突破之一:火星上曾经历过水环境美国“勇气”号和“机遇”号火星车2004年对火星的探测,是首次在地球之外的另一颗行星上进行真正野外地质勘察。“机遇”号飞行器在对其着陆地点附近裸露岩层的探测显示,岩层中的岩石过去可能曾“浸泡”在液态水中,水流不仅改变了岩石的纹理,而且也改变了其化学构成。2004年12月初,“勇气”号飞行器还在一个名为“哥伦比亚”的地区发现了针铁矿,这一发现是迄今为止火星上有水的最有力证据。科学家称,只有在存在水的情况下才能形成针铁矿。现在,科学家们可以确定地说,火星曾经历水环境。
One of the breakthroughs: Mars has experienced water environment The Mars Rover of the United States “Courage” and “Opportunity” on Mars in 2004 was the first time a true field geological survey was performed on another planet outside the Earth. The exploration of the exposed rock formation near the landing site of the Opportunity Opportunity revealed that the rock in the rock may have been “soaked” in liquid water. The water flow not only changed the texture of the rock, but also changed its chemical composition. In early December 2004, the “Courage” aircraft also found goethite in an area known as “Columbia.” This discovery is by far the most powerful evidence of water on Mars. According to scientists, goethite can be formed only in the presence of water. Now scientists can say with certainty that Mars has experienced water environment.
