Before anyone comments - obviously, we don't have any experimental data. But do perhaps we have ISS or other data that can be extrapolated from?

What I'm asking specifically is, what do we currently know about the development of, for example, a fertilized chicken egg in Mars g? For the purposes of this question, assume that we've handled any radiation problems...

  • $\begingroup$ We have very little data on low-gravity situations. All our data is at 0 or 1 G. E.g. it's not clear that health problems are proportional to gravity. $\endgroup$ – Hobbes Jan 12 '17 at 8:27

    $\begingroup$ There is some data at more than 1 G. Some generations of laboratory mice were raised in a centrifuge on earth under some G. There were some experiments with a centrifuge in a satellite, see page 19 of iaaweb.org/iaa/Scientific%20Activity/Study%20Groups/… $\endgroup$ – Uwe Jan 12 '17 at 13:49
  • $\begingroup$ I don't know how the centrifuge approach escaped me. So you could place an egg in a centrifuge on the ISS and simulate Mars g. $\endgroup$ – Chris B. Behrens Jan 12 '17 at 15:02
  • $\begingroup$ Not only eggs but also different small mammals, even for some generations. But such a rotating centrifuge would not be perfectly balanced and would disturb the microgravity environment of the ISS by vibrations. $\endgroup$ – Uwe Jan 12 '17 at 15:18
  • $\begingroup$ Probably doesn't need to be perfectly balanced to get good data. And I would say that an experiment like this is the raison d'etre of the ISS. $\endgroup$ – Chris B. Behrens Jan 12 '17 at 15:48
