Sir Martin Rees, Astronomer Royal and Professor at Cambridge University in England was the guest on this program. We discussed his new book, "Our Final Hour" and the risks we face as humans at our own hands with our science development, political policies, and behavior. Professor Rees shows how this may prevent us from becoming a space-faring culture. We also talked about how best to become space-faring, the proper roles for both the private and the public sectors in space development, the International Space Station.
