The possibility of practical artificial "gravity" isn't the only reason that's a stupid argument. We regularly send people to the ISS for longer than it takes to get to Mars and they're fine. Sure, it takes them a few hours to fully re-adapt to gravity and a few months to regain their muscle mass, but they're not sick.

- blhack 10y agoThe trip to mars takes about 6 months (~180 days). Every single record in the table you linked is longer than that.
- gph 10y agoAh, I guess I was assuming round-trip. Article mentioned 3 years as the likely shortest round-trip. I suppose if we are talking about a one-way death trip then yea. Maybe some people will do that initially, but long-term you'd have to think our goal of reaching Mars would include being able to return.
- rch 10y agoTravel to Mars will be significantly different w.r.t. cosmic ray exposure: "Exposures on the ISS average 150 mSv per year, although frequent crew rotations minimize individual risk. Astronauts on Apollo and Skylab missions received on average 1.2 mSv/day and 1.4 mSv/day respectively." https://en.wikipedia.org/wiki/Health_threat_from_cosmic_rays https://en.wikipedia.org/wiki/Health_threat_from_cosmic_rays
