Space Garden
Have they done any growing of vegetables yet in space? Is it possible?
Do the plants know which way is up? Do they use human waste for fertilizer? Do they need plant lights? I have not seen any recent reports on this. -- The tobacco companies added ingrediants to make it more addicting to increase consumption. The food companies would never do that, right? Right? Right? |

A quick google search turns up a number of results:

I have not seen any recent reports on this. It's technically possible. The hurdle you run into right up front is that fairly trivially you can, using technology known since the 1950s, get all the supplies you need into about a kilo a day per person. Now, you have to work out if you can fit your garden into a smaller mass than this, it's not a easy task. |

I've heard the roots grow up toward the light sometimes, but the plants seem to do fine. Do they use human waste for fertilizer? Not yet, not that I know of. Do they need plant lights? Yes, AFAIK. I have not seen any recent reports on this. There's a website with quite a few articles about plant growth in space, called www.google.com Some examples: *http://liftoff.msfc.nasa.gov/Shuttle...ime/pao23.html *http://www1.dupont.com/NASApp/dupont...06_10_03a.html *http://www.nasa.gov/lb/missions/shuttle/pesto.html Key words used: 1) vegetable experiment shuttle 2) wheat experiment shuttle Mike Miller, Materials Engineer |

And get rid of waste water, perhaps use some local materials (Moon/Mars). Regards Carsten Nielsen Denmark |

What's life like living on a kilo a day? Baby food out of a tube? Baby food and/or tube food is almost all water, the last thing you want for efficient packaging. You'd eat freeze-dried or dehydrated food -- quite like what you'd eat on a backpacking trip, perhaps packaged a bit differently -- rehydrated with recycled water. Uninspired, but reasonably varied and pleasant, menus. Occasionally, as a break from routine, a bit of frozen whole food or a vegetable or two grown on board. (It *is* worth growing a few plants, partly as a diversion and partly to add some variety, although they wouldn't be a major component of the diet.) Yes, recycled water. Nobody, but nobody, gets by on a kilogram a day without water recycling. You need more than that just in drinking water, and when you figure in showering, dishwashing, and laundry, you've got to recycle almost all of it. You can recover enough *potable* water for drinking and food preparation from air dehumidification, using water vapor from washing as well as from people. You need enough non-potable water -- sterile and safe but perhaps not looking pure or tasting good -- to require recycling all three kinds of wash water, and recovering most of the water from urine. You can accept some small water losses, because human metabolism converts food to CO2 and water, so any system which isn't doing food recycling shows a water excess. So you don't need to recover water from solid wastes, and you don't need full recovery from urine. -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |
