    How can they say it’s permanent when it was only 6 months of data and the astronaut is still alive?

      Probably the same way we can know things like if you break a glass, it’s gonna stay broken. Or if you cut off a finger that it stays cut off.

      Probably seen telomere damage from radiation or some such. Some sort of thing which doesn’t grow back naturally. So sans technology that will change our biology, we know some things are permanent.

      Although like 20 years ago I could’ve used a tooth falling off as an example, but I first read about tooth regrowing studies in a science mag in the early 00’s and 20 years later we’re kinda there actually. The researchers hope to have it for general use by 2030. A tooth regrowing drug! Phase-1 human trials already concluded without adverse effects.

    Permanent changes means no epigenetics. So probably mostly radiation? Probably teaches us to improve radiation shielding. Which is pretty simple, just put the water storage on the inside around the hull.

      I’m no scientist, but wouldn’t that mean the water becomes irradiated and when the astronauts drink it they’ll still be getting approximately the same level of radiation they already are?

        Negative, it only gets irradiated if the water comes in contact and gets contaminated with radioactive material. Just like the cooling water that flows out of a nuclear power station is not more radioactive than the water that goes in.

          Actually it technically does get irradiated by neutron activation, but the half life of Nitrogen-16 is only 7 seconds, so by the time it reaches the filters it’s already poof decayed away. (Very small amounts)
