    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
