After a global nuclear war, people colonize Mars, Venus and asteroids



John Wyndham : writer
"(...)exploration of the solar system, with space stations in Earth orbit, then moon bases, and landings on Mars in 2094, Venus in 2144, and the asteroids. This is told through the Troon family, several members of which play an important part in the exploration of space, since they all feel "the outward urge", the desire to travel further into space"
