The question of robots versus humans as explorers and colonizers of space seems to come up more often these days. The Planetary Society recently posted a podcast of a discussion at the American Astronomical Society's division for Planetary Sciences on the rule of humans vs. robot in space exploration. Among the participants are Buzz Aldrin, Jim Bell, Louis Friedman of the Planetary Society, and Chris McKay of NASA. The subject of science vs. exploration is also covered in the brief podcast. We last covered the robots vs. humans debate in our August story about James van Allen.
