No fetuses have gestated in low gravity. That sounds like something we could do animal trials on.
But wow, getting a live sheep into space, and fed, and exercised, and cleaned, all for months… that alone is a big undertaking. Just to get a single data point that’s about another species.
I wonder what is known or not know. I’ve read about experiments with lower plants and animals but not what the results were, nor whether we’re ready to try more complex life
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.
