Ion Propulsion for Mars Expedition Spaceship
In 1954 Dr. Ernst Stuhlinger conceived an idea of a Mars expedition using ion propulsion.
A nuclear reactor would drive a turbine to provide electricity that would drive an ion engine using cesium propellant. This idea was shown in Walt a Disney's program broadcast on 4 December 1957. Notice Dr. Stuhlinger was holding a slide rule.
Dr. Ernst Stuhlinger was one of the 126 German scientists brought over to the United States after World War II. He passed away in Huntsville Alabama in 2008 at the age of 94.
