extract powder from them. This past weekend, that effort produced the first drilled sample on Mars in more than a year.
Curiosity tested percussive drilling this past weekend, penetrating about 2 inches (50 millimeters) into a target called "Duluth.".
