Atomic Space Propulsion and Power

Flashgordon2014: Interesting article on evolution of propulsion. Clearly, we are going to need nuclear propulsion for deep space travel–solar is not going to cut it. I like the quote from  Konstantin Tsiolkovsky that stated in 1903  “the Earth is the cradle of mankind, but man cannot live in the cradle forever.”

Full scale mockup of the final design NERVA-1 engine circa 1970 that was designed to deliver 75,000 pounds of thrust at 1,500 MW, 10 hours of running lifetime at full power and 60 recycles (full starts and stops) and a specific impulse of 826 seconds.
