Among the instruments fitted to the Perseverance rover is a high-precision laser called Sherloc, which will be used to decipher the chemical composition of rocks and determine if they might contain organic materials that indicate life once existed - or still exists - on Mars.
在“毅力号”探测器上安装的仪器中，有一台名为 Sherloc 的高精度激光发射器，它将用来破译火星岩石的化学成分，并确定它们是否含有可以表明火星上曾经存在或仍然存在生命的有机物质。
