How NASA's Search for ET Relies on Advanced AI

The biggest knock against sending robots to explore the solar system for signs of life has always been their inability to make intuitive, even creative decisions as effectively as humans can. Recent advances in artificial intelligence (AI) promise to narrow that gap soon--which is a good thing, because there are no immediate plans to send people to explore Mars's subterranean caves or search for hydrothermal vents below Europa's icy waters. For the foreseeable future those roles will likely be filled by nearly autonomous rovers and submarines that can withstand hostile conditions and conduct important science experiments, even when out of contact with Earth for weeks or even months. When Steve Chien took over NASA's Jet Propulsion Laboratory's Artificial Intelligence (AI) Group in the mid-1990s, such sophisticated AI seemed more like science fiction than something destined to play a crucial role to the success of NASA's upcoming 2020 mission to Mars. Chien had a vision to make the technology an indispensable part of NASA's biggest missions.
