激光击打的声音是什么？没有必要去请教禅师，只需要听听火星上激光射击的第一个录音。在“毅力号”火星探测器第12次任务中（2021年3月2日），探测器桅杆上的超级摄像机从3.1米的距离拍摄了一块名为Ma'az的岩石30次。它的麦克风录下了SuperCam激光快速射击时发出的断断续续的声音。在火星稀薄的大气层中，当岩石碎片被激光射击蒸发时，产生的冲击波会发出爆裂的声音，这种声音为目标的物理结构提供了线索。这张超级摄像机拍摄的马阿兹目标区域的特写是6厘米（2.3英寸）宽。Ma'az在纳瓦霍语中的意思是火星。

What's the sound of one laser zapping? There's no need to consult a Zen master to find out, just listen to the first acoustic recording of laser shots on Mars. On Mars Rover Perseverance mission sol 12 (March 2, 2021) the SuperCam instrument atop the rover's mast zapped a rock dubbed Ma'az 30 times from a range of about 3.1 meters. 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. This SuperCam close-up of the Ma'az target region is 6 centimeters (2.3 inches) across. Ma'az means Mars in the Navajo language.
