Space medicine and fatigue
NASA's Human Research Program groups the hazards of spaceflight into five: space radiation, isolation and confinement, distance from Earth, gravity fields and hostile or closed environments. Distance matters most for medicine, because a Mars crew cannot be evacuated and will have long communication delays.
Many of these problems have Earth versions. Remote mine camps, ships and Antarctic stations deal with isolation, delayed evacuation and limited supplies. Fatigue from long rotations and night shifts is a known contributor to errors, so schedules, sleep conditions and fatigue checks are part of medical work.
Medical devices are regulated. FDA classifies devices into Class I, II and III by risk, with Class III, like implanted life-support devices, facing the most review. A medic needs to know their equipment, keep it maintained and stay within its intended use.
The skills that matter in space medicine are the same ones that matter at a remote site: solid basics, improvising with limited gear, clear records and knowing when to call for help.
