This image from NASA's Curiosity rover shows the first sample of powdered rock extracted by the rover's drill. The image was obtained by Curiosity's Mast Camera on Feb. 20, or Sol 193, Curiosity's 193rd Martian day of operations.

"We're sort of seeing a new coloration for Mars here, and it's an exciting one to us," Joel Hurowitz, sampling system scientist for Curiosity at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., told reporters Wednesday (Feb. 20).
