摘要

在极度干旱的环境中,生命可以通过从大气中汲取水分的盐类获得水。因此,这些盐类应该成为寻找火星生命的重点。美国宇航局 "海盗 "号着陆器所做的实验,可能因为加入了过多的水而意外地扼杀了火星生命。

We may be looking for Martian life in the wrong place
In hyperarid environments, life can obtain water through salts that draw moisture from the atmosphere. These salts, then, should be a focus of searches for life on Mars. The experiments performed by NASA’s Viking landers may have accidentally killed Martian life by applying too much water.
