Summary:
NASA's Curiosity Mars rover has passed the milestone of 100,000 shots fired by its laser. It uses the laser as one way to check which chemical elements are in rocks and soils.

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).

The 100,000th shot was one of a series of 300 to investigate 10 locations on a rock called "Ithaca" in late October, at a distance of 13 feet, 3 inches (4.04 meters) from the laser and telescope on rover's mast. The Chemistry and Camera instrument (ChemCam) uses the infrared laser to excite material in a pinhead-size spot on the target into a glowing, ionized gas, called plasma. ChemCam observes that spark with the telescope and analyzes the spectrum of light to identify elements in the target.

"Passing 100,000 laser shots is terribly exciting and is providing a remarkable set of chemical data for Mars," said ChemCam co-investigator Horton Newsom of the University of New Mexico, Albuquerque.

As of the start of December, ChemCam has fired its laser on Mars more than 102,000 times, at more than 420 rock or soil targets. Virtually every shot yields a spectrum of data returned to Earth. Most targets get zapped at several points with 30 laser pulses at each point. The instrument has also returned more than 1,600 images taken by its remote micro-imager camera.

An international team of scientists and students is mining information from ChemCam to document the diversity or materials on the surface inside Mars' Gale Crater and the geological processes that formed them. "These materials include dust, wind-blown soil, water-lain sediments derived from the crater rim, veins of sulfates and igneous rocks that may be ejecta from other parts of Mars," Newsom said.

Each pulse delivers more than a million watts of power for about five one-billionths of a second. The technique used by ChemCam, called laser-induced breakdown spectroscopy, has been used to assess composition of targets in other extreme environments, such as inside nuclear reactors and on the sea floor. Experimental applications have included environmental monitoring and cancer detection. NASA's Mars Science Laboratory Project, using the Curiosity rover, is the first mission to use it on another planet.

ChemCam is one of 10 instruments in Curiosity's science payload. The U.S. Department of Energy's Los Alamos National Laboratory, Los Alamos, N.M., developed ChemCam in partnership with scientists and engineers funded by the French national space agency, CNES, the University of Toulouse and research agency, CNRS. The laser was built by Thales, Paris. More information about ChemCam is available at http://www.msl-chemcam.com .

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project, including Curiosity, for NASA's Science Mission Directorate, Washington. JPL designed and built the rover.
