We’ve all read about it: after decades of construction, a shiny new generation ship is loaded with a crew of bright-eyed optimists. Once the sun is just another bright star in the sky, mutiny and civil war reduce the crew to ignorant peasants…unless something worse happens. This is a narrative pattern set as early as Murray Leinster’s 1935 “Proxima Centauri,” solidified by Heinlein’s 1941 “Universe,” and embraced by authors ever since: human foibles in the confined space of a generation ship ensure calamity. Ideally not of the sort that leave everyone too dead to be interesting.
