This is what the novel 'The Future Happens Twice' is about: A super-secret government agency has been given the responsibility of saving mankind by sending a starship to a planet 42,000 years away with 5,000 frozen embryos, 2 androids, and a crew of four children who are artificially born 18 years before the landing, raised and trained by the androids. This seems straight forward enough; however, its complexity is greatly increased by the moral questions of cloning and lying to test subjects.
