Experiments have begun to alter human cells in the lab. Can they be made radiation-proof? Can they be rejiggered to produce their own vitamins and amino acids?

Creating astronauts able to make their own essential nutrients would obviously be immensely complicated. Yet as complex as it is, it might be less challenging than the alternatives, such as terraforming a planet or bringing along a space ring complete with an atmosphere, plants, and livestock grazing overhead.
