I know who I think is right.
First point, wrt the impossibility of operating machines on Mars. The Perseverance rover has been operating for over 5 years. Curiosity has been operating for 13 years, far beyond it's intended life.
Second point, wrt the impossibility of being outside of earth's atmosphere for a long period. The current record spaceflight duration is 437 days. The Boeing Starliner's crew was stuck on the space station for 286 days, waiting for a more reliable Dragon craft to pick them up. Back during the cold war, we were taught food in metal cans was safe to eat, because the can itself would shield the food from alpha and beta particles, while gamma radiation would go through the can and out the other side.
I stopped watching his routine at that point.
