You’d be hundreds of thousands or millions of miles from a fully stocked hospital and a surgeon with steady hands. There’s the option of doctor-assisted surgery from Earth — a fellow astronaut performing the surgery with remote assistance from a doctor via video link. But the lengthy communications delay make this a poor option anywhere further than the Moon.
Luckily for our Mars-bound descendants, the European Space Agency has a solution: an information-loaded assisted reality helmet that will let anyone identify and perform minor surgery to repair injuries."
