This video must be an out-take or something. 9.5 minutes of a pleasantly nerdy NASA geologist wandering among bubbling muddy hot springs in Iceland, ad-libbing about searching for signs of a similar environment in Mars' ancient past. One brief simulation of the Martian surface. Two minutes of interesting material, repeated over and over to fill the remaining 7.5 min.
