Guest: Open Lines with Dr. David Livingston. Topics: Nuclear rockets and propulsion, bone loss, radiation, VASIMR. This Open Lines program was a two hour plus discussion without a break regarding many issues ranging from space policy to nuclear propulsion. The VASIMR was again a focal point for discussion and this took us into a lengthy discussion of nuclear propulsion. Nuclear Thermal Rockets were the main topic but other nuclear propulsion concepts were discussed. This seemed to be the overwhelming topic as caller after caller talked about nuclear propulsion as well as radiation.
