== Clifford D. Simak's version == 

 In the 1950s, Clifford D. Simak wrote a book about the overheating of the sun, and how the Earth would soon be overheated as well.    Volcanoes would erupt, and the oceans would boil away.   Leaders of the Earth argued about having to abandon the Earth, and travel to Mars, but the real problem was getting there.  Somehow.    Thousands of experimental craft were engineered for scratch, and used as "arks" for going to Mars.    The main page of this article would be improved if there were reference to Clifford D. Simak's book being inspired by "When Worlds Collide."   Except I don't remember the name of the book.   This is the one where the requirements of safety were thrown out the window.    Many of the ships that lifted off, had faulty wiring, for instance.   (Other ships lacked functioning air tanks and oxygen regulators.)   Can anybody remember which book it was?
