Much shorter and less florid than the original novel, this one tells the story of the survivors' progress on their new world, Bronson Beta, after the destruction of the Earth.

The Americans, under the leadership of scientist Cole Hendron, managed to launch two space Arks, carrying hundreds of people, as well as the animals, plants and knowledge they will need to hopefully survive on the alien planet.

The survivors of Hendron's original, smaller Ark set out to establish a colony, aware (from a road they find) that an alien civilization once existed on Bronson Beta.

Kyto, Tony's Japanese former manservant, finds a piece of blank paper blowing in the wind: watermarked in English, it provides a first clue that another group of survivors have landed on Bronson Beta.

It is revealed later that a group composed of Germans, Russians and Japanese intend to establish a "soviet" called "The Dominion of Asian Realists."

This species built five such cities to survive their world's departure into interstellar space, but ultimately decided to simply become extinct after they were completed.

Once a linguist deciphers the natives' language, it is learned that the five domed cities were named Gorfulu, Khorlu, Strahl, Danot and Wend.

They discover everyone is alive, but drugged; they give the doctor antidotes and then hear an aircraft approaching, occupied by men with Slavic features.

The story ends on an optimistic note with a reference to the first pregnancy among the colonists, Eve and Tony's, and the confirmation that they have passed aphelion and are definitely locked into orbit around the Sun.

However, the box office failure of Conquest of Space set back his career for the remainder of the decade and destroyed any chance of a sequel.
