A book review on the latest Weinersmith creation. It’s true, there is so much we don’t know.

Just throwing this out there on this forum because missing technology is the problem that kills the dream of Mars, according to the authors.

One of the things standing in the way of an"civilization" on Antarctica is that it's illegal to build a civilization on Antarctica. We could absolutely do it, assuming we were willing to fight a war and the resources were worth it

We could absolutely do it

Every exploration into hostile environments heavily relies on goods and services imported from the rest of Earth. Biosphere 2 is as far as I know still the only time we ever tried to actually build a completely independent ecological system, but that was 30 years ago, in a non-hostile environment, only run for a short amount of time, still had tons of problems and would still be missing a lot of stuff to be truly self sustaining for long time periods (e.g. no industrial facilities).

These would be the problems that are currently being worked on prior to manned Mars (and to a lesser extent, lunar) missions.

We absolutely will not be shipping containers of food to Mars. That's absurd.

We absolutely will be. You have no concept of the amount of energy and resources needed to feed a single human being on Earth for one meal, let alone a whole colony on another world without a breathable atmosphere and possibly toxic dirt for an indeterminate time. Farming under the best of conditions is extremely energy consuming, then there's the need to either import hardware from Earth that is specially made for Mars or go old fashion and do a lot of it by hand. There is no where else in the solar system where you can just throw seeds at the ground in large enough quantities and feed whole cities. I do homesteading, my dad tried to be totally self sufficient foodwise when I was a teen. Guess what? Turns out that's really, really hard to do. And that's under the ideal conditions of Earth.

But you didn't have NASA level technology. There is a lot you can do to increase food production using less space if you're willing to pay the upfront and energy costs.
