This comic but informative look at the history of space exploration looks this week at the role that leaps of the imagination have played in the science of rocketry, including the strange story of Russian Cosmism, and how their mission to bring back to life everyone who has ever lived produced pioneering work on multi-stage rockets: and the even stranger story of a plan in the 1950s for a giant spaceship capable of carrying a hundred and fifty people that could have been built using existing technology - Project Orion. There was just one snag - it was to be fuelled by nuclear bombs.
