Aurora was published by Orbit in 2015. A generation ship carrying two thousand people has traveled for 170 years to the Tau Ceti system. The ship’s AI narrates much of the novel — learning to tell stories, developing consciousness, becoming perhaps the book’s most sympathetic character.
The colonists arrive at Aurora, a moon in the habitable zone. It appears suitable. They land. Within weeks, people begin dying — an alien prion-like organism, too small to have been detected from orbit, is lethal to human biology. The colony fails. The survivors split: some want to continue to another star; most want to go home to Earth.
Robinson wrote Aurora as a deliberate refutation of the “backup Earth” argument — the idea that interstellar colonization is humanity’s destiny and insurance policy. His thesis: planets are complex ecosystems evolved over billions of years; you cannot simply transplant terrestrial life onto them. The generation ship itself degenerates over the return journey — ecosystems break down, metals fatigue, political cohesion dissolves. Robinson’s conclusion: there is no Planet B. Earth is it.
