About the 1974 sci-fi novel The Dream Millenium by James White.

--1974. A technological step further than Heinlein's Universe is The Dream Millennium, by the Irish writer James White. Until we can travel faster than light, how can we successfully complete a journey to the distant stars? White's spaceship crew, male and female, were in a sort of "frozen sleep," during which they dreamed of the problems that made them leave earth; by arrival time at a habitable world they had worked them out, and could make a fresh start mentally as well as physically.
