Eating in Space 185

Posted by CmdrTaco from the tang-makes-me-ill dept.
Roland Piquepaille writes "What do you think astronauts aboard the International Space Station (ISS) ate for Thanksgiving? Roasted turkey? Wrong answer. In "Orbital Thanksgiving," NASA tells us they had tortillas and gives details about food in space. If the dining view, 200 miles over the Earth, is great, preparing meals is quite a challenge. For example, there is no refrigerator or freezer aboard the Station, so food must remain good for long periods at room temperature. And you need to avoid crumbs which could float around. This is why tortillas are favored over bread. This overview contains additional references and includes a picture of a cosmonaut preparing food in the ISS galley."

      Temperature is the mean kinetic energy of particles per volume. Space is quite empty, which keeps the temperature quite low. But, do you know what the best (heat-) insulator is? Vacuum.

      What one usually calls "cold" is not something of low temperature, but something with a lower temperature and a good heat conductance. Hence, a piece of metal of room temperature is cold.

        In space, an object will lose most of it's internal kinetic energy by radiation; it emits electromagentic (EM) radiation in relation to it's absolute temperature. Normally, in warm surroundings, the EM lost is balanced by EM receieved from surrounding objects - so when equilibrium is achieved, the temprature of the object stabilises (assuming no other sources of heat energy).

        But, do you know what the best (heat-) insulator is? Vacuum.
        No... Conduction is one loss mechanism. There will be little conduction in space. Radiation however is a very significant mechanism too. Check your thermos flask - it's silvered as well as presenting a vacuum barrier.

        In space, there is much lower background EM depending on whether you are in sight of the sun or not, so for best effect put your "freezer" out behind the ISS away from the sun and I think you'll find that stuff freezes pretty quickly.

      Temperature control is actually quite a problem so the ISS has a number of features [nasa.gov] to keep temperatures regulated. Overall, space in LEO is cold (averaging 0 F). The problem is that it is far too hot on the sunny side (250 F) and far too cold on the shady side (-250 F). Therefore the ISS is extremely well insulated to maintain an even temperature across the entire inside. But this insulation leads to other problems -- heat builds up from all the equipment. Thus, the ISS has a giant radiator to dump excess heat into space.

    There are essentially two ways to feed astronauts in space: to send food with them, or have them grow their own. Both choices pose problems, and this article only looked at the first choice. I personally find the second choice, the growing of food in space, to be far more interesting.

    After all, even with months-long space station stays, today's space stations are the equivalent of summer camp compared to what future astronauts will go through. Even if warp drives prove possible -- an enormous if -- astronauts will have to spend years aboard spacecraft to even reach relatively nearby parts of interstellar space.

    That being the case, the growing of food in space becomes practically a necessity. As space voyages lengthen, it becomes laughably inefficient to produce on earth the tons of food neccessary for the trip , and blast it into space.

    Growing food in space poses all kinds of challenges that make today's pre-packaged problems look trivial. Right from the start, it appears that producing meat, milk, and eggs in space is going to be prohibitively inexpensive. So instead, NASA is funding investigations into growing plants hydroponically--probably extracting minerals from astronaut's crap and urine. Doing this gets around the problem of having to send tons of food into space.

    The challenges of having animal agriculture in space are so extreme that it appears that virtually all serious research on space-borne food production is confined to vegan foods. This is purely a practical thing -- it's not as though the scientists at NASA have developed a sudden interest in animal rights. In fact, current studies involving vegan food production in space involve using rats [heilpflanzen-welt.de] to assess nutritional adequacies of what's being grown.

    But vegans can take heart. Even if they don't bring down animal agriculture on earth by 2525, it's a fair bet that Major Tom, blasting towards the Dog Star, will be eating a vegan diet -- whether he likes it or not.

    The ISS is cooled down by emmitting infrared radiation through gigantic heat sinks that use two closed loops: one with water - to take the heat out of the stations interior and to the heat sinks and the oher with ammonia - to take the heat out of the water and into the heat sink tubing (ammonia freezes at a much lower temperature than water. Water would just become ice and would clog the tubes.) Now THIS is some heat sink that could solve heating problems of a huge super-computer.
    I wonder what did MIR use for cooling down? [russianspaceweb.com]

    I like this chronology [russianspaceweb.com] - a very exciting reading.

    I work for a local grocery chain in Houston and the store I worked at 2 months ago provides alot stuff to the ISS program. For instance, they order 110 lbs. of asparagus each time. What's interesting (but not suprising) is they called me to get the LOT number and other information pertaining to the origin of the asparagus. I had to direct them to our supplier but I thought it was cool in any case. Not to mention that I had a good sales ring that day...

    For example, there is no refrigerator or freezer aboard the Station, so food must remain good for long periods at room temperature.
    If the ISS doesn't have a refrigerator, then why does this picture [nasa.gov] have the following data plate in the upper right-hand corner:
    EX-3
    ONBOARD
    REFRIGERATOR

    Many male astronauts prefer to shave as little as possible, and all agree that it's one area in which their female colleagues have all the advantages.

    So women in space have hairy legs and hairy armpits? Cancel my ticket, I'll stay on Earth.
  • think about it eat all you want and still weigh next to nothing, literally. is space eating the next big diet?

    That explains this $136,216.20 proposal to NASA to study Development of Extended Shelf-Life for Tortillas for Long-Duration Space Missions" [uh.edu].

    They wanted to (or did?) use MRI scans of tortilla dough to determine whether there were any changes on a molecular level that could be linked to tortillas taking on a bitter taste after being on the shelf for extended periods of time.

    I wish I could get my own NMR spectrometer by saying that I want to study tortillas.

    Does anyone else find this to be hilarious?

    I mean, either suit up and stick anything in the shadow of the ISS and it'll be cold pretty darn quick, or mount a metal box flush with any exposed bulkhead directly connected to the skin of the ISS on the shadowed side - you'll have a bloody cold little cupboard in no time.

    I mean, it's not like it's rocket science. Well, wait...

    I recently attended a talk by a NASA education guy on the subject of living in space - on the shuttle and ISS. For the most part, it's really not that different from what you might expect; the main problem is not so much things intrinsic to zero gravity (though there's some of that with liquids, crumbs, etc.) but that NASA generally skimps on the sort of amenities you might think the astronauts could use. For example, there was no "table" on ISS, until the crew up there built one out of some surplus supplies. And, similarly, no refrigerator or freezer. Things will be quite different once the first space hotel [bigelowaerospace.com] goes up.
  • Who cares what they ate at ISS, I wanna know when they're going to have guests for Thanksgiving. =)
  • I doubt that they're eating anything specifically for Thanksgiving, seeing as none of them are from the US. (Michael Foale doesn't count, even if the UK does look more and more like the 51s state lately.)

  • For example, there is no refrigerator or freezer aboard the Station, so food must remain good for long periods at room temperature.

    ...or you could just put larger quantities in shielded canisters and leave them outside the station in the shade?

    I mean, if you're careful to make sure the container isn't air-tight, it would even be vacuum packed. How much better preservation do you need?

    Admittedly, the walk out to the fridge isn't one you'll make when you wake up at 3am wanting a snack...
