Space Station Crew Drinks Recycled Urine 349

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.'"

      While a good point, this may not be quite as true in the case of the astronauts aboard ISS.

      A large portion of the water delivered to ISS comes from the Space Shuttle as it combusts liquid hydrogen to power itself while docked. Depending on the source of the liquid hydrogen and oxygen fuel (i.e. Is it generated from electrolysis of water? Condensed directly from the atmosphere? etc), it's possible a significant portion of their water supply has never been urine or sweat before.

      And even if the liquid hydrogen and oxygen was water previously, do water molecules generated from hydrogen combustion really count as "recycled"?

        Regardless, the filtering process is more than adequate to make the water safe. The fact that astronauts tend to be scientists of at least a reasonable caliber, they'll no doubt understand the science behind it and have no trouble drinking it.

        I worked with water filtration in the past and, while I might hesitate slightly on my first sip, I'd have no issue drinking it. I'd bet it's significantly cleaner than most water flowing through pipes on earth.

      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).

      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."

          I think it's still an open question as to whether disgust is innate, but once a child it, the idea of a disgusting object "contaminating" another is obtained more or less immediately. That's not something we teach kids particularly early, and it's actually a rather abstract notion. I don't have access to sociology journals from here unfortunately and it's been a while since I read much about it, so things could've moved on.

          Which is ironic when you consider that parents frequently have to overcome previously decided upon levels of contamination to function as a parent. To use myself as an example, during my wife's first pregnancy test, my job was to hold the filled urine cup and dip the test strip in. I didn't even have to touch the urine, but the thought of it being in a cup so close to me made me nauseous.

          Now, after being a parent to two boys, I can eat lunch, stop to change a poop-filled diaper, and then resume eating lunch (after washing my hands of course!). The idea of changing a poop-filled diaper or wiping the bottom of a young child does not make me nauseous at all. Sometimes I'll forget the different parent-nonparent revulsion levels and tell stories that are perfectly ok by parent standards but make non-parents run to the nearest bathroom to hurl. This can be useful if your coworker brought in something that you'd like. "Hey, that's a nice pudding cup... Though it kind of reminds me of my son's diaper yesterday. I opened it up and stuff just spilled out everywhere and... what's that? You don't feel like pudding anymore? I guess I can eat it."

          Just don't ask to hear my mustard story!

        There is no such thing as "real Coca-Cola". Or if there is, the majority of what goes for "Coca-Cola" isn't "real Coca-Cola".

        Coca-Cola is created from concentrate or syrup. This concentrate is shipped to bottlers who add their own sweetners and other additives, which causes local variations. Then it is combined with water from different sources, causing even more variations. Coca-Cola, even in a can or bottle, tastes differently all over the place.

        Then add to that the abomination that is fountain-based Coca-Cola, which is syrup mixed with carbonated tap water. This means that the Coca-Cola from your local city-water-fed McDonald's tastes differently from the Coca-Cola served in the well-water-fed McDonald's just out of town.

        You should count yourself lucky if you've ever had two servings of Coca-Cola that tasted the same.

        • 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.

          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.

      Is there a "wrong form" for 2 hydrogen bonded to 1 oxygen? I mean, unless you are adding more elements into the mix, I'm pretty sure that as a discrete molecule, 2 hydrogen and one oxygen bonded together is always water. And, afaik, it always happens the same way.... at an angle of about 104 degrees, if I remember correctly.

        Humidity must be a problem on space stations; people lose water due to respiration, let alone perspiration. Presumably there is somewhere a dehumidifier. Perhaps the atmosphere recycler does that job? Hmm, no, looks like there's purpose-built modules.

    If you thoroughly remove these other ingredients it's not really appropriate to call it "recycled urine/sweat" because it no longer contains the chemicals that make it those things. It would be like taking some kool-aid, boiling it, extracting the steam and calling it recycled kool-aid or de-kool-aided-water.
