Guest: Dr. James A. Dewar. Dr. James Dewar returned to The Space Show to explain and discuss nuclear rockets and what they would mean for space and economic development were they to be used to obtain low cost space access. Dr. Dewar began our discussion with a good explanation of how a nuclear rocket engine works and the advantages such an engine provides in terms of specific impulse. An engine with a higher specific impulse means a significantly larger payload can be brought to space faster than if the engine had a lower specific impulse.
