So far i imagine things as following : instead of spinning up the whole rock, they have a spin station nearby, and build really big structures in microgravity, hangars for ships, factories etc. Due to lack of biosphere, it is common to reprocess dead bodies to food, fergitilizer. Questions : what can be the biggest working hazards there? In microgravity, they have hours before a mine collapses. Maybe overlook some minor damage caused by micrometeors, and a rocket blows up? Is there any suggestion, books that could help imagine everyday life there?
