For hazards, I would say: space, the ship (its systems), humans, enemies (Alliance, Reavers, whatever). Space would replace environment, while ship would replace weather (systems failures, etc). Humans replace mice and enemies replace animals.

In terms of skills, I don’t think you’d need to add much. Maybe make Hunter into Gunslinger, and keep Fighter as Fighter (or make it Brawler). For riding, just have Rider instead of Insectrist. Some of the craft-type skills probably need to be removed. Fill those in with necessary skills for the setting, like Engineer, Technician, etc. Harvester becomes Salvager, etc.
