This four-legged explorer prototype combines autonomy "smarts" provided by JPL with a doglike walker called NeBula-SPOT, built by Boston Dynamics. Subterranean Spot was developed in response to the Subterranean Challenge, a contest sponsored by the Defense Advanced Research Projects Agency (DARPA).
This electronic canine was designed to demonstrate the autonomy needed to navigate extreme environments without human guidance or access to GPS.
Mapping caves on the Moon or Mars could identify good shelters for future astronauts. Moreover, if it exists at all, microbial life has a better chance of survival under the surface of Mars or within the icy seas of planetary moons, like Europa, Enceladus and Titan. NASA wants to search for life in
