   Explanation: What's the sound of [3]one laser zapping? There's no need
   to consult a Zen master to find out, just listen to the first
   [4]acoustic recording of laser shots on Mars. On Perseverance mission
   sol 12 (March 2) the SuperCam instrument atop the rover's mast zapped a
   rock dubbed Ma'az 30 times from a range of about 3.1 meters. [5]Its
   microphone recorded the soft staccato popping sounds of the rapid
   series of SuperCam laser zaps. Shockwaves created in the thin martian
   atmosphere as bits of rock are vaporized by the laser shots make the
   popping sounds, sounds that offer clues to the physical structure of
   the target. [6]This SuperCam close-up of the Ma'az target region is 6
   centimeters (2.3 inches) across. Ma'az means Mars in [7]the Navajo
   language.
