第8页：火星地表有盐水遭吐槽
NASA最新一次的报告中又称我们在火星取得了重大发现那么就让我们看看NASA的这次发现是否一次很坑爹！下面我们来看看原文是怎么说的。
US satellite observations have produced the first strong evidence for water flowing on Mars.The water is a brine saturated in salts such as perchlorates. As it seeps down the slopes of Martian craters and mountains, it leaves narrow streaks less than five metres wide, which appear and lengthen during the warm season and fade during the Martian winter.Although the salty liquid would not be drinkable by visiting astronauts in its present form, the presence of any water strengthens the idea that Mars may harbour microscopic lifeforms。
“Our quest on Mars has been to ‘follow the water’ in our search for life in the universe, and now we have convincing science that validates what weve long suspected,” said John Grunsfeld, Nasas head of science. “This is a significant development, as it appears to confirm that water, albeit briny, is flowing today on the surface of Mars.
美国卫星观测找到了火星表面存在液态水的首批强有力证据。这种水是含有饱和盐类（如高氯酸盐）的咸水。随着咸水渗入火星陨石坑和山丘的斜坡，它留下了不到5米宽的狭窄条纹，这些条纹在温暖季节显现并延长，而在火星冬季时逐渐消失。虽然这种咸水以目前形态无法被到访火星的宇航员饮用，但任何形式水的存在都会加强火星可能存在微小生命形态的设想。“我们在火星上的探索一直在‘循着水’寻找宇宙中的生命，而现在我们有了令人信服的科学证据来证实我们所长期怀疑的，”美国宇航局(NASA)科学部门主管约翰.格隆菲尔德(John Grunsfeld)说，“这是一项重大发现，因为它似乎证实了如今有水（尽管是咸的）在火星表面流淌。”
从上我们不难看出，我们期待了很久的发现原来只是告诉我们。火星有水！盐水！有没有一种很坑爹的感觉，盐水？我们如何在盐水中生活呢？很显然，大部分人们的认知里盐水无法让生命起源，但是我们必须沿着水的轨迹在太空中进行寻找，或许我们就可以找到那个存在过生命的地球以外的行星。
