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.

Everything I’ve ever seen about plants indicates that they grow abnormally in zero g. Life is complex and made up of many different chemical processes. All it takes is for gravity to have an effect on one of them and life goes awry. It’s humbling how fragile we are, how narrowly adapted when it comes right down to it. I remember learning that we can’t share most viruses with pets because their bodies are a few degrees of temperature off from ours. I thought wow, viruses are not very robust if they are attuned to living in such a very narrow set of conditions. But honestly we’re no different.
