Summary

Description	English: 10.22.2012 Laser Hit on Martian Sand Target, Before and After http://photojournal.jpl.nasa.gov/catalog/PIA16234 The Chemistry and Camera (ChemCam) instrument on NASA's Mars rover Curiosity used its laser and spectrometers to examine what chemical elements are in a drift of Martian sand during the mission's 74th Martian day, or sol (Oct. 20, 2012). This pair of images from ChemCam's remote micro-imager shows the target, called "Crestaurum," before and after it was zapped 30 times by the instrument's laser. The dark pit created by the repeated laser hits is about one-eighth of an inch (3 millimeters) across. Crestaurum is within the "Rocknest" patch of windblown dust and sand. It was selected as a target surfaced with fine-grain sand. The distance to the target from the ChemCam instrument at the top of Curiosity's mast was 8 feet and 10 inches (2.7 meters).
