在火星上,有一個看起來像化石烏龜的石頭!其實這不是化石,而是一塊大約15米長的岩石。這塊岩石叫做Miraflores,是NASA的好奇號探測器在火星的4922個火星日中看到的。這個小山如果能保存下來,可能是因為它比周圍的石頭更能耐受風吹雨打。現在,最近的風把它的上面覆蓋上了橘色的火星沙。在它頂部的下面,可以看到很多層層分明的岩石,這可能意味著長時間以來,風把沙子吹過來,然後被地下水硬化。地球上也有類似的風腐蝕岩石,比如中國的凱達姆沙漠中的yardangs。好奇號和它的夥伴探測器毅力號繼續探索火星的悠久歷史,並尋找早期生命的跡象。
原文:
Is this a fossilized turtle on Mars? No. Although resembling a large Earth tortoise, this is a layered rock outcrop on Mars that is estimated to span about 15 meters, making it much larger than turtles on Earth. NASA’s robotic Curiosity rover came across this unusual mound, dubbed Miraflores, last month during its 4922nd Martian day exploring Mars. The small butte may survive because it was somehow more resistant to erosion than surrounding rock. More recent wind has now covered its top with orange Martian sand. Below the top shell, many layers of stratified rock are visible, possibly indicating a long history of intermittent wind-blown sand being deposited and then hardened by ground water. Similar wind-eroded layered landforms, such as yardangs in the Qaidam Desert of China, exist here on Earth. Curiosity and its companion rover Perseverance continue to investigate the ancient history of Mars as well as searching for signs of primeval life.
