This composite image, with magnified insets, depicts the first laser test by the Chemistry and Camera, or ChemCam. The widest context view in this composite comes from Curiosity's Navigation Camera. The magnified views in the insets come from ChemCam's camera, the Remote Micro-Imager. The area shown in the circular inset is 6 centimeters (2.4 inches) in diameter. It was taken before the rock was hit with the laser. The area covered in the further-magnified square inset is 8 millimeters (about one-third of an inch) across. It combines information from images taken before and after the test, subtracting the "before" image from the "after" image to make the changes in the rock visible.
