We did a lot of animal experiments, but none of them explored things like wounds and healing. 0G on aircraft doesn't last long enough, and the Vomit Comet is expensive, anyway. No, I suspect spatial orientation doesn't really matter as long as the doctor is properly trained. We're looking at purely physiological processes there, what the patient perceives is another matter. Flying to Mars would take a little less than a year, even using Hohmann transfer. Given how long we've spent in lockdown, it shouldn't be too hard to find people who are comfortable with those conditions.  |

If it take about a little less then a year, then NASA, Space X and anyone else who plan to go to Mars are not ready then. A little less then a year is enough time to have a medical emergency. With us not knowing the minimum gravity needed to perform a medical procedure. I see us having little clue what the requirement for our artificial gravity device would be. Which is the first thing the engineering staff will ask you before they start on the artificial gravity device. |

Which is the first thing the engineering staff will ask you before they start on the artificial gravity device. Whoever goes on the first trip will be very, very fit. Most Nasa astronauts are USA Navy or Airforce in background, and then all receive extensive further physical training. SpaceX isn't likely to slouch when cherry picking crew for the first Mars launch either. "Building" artificial gravity isn't so difficult, you just spin the craft long ways end over end, or if you have two craft you tether them together and do the same thing. To get off the ground at all the craft already fundamentally must sustain greatly in excess on 1G on it's longest axis. Knowing exactly the minimum isn't so important on the first occurrence if you can make 1G, we do all our medical procedures on the ground at 1G anyway. |

Fitness isn't going to be enough for what would be, in effect, a two-year trip. You're going to be prepared for accidents, and without the means to rapidly return to Earth, that's going to mean developing first aid procedures. This means either a centrifuge or researching dedicated 0G procedures, which may come with unknown complications.
If you spin a ship along its axis, it's not sustaining +1G, as in on launch, but -1G. It's being pulled apart, not compressed, and this is a different kind of stress. So, unless you build a Hail Mary-style contraption with winches and ropes (and that doesn't do well under thrust, so you need short burn periods), the ship will have to built sufficiently strong both ways. That said, on a trip to Mars, you'd be better off simulating Martian gravity, which is less demanding than 1G.

Being very, very fit does not make anyone immune to a medical emergency. And last I checked Both the moon and Mars has less then 1g. Which makes me ask could we do medical procedure on the Moon or Mars? |

So how do we know if our doctor is properly trained to do a medical procedure in 0g? |
