Astrobiology is a branch of science that, for now, lacks anything to actually study. Despite this lack of research subjects, however, the search for life beyond Earth has a few rules of thumb. The most important is “follow the water”. The unusual chemical properties of water make it vital for life on Earth. And, since the laws of chemistry are the same everywhere, it is not unreasonable to think that water may play the same role on other planets too.For most of the space age that insight led scientists to Mars. Although the planet is today a frigid desert, there is plenty of evidence that it used to have oceans on its surface like Earth’s. That is one reason why, these days, Mars is lousy with landers, rovers and orbiting probes looking, among other things, for any ice or patches of liquid that may have survived.
