Bollocks. People live in Antarctica for months at a time. Airplanes regularly fly cargo longer distances across the Pacific, and move plenty of people, than from Argentina (or NZ) to Antarctica. They walk around, outside, with heavy coats, and don't die after 10 minutes. There are PBS videos on YT about how they manage the sewage and garbage in Antarctica, and you can see the guys walking around outside, hanging out. > NASA has sent people to the moon and back multiple times with 1960s technology NASA has sent people to the moon, who walked, briefly, while in suits to keep them alive on a minute-to-minute basis. If a single thing went wrong they would die. Several folks almost died -- they made a movie about that -- and some actually died (e.g. Challenger, Soviet losses, etc.). > multiple independent entities have sent cargo to the moon in trivial quantities, and where, in most cases, it stayed there. > and there have been people living in orbit on the ISS for a while now If by people you mean < 12 humans at a time, and at what is an insanely high expense compared to keeping someone alive in the Arctic or Antarctic. And most of them have major or permanent changes to their bodies, like vision, loss of bone density, or the myriad issues that the guy -- the one (1) guy, who did it once -- who stayed up for a year. An explanation of those health issues: https://time.com/5568522/kelly-twins-year-in-space/ https://time.com/5568522/kelly-twins-year-in-space/ There is no reason to think we could successfully have kids, mature to adulthood, and function as a human in less than Earth's gravity -- and given the impact of micro-grav on adults it's not crazy to think it would be a big problem. These are exceptional, and incredibly expensive one-offs. Saying we can live on the Moon or Mars based off of that is like saying most humans can be Olympic runners because someone did a sub-2 hour marathon, one time. > but as far as I know there's no technical reason they can't We can't even keep a dozen people alive in the Biodome, and if they didn't open it chances are the ecology would have collapsed or they would have run out of O2 due to the concrete messing with the CO2 & O2 ratios. And when something went wrong they just walked out -- and that ain't happening on the Moon or Mars. At least on the Moon you're a "short" flight away -- not months of solid burn away.
