据国外媒体报道,美国宇航局表示,“勇气”号火星探测器在火星表面有了一个最重大的发现:这辆火星车破损的车轮所掀开的一小片火星泥土,证明过去这里的环境可能非常适合微生物生存。这些沉积物是在温泉水或蒸汽遇到火山岩时产生的。火星漫游者的首席科学家史蒂夫·斯库里斯表示,在地球上,这些地方一般都是细菌聚集的场所。他在美国地球物理学联合会会议上说:“我们对这项发现感到非常激动。” According to foreign media reports, NASA said that the Courage Mars rover has one of the most significant discoveries on the surface of Mars: a small piece of Martian soil lifted from the damaged wheel of the rover proves that the past Environment may be very suitable for microbial survival. These deposits are produced when spring water or steam meets volcanic rocks. Steve Skuris, Mars rover’s chief scientist, said these places are generally bacteria sites on Earth. At the meeting of the American Geophysical Union, he said: “We are very excited about this discovery.”
