美国航宇局最近表示,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。
NASA recently said the courageous Mars rover made one of the most significant discoveries on the surface of Mars: a small piece of Martian soil lifted from the damaged wheels of the rover proved that the environment used to be in the past may be well suited to the survival of microbes. These deposits are produced when spring water or steam meets volcanic rocks.
