When I wrote The Telescopic Tourist’s Guide to the Moon last year, I wanted to refer, amongst other things, to descriptions of real lunar features in works of science fiction. Surprisingly, I found that many of the most famous Moon stories don’t actually refer to specific locations. Even more surprisingly, one of the few novels that does contain realistic descriptions of lunar geography is one of the earliest – Jules Verne’s Around the Moon, dating from 1870.
The surprise comes because Around the Moon – and its predecessor, From the Earth to the Moon (1865) – are probably best known for the completely unrealistic mode of travel, i.e. by means of a projectile launched from a giant cannon. But when I reread the novels, I was struck by just how scientifically knowledgeable they were – by the standards of their time, at any rate. As well as the physical descriptions of the Moon, Verne gets other subtleties right, too – such as the way things move once they get outside the Earth’s atmosphere (something Hollywood barely understands to this day).
So I thought I’d write another little book describing all the science Verne got right – and of course the science he got wrong, too. Here’s the blurb:
The idea of using a large gun to send humans into space is as impossible today as it was a century and a half ago, when Jules Verne wrote From the Earth to the Moon and Around the Moon. Yet he went to great lengths to persuade readers it wasn’t impossible – not through arm-waving and made-up technobabble, but using real physics and astronomy. No one had done anything like that in fiction before – and even today it’s unusual to see so much “real science” discussed in a work of science fiction. But just how much did Verne get right, and what did he get wrong? This book takes a closer look at the science content of his two great Moon novels – from Newton’s laws of motion and the conservation of energy to CO2 scrubbing, retro-rockets and the lifeless grey landscape of the Moon.
