LANL's ChemCam conducts first laser test over the weekend

Posted By Office of Public Affairs

ChemCam

NASA's Mars rover Curiosity fired its laser for the first time this weekend on Mars, using the beam from a science instrument to interrogate a fist-size rock.

The mission's ChemCam, designed and built at Los Alamos National Laboratory, hit the fist-sized rock with 30 pulses of its laser during a 10-second period. Each pulse delivers more than a million watts of power for about five one-billionths of a second.
