Hours before NASA's phoenix mission was due to land on Mars, the Naked Scientists took our own tour of the Martian landscape. We discuss how looking in valleys could tell us what shaped the Martian surface, and how probing Martian mud could reveal signs of life past and present. Also, we find out how scientists have watched the explosive death of a star, and how an asteroid collision millions of miles away could have seen the birth of the meteorite that killed off the dinosaurs. Plus, in Kitchen Science, we show you how to make weightless water!
