Space nerds, has SpaceX talked publicly at all about the en-route obstacles to a Mars mission (radiation, deconditioning, closed-loop life support) and how it plans to address them? I can find stuff about launch and landing but not the middle part that is the actual dealbreaker.

I’m sure you’ll ignore this, but: For a transit time of 3-4 months, that’s a solved problem. The Russians had a >400 day mission and the dude who did it walked after landing on Earth. That’s 3 times the gravity of Mars and 4 times the duration of Mars transit on Starship.

Although most astronauts in Earth orbit are still protected to some degree by the magnetosphere. Travelling to Mars will leave that protection completely and then on Mars, you will have similar problems even if a bit less pronounced (less gravity, no Mars magnetosphere).

Ah, if you only consider transit time, I agree with
@Robotbeat, this is probably mostly solved (or at least known with workarounds). We had people on space stations for comparable periods of time. But on Mars, those problems don't go away entirely, expect long term medical issuesThanks. Twitter will use this to make your timeline better. UndoUndo

you must not be familiar with the conditioning findings. 3 months is the length you can take before symptoms of 0g mass loss pop up.
