Look at where NASA sends its missions and one world stands out: Mars.Why? Mars may hold The Big Discovery - alien life (however humble). But what if Mars isn't, after all, the best place to look?The dwarf planet Ceres, in the asteroid belt, has had the ingredients of life - liquid water and carbon chemistry - near its surface geologically recently*. It's gravity is far lower than Mars, a major advantage if you want to collect samples from it, nor does it have Mars´ deadly weather. Perhaps its time for a lander to Ceres...*So not at all recently, but not so mind buggeringly long ago as a lot of the things in the universe.
