Until we do know, then we should simply use what we already know actually works. That is the wisest choice. <br /><br />You left out child development. We already have encountered the darndest sensitivities of pregnancy to various things, and we also already know that developing children are at least as sensitive to various exposures. <br /><br />Now maybe animal studies can resolve some of these things quickly, and maybe not. Many animal models fail us, as this simulation is disease-specific. They can give you confidence, but never certainty. That is something to remember. <br /><br />For now, I simply suggested in the article that we rely on where people have successfully lived and reproduced for millennia: in 20.946% oxygenated air, at altitudes as high as 13,000, even 15,000 feet. We can always adjust later, as better data come to light with experience. <br /><br />As for "hypothetical" dangers, if something about the habitation atmosphere damages the health or lives of pregnant women and young children, it is too late to go back and "fix the problem" for them. That is the fundamental problem with the "unknown danger" situation, where the threat may or may not be real. That's the point: you don't know if it is real. <br /> <br />If you choose wrong, then you have done evil that you cannot undo. That is why it is better to do only those things that you already know work, whenever possible. The choice is really ethical, not scientific. <br /><br />-- GWGary Johnsonhttps://www.blogger.com/profile/06723964751681093047noreply@blogger.comtag:blogger.com,1999:blog-2675974463524895416.post-38606558153814702692018-03-23T18:07:59.540-05:002018-03-23T18:07:59.540-05:00you present a straightforward and immediately acti...you present a straightforward and immediately actionable analysis on suit and hab pressures, but at the end you go off the rails with speculation about possible effects on pregnant women. this is the sort of question that could easily be answered with animal testing on earth.<br /><br />"just deal with it" is not a useful suggestion when you have to leave the habitat or colony in an emergency. real, known dangers such as decompression sickness ought to outweigh imaginary hypothetical dangers.fennhttps://www.blogger.com/profile/06017675004076463594noreply@blogger.com
