Let’s not send a few thousand people to Mars as a big experiment in survival.

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.

      The most not caveat is we don’t know how much gravity is how necessary. We know that microgravity in orbit is too little and not really sustainable. Is gravity on the moon enough more for long term health? Is that on Mars? That’s just two of the questions we can’t know until we get there

      So you build spinning space stations instead of settlements on the martian or lunar surface. Likely close to the same material cost, if not cheaper, while allowing us to actually choose the amount of gravity to generate. We don’t know if martian or lunar gravity would even be sufficient to avoid negative health affects.

        Do those count for gravity ? Are there other downsides that we haven’t even thought of? Many unknowns.
