To the Ends of the Earth
Cave Man Space Man
S2 • E6 Apr 6, 1998
Under the mountains of New Mexico lies a dangerous cave system where scientists hope to find chemical life forms -- and thereby to discover more about the possibility of life on Mars. An international expedition, including Our Man from the Natural History Museum, braves sulfurous winds to enter this fragile and hazardous ecosystem -- from which it once took 250 people four days to extract a caver with a broken leg.
