    NASA Curiosity Mars rover has surpassed 100,000 laser shots with its ChemCam instrument that help scientists identify what elements make up the Martian surface in Gale Crater.

    NASA’s Curiosity Mars


    rover has officially fired the laser it uses to check chemical


    elements in rock over 100,000 times.  The laser is used by the


    ChemCam instrument to excite plasma from rock, which the Chem


    Cam telescope can then observe the spark that flies off the rock


    and the spectrum of light to identify the elements in the target.  The


    rover fired its 100,000


    fired more than 102,000 shots while assessing more than 420 rock


    or soil targets. The information achieved is being used by scientists


    and students to identify what makes up the Mars surface inside


    Gale Crater.  NASA said passing the 100,000 laser shot mark is


    “terribly exciting and is providing a remarkable set of chemical data




     shot back in November and by now has
