Re: Reproduction Away from Earth

I have wondered if humans, insects or some beast of burder will be engineered and grown for the off worlds, to help colonize the future biodomes on Mars, the Moon, Titan or Europa?

Mouse embryos grown in space for first time: Japan researchers

To me this starts to add hope that low gravity situations will not be impossible to cope with.  Mars, and also synthetic gravity machines.

I do not so much favor pregnancy in microgravity.  Vomiting and other bodily functions would make it hard to manage.  But I am starting to think that .2 g or somewhere thereabouts might be workable to some extent.

I think the sensation of up/down will be an important boundary.

Well, this seems to indicate .15 g as the boundary: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4153541/
Quote:

We found that the influence of 1 g in determining the perceptual upright did not depend on whether the acceleration was created by lying on the centrifuge or by normal gravity. The 50% threshold for centrifuge-simulated gravity's ability to influence the perceptual upright was at around 0.15 g, close to the level of moon gravity but much higher than the threshold for detecting linear acceleration along the long axis of the body. This observation may partially explain the instability of moonwalkers but is good news for future missions to Mars.

So, these are good things to try to define.

Done
