Blog Post Image: Laser Instrument on NASA Mars Rover Tops 100,000 Zaps

Since landing on Mars in August 2012, NASA’s Curiosity Mars rover has fired the laser on its Chemistry and Camera (ChemCam) instrument more than 100,000 times at rock and soil targets up to about 23 feet (7 meters) away. This mosaic of images from ChemCam’s remote micro-imager camera show the rock, called “Ithaca,” that received the 100,000th zapping, and 299 others. The scale bar at upper right is 1 centimeter (0.4 inch). The target was 13 feet, 3 inches (4.04 meters) from the top of Curiosity’s mast, where the laser and remote micro-imager are mounted, when the rock was inspected during the 439th Martian day, or sol, of the rover’s work on Mars (Oct. 30, 2013).
