I just finished listening to the Audible narration of the excellent Project Hail Mary [1] book by Andy Weir. It explores quite a few of these issues, including the cosmic radiation one. Highly recommended!<p>[1] <a href="https://www.andyweirauthor.com/books/project-hail-mary" rel="nofollow">https://www.andyweirauthor.com/books/project-hail-mary</a>
The Expanse handles this stuff much better than other shows, as has been noted many times. As entertaining as it is, For All Mankind gets things very wrong in a lot of cases and falls prey to a lot of the 'space tropes' that plague sci-fi. And I certainly don't expect hard sci-fi realism everywhere, but in something like For All Mankind, which is supposed to exist in an alternate timeline but be firmly planted in the real world, it's jarring. When it's in something like the movie Event Horizon I really don't care about realism.
> Because thermal radiation (the heat of the stove that you can feel from a distance, or from the Sun’s rays) becomes the predominant process for heat transfer, one might feel slightly warm if directly exposed to the Sun’s radiation, or slightly cool if shaded from sunlight, where the person’s own body will radiate away heat.<p>Since the body also produces heat, would you even feel cool when shaded? If body heat generation outpaces radiation then I think you'd feel warm. Wikipedia puts the energy radiated out as about 2000kcals per day, or right around a human would produce from metabolism. So I guess it basically balances out.<p><a href="https://en.wikipedia.org/wiki/Black-body_radiation#Human-body_emission" rel="nofollow">https://en.wikipedia.org/wiki/Black-body_radiation#Human-bod...</a>
Reading this, I learned that the 'Exposed To Space' stuff that happens in The Expanse (TV show - I've not read the books) is pretty much spot on.
This article is from 2013, but since 2019, there's been active research in things like latent herpes reactivation, which could have implications for long duration spaceflight.<p><a href="https://www.frontiersin.org/articles/10.3389/fmicb.2019.00016/full" rel="nofollow">https://www.frontiersin.org/articles/10.3389/fmicb.2019.0001...</a>
The big question for a Mars expedition is where between 1G and 0G Mars's .4G is for your body. We really need centrifuges in space to start studying this before it becomes something astronauts are depending on.
This should be tagged 2013.<p>I came here just now thinking it was a new article. I actually found it by way of Google a couple months ago after watching a certain episode of The Expanse.
Make the transit ship spin. Surround the habitable parts with water and other materials. It’s so simple but nobody seems to be aware that these are solved problems.
<i>since two of the three methods of heat transfer (conduction and convection)</i><p>This always drives me nuts. Convection <i>is</i> conduction, just in a fluid. Conduction and radiation are two entirely different physical processes.
