It turns out that NASA and others have been thinking about the inefficiencies of using chemical rockets to go to the Moon, Mars and the Outer Planets.  One very attractive solution is Nuclear Thermal Propulsion, a technology that was begun in the 1960's and considered as a viable method of propelling Apollo astronauts to the Moon, but was abandoned in favor of chemical rockets.  Fast forward to the twenty first century and we are back thinking about using this promising propulsion to get humans and space probes to the outer solar system quickly.  This podcast is the audio version of a Future in Space Hangout sponsored by the American Astronautical Society.
