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.
Cosmic ray radiation levels in low earth orbit are 2-4x lower than in a Mars transit, and a Mars transit would take six months, not 3-4.

Wrong. The trip time is a function of the rocket architecture, you know the part you think is just the fun part that isn’t the REAL issue. ;) SpaceX’s ITS/BFR/Starship would take as few as 80 days to transit, depending on the year. https://www.spacex.com/media/making_life_multiplanetary_2016.pdf …pic.twitter.com/oiAIp3EIus

I go by the NASA design reference architecture because Musk has a very long history of making shit up.
