美國國家航空暨太空總署(NASA)的 「毅力號」(Perseverance)漫遊探測器在火星的任務帶來了一個重要時刻。

This is the sound of Nasa’s Perseverance rover hard at work on the surface of the Red Planet. It landed on Mars 15 months ago. Since then, it’s been on the move, trundling more than seven miles across the dry and dusty terrain.

這是美國國家航空航天局的 「毅力號」 漫遊探測器在火星表面努力工作時的聲音,它在15個月前登陸火星,自那以後,它分秒必爭地進行探測任務,已經在乾燥多塵的地表上行駛了七英里多。

Now it’s reached its target: a delta where a river once flowed into a huge lake billions of years ago. Scientists think the sediments there could contain signs of ancient life, possibly microbes that once lived in the Martian waters.

現在它到達了目的地:一個三角洲,數十億年前一條河流曾在這裡流入一個大湖,科學家認為,那裡的沉積物可能含有古代生命的跡象,有可能是曾經生活在火星水域的微生物。

The rover will climb up the front of the delta and search for the most promising rocks, drilling into them to collect samples. And some of these could be heading back to Earth – a future mission is currently being planned to retrieve them.

探測器將爬上三角洲的前端,尋找可能與微生物有過接觸或被微生物改變的岩石,在它們上面鑽孔收集樣本。「毅力號」 採集的一些樣本可能會被送到地球,目前正在計畫一個未來的任務將樣本一一取回。
