M3 Variant

M3 Variant was a rocket fuel developed by the British Rocket Group for use on the Mars Probe missions. However, it was deemed unsafe for use due to it producing excessive G-Force. This did not deter the Third Doctor from using it to rescue the astronauts from Mars Probe 6 and Mars Probe 7. (TV: The Ambassadors of Death)

M3 variant was later used by NASA to launch Apollo 23. (PROSE: Apollo 23)

Pure M3 Variant was combined with cherry brandy and pure crème de bananas to create the alcoholic cocktail Kronka. (PROSE: The Highest Science)
