LIFE IN SPACE

We haven’t conquered space. Not yet. We have sent some 20 men on camping trips to the Moon, and the USA and Russia have sent people to spend restricted lives orbiting the Earth.

All these are marvellous technical and human achievements, but none of them involves living independently in space. The Russians need food and even oxygen sent up from Earth. And they haven’t gone far into space. It is only in fiction, and in space movies, that people spend long periods living more or less normally deep in space.

But in a couple of years this could have changed. There could be settlements in space that would house adventurers leading more or less normal lives.

The picture on this page shows where the settlers would live. It seems like science fiction – but it’s not. It is based on plans produced by hard-headed people: engineers and scientists, headed by Gerard O’Neill of Princeton University, summoned to a conference by NASA. They are space enthusiasts, of course, but they are not dreamers.




The settlement is a gigantic wheel, a tube more than 400ft in a diameter bent into a ring just over a mile across. The wheel spins gently once a minute. It is this gentle rotation that makes this settlement different from the Lunar modules that took man for the first time to any non-terrestrial soil, because the spin produces a force that feels like gravity. Every space trip has shown that the human body needs gravity if it isn’t to deteriorate, and gravity also makes normal activities possible. Nobody would want to live for long in a space settlement where everything – people and equipment and the eggs they were trying to fry – moved weightlessly around.

With gravity, life in space can be based on our experience on Earth. We can have farming and factories and houses and meeting-places that are not designed by guesswork. The need for gravity is one of the reasons for building a space colony, rather than sending settlers to an existing location such as the Moon
