There haven’t been any medical emergencies in space so far, mainly because missions were short through most of the space program’s history. First aid on the ISS is supervised by doctors at mission control, and if someone were to be injured, they can be evacuated by Soyuz (although it isn’t easy). But going to Mars would take about three years, and with a full crew, the odds are that someone will eventually sustain an injury that requires surgery. There would be no help outside the ship. And surgery in space presents unique challenges that doctors with gravity on their side don’t have to consider. NASA flight surgeon Anil Menon gives us a rundown on the particulars of space medicine.
