Nasa-JPL snake robot explores extreme terrain
Nasa's Jet Propulsion Laboratory is developing an exobiology extant life surveyor (EELS). It was conceived to explore diverse terrains and ultimately search for evidence of life.
It was tested in Canada's Athabasca glacier and Mount Meager volcano. The latter expedition was made possible by the Trebek Initiative, a partnership between the Royal Canadian Geographical Society and National Geographic.
