ChemCam's first target
Scroll Right Scroll Left

This mosaic image shows the first target NASA's Curiosity rover aims to zap with the ChemCam instrument. ChemCam will be firing a laser at this rock, provisionally named N165, and analyzing the glowing, ionized gas, called plasma, that the laser excites. The instrument will analyze that spark with a telescope and identify the chemical elements in the target.
