generation ship n.	1955 E. C. Tubb Star Ship in New Worlds Science Fiction June 125 ‘What I can’t understand is why, if the Builders had perfected suspended animation, they had to have personnel at all. Why not staff the Ship with men and women in deep-freeze, send off the Ship, and let them waken when they had arrived?’ ‘First, there are two ways by which men can reach the stars. One is by suspended animation as you have suggested, the other is by generation ship, which this is. We have combined both and so avoided the weaknesses inherent in either. The generation ship depends on new blood replacing the old, but the danger is that the new blood will forget what it should remember. Sixteen generations is a long time, Jay. Even with continual use of educational tapes it is still hard for some people to accept the fact that the Ship is nothing but a metal can drifting in the void. To them the Ship is the universe and they just can’t imagine anything possibly being bigger. The Deep-freeze method is just as bad. Then the personnel have to rely wholly on automatic machinery, even as we do, but they are far more vulnerable than a generation ship could ever be. And there is another thing. We still aren’t certain that they will be fertile after deep-freeze. The animals are, the men and women should be, but no one has ever rested in suspended animation for more than three hundred years before. It was a chance we dared not take.’
