Space Station Crew Drinks Recycled Urine

An anonymous reader writes "After the astronauts on the International Space Station finished up their communications with Space Shuttle Atlantis yesterday, the crew on the Space Station did something that no other astronaut has ever done before — drank recycled urine and sweat. The previous shuttle crew that recently returned to Earth brought back samples of the recycled water to make sure it was safe to drink, and all tests came back fine. So on Wednesday, the crew took their recycled urine and said 'cheers' together and toasted the researches and scientists that made the Urine Recycler possible. After drinking the water, they said the taste was great! They also said the water came with labels on it that said 'drink this when real water is over 200 miles away.'"

Nonsense.

Everyone drinks recycled urine and sweat every day.

Hell, your sewage is merely treated and released back into the environment.

And by "released back into the environment" what you actually mean is "pumped back into the river". Oh sure, it's "treated", but it's still not REALLY safe to put back in there. So what do we do? We take some water out of the river, make it safe to drink, take a shit in it, then make it kind of safe, then dump it back into the river... so that the next town can pump our shitwater out of the river, and repeat the whole process.

Humans actually have one of the weakest immune systems out there, mostly because we've been breeding less and less for hardiness (and worse, in the past ~400 years less for intelligence as well) thanks to the "contributions" of the few bright sparks who come up with things like, say, "the crapper" and make it so that those with downright piss-poor immune systems pass them on to the next generation.

This needs slapping with a massive [citation needed]. A mere 400 years is not enough time for significant evolutionary changes. Most animals don't foul their own nests either. Ones that have fixed nests just go a distance away from them and ones that don't just move on afterwards. A toilet just allows us to move our waste away from ourselves easily, rather than moving ourselves away from our waste. It's also worth noting that proper sanitation is not available to a large chunk of the human race (who have not, therefore, had this lack of evolutionary pressure away from developing a strong immune system) and that the average lifespan of these people is around half that of people who do.

Not to mention the fact that in a number of cases the operation saves the mother; the child was not at risk. The child would have survived anyway, and would have passed on these genes whether the operation took place or not.

For the draft to have had an impact on the gene pool, a vast majority of the people who went to war would either have had to be killed or mutilated in a way that rendered them unable to reproduce. Even in the American Civil War, that was not the case.

Can you find me even one example of a war that actually affected the reproductive ability of all of the soldiers that fought in it?

Also, lets not forget that the draft only affects men. Women were excluded, and therefore any gene not on the Y chromosome would have been excluded from being affected.

Re:Nonsense.

[geekoid]

In humans? no it's not enough time for anybig changes.

Your example involves selective breeding by an ;outside' source, us.

But in the natural environments, 400 years just isn't a long time.

We are not, or have been the decedents of the big brave people that went to battle, we are the decedents of the little shit that stayed in the cave and fucked all the women.

Your look is way to myopic. I could say all the people smart enough to avoind the draft and stayed home helped the gene pool, but that to is too myopic.
How many people where drafted? what percentage died before having off spring?
Add to the fact after WWII the ones that did survive fucked like rabbits. So the physically able went to war, and the survivors came back an had kids. Wouldn't that be an evolutionary improvement?

Living in a desert

[mc1138]

While it may not seem like it the space station is essentially a desert with very little water. This sort of situation really makes it important to loose as little water as possible, and as the astronauts even said when properly treated it tastes great!

If it's 2 hydrogen bonded to 1 oxygen in the right form it's "real water" Honestly, the Astronauts should be some that would not have the silly reaction to drinking treated water.

Certainly, but 2 hydrogen bonded to 1 oxygen exists in ripe form in your toilet as well, it's more a question of the additives. And if we did NOT feel an instinctive revulsion towards our own excrement, we would have been wiped out as a species a long time ago after eating our own toxic feces (that rhymes, too). So give those space monkey a break, eh?

If someone takes a piss in the vat at the Coca-Cola plant, it's still "real Coca-Cola" to a high empirical degree, but I think you'd still appreciate the psychological distinction between that Coca-Cola and the stuff that came out beforehand. Likewise there's a strong innate (unlearned) notion of contamination in humans that makes this "purified urine" rather than "ever so slightly contaminated water" from the astronauts' perspective.

I'd like to see some evidence for that.

If you you have little kids, or have spent any time with them, you'd know that they'll happily put anything in their mouths if you don't stop them. The idea of contamination is deliberately taught to children, using words like "icky," "yucky," and "ohmigodwhatisthatinyourhand."

Big deal! we all do

[petes_PoV]

Water abstracted from rivers that are fed from treatment plants. That contains water from recycled urine. As does rainwater, when urine evapourates into clouds, which then condense into rainfall.

Sadly this story has all the self conscious immaturity you'd expect from a 12 year-old, sniggering because it's about pee. Whatever happened to the grown-ups section of Slashdot?

What does Budweiser have to do with the ISS?

Re:How does that make it not "real water"?

[geekoid]

Wow, you are really mistaken. The tastes of the water going into the mix is heavily controlled for taste. Even to the point where some plants have there won water treatment system on top of a cities water treatment system.
So like most people on /, while technically true, not practically an issue.
Save fountain drinks; which really to heavily on the min. wage worker remembering to check the mix.

"You should count yourself lucky if you've ever had two servings of Coca-Cola that tasted the same."
That is just stupid. even if what you said was true to a high degree of practicality, most people drink coke from the same location. It's not like every can in an 8 pack came from a different part of the world.
