University of Arizona engineers have developed a new system that allows autonomous vehicles to scout out underground habitats for astronauts. On this episode of Here's an Idea™, Wolfgang Fink, Associate Professor of Electrical and Computer engineering at UArizona, discusses how the approach could help address one of NASA’s Space Technology Grand Challenges by helping overcome the limited ability of current technology to safely traverse environments on comets, asteroids, moons, and planetary bodies such as Mars.
