Growing Vegetables In Space, NASA Astronauts Tweet Their Lunch

An anonymous reader writes: Astronauts on the International Space Station got their first taste of space-grown lettuce today. It took the astronauts about an hour to harvest and prepare the lettuce both plain and with oil and vinegar. The Times reports: "The vegetable experiment had been a long-awaited harvest for the astronauts, who say that the ability to grow and sustain crops in space may someday aid travelers on long space trips. Cultivating crops is seen as a critical step in the path to traveling to Mars, for instance. Before the harvest, the astronauts did what any sensible Earthling with a Wi-Fi connection would do: They celebrated lunch in an exclusive locale by tweeting a picture of the goods."

Lettuce should not be pink

[sims 2]

I hate to tell you this but the lettuce has gone bad.
Lettuce is not naturally pink.

It must have something to do with that space radiation I keep hearing about

You're right. Real space food is B-L-U-E.

Re:Lettuce should not be pink

[theIsovist]

I imagine you're joking, but for those who don't know - the lettuce in the picture is a shade of pink due to specific wavelengths of lighting that provides the plants with the ideal amount of "solar" energy, while avoiding providing any stressful wavelengths that require the plant to shed heat. In actuality, the plants often look almost black under that light, because they absorb most of it. Under regular sunlight, plants look green because that wavelength is reflected back, unused.

It may look unnatural, but it's surprisingly efficient.

Lettuce has almost no nutritional value. They should be experimenting with beans or root crops like carrots.

We have already established the nutritional value of lettuce on Earth. This experiment is to grow it, plus a variety of other dietary favorites, in space.

Spirulina [wikipedia.org] seems like an obvious choice. It could be grown in tubes external to the station. It would have a side benefit of filtering water, removing waste and providing a supply of oxygen.

Although beans might get an astronaut to move faster in zero gravity from the expanding gas, the smell left behind in the cabin will probably get them cast out of an air lock without a space suit.

Beans in an enclosed air system? You monster!

Re:

[sims 2]

Yep.
I have seen some of the led grow light setups for sale online i assume that's what they are using.

However I would have preferred to see a picture of the lettuce under a more natural light as under that pink light it looks a blackish pink as well as being hard to see.

It looks like one of those black snake fireworks if they were pink.

How can we raise space cattle without space alfalfa? One step at a time, meat lovers. One step at a time.

Must do what The People want

[Impy the Impiuos Imp]

"We grew all the cool stuff of farmers -- I ate lettuce, and kale, and wheat grass, pressed with a $8,000,000 space crusher crank, and asparagus, which we placed into bulbs of water and then drank the water."

Negative calories

[XxtraLarGe]

It took the astronauts about an hour to harvest and prepare the lettuce both plain and with oil and vinegar.

Sounds like they burned off more calories than they gained in this exercise.

Day of the Triffids

[khr]

I guess I should check the TV listings to see if any channel is showing "The Day of the Triffids."

Re:

It's on youtube. /watched it a few weeks ago. I don't know why

We need a bigger station

Re:

No, we just need a greenhouse module for the ISS that will use natural light to grow vegetables. Then they might want to edge into the protein realm. Though it will be a long time before we will be able to have cows in space (cue the trolls!) the vegetable module could raise these:

I have tried them, and they are remarkably good.

Re:

[stackOVFL]

Cricket bars eh? hmm I think I'll stick with my forest sized domes on a make believe space ship. They have to drop the sound track though. That just drove me nuts after awhile.

Re:

[grahamsz]

I thought they were kinda weird and disappointing. The combo of chocolate and flour just didn't seem like the right texture.

No real issue with insect protein, but i'm not rushing back to the store to get more cricket bars.

But what about Pigs [youtube.com]?

(It just occurred to me that Disney owns both of these now...)

Spherical cows should be OK, they live in a vacuum.

Re:

Raising cows is not really the optimal way of synthesizing proteins in a constrained environment.

Consuming GMOs (gravitationally modified organisms) has been shown to cause Autism in space monkeys.

Make sure to pack energizers

[dfn5]

OK, we've fixed the airlock. Do you need more planters, more nutrients? Whatever you need, you've got it.
We need new seed.

Veggies in space

[PopeRatzo]

You can't beet fresh veggies grown in space. It'll lettuce have a more varied diet on long space flights.

Rocket?

[roesti]

Did they grow rocket? (groan)

Vegetables grown in space for years

[NewsWatcher]

The article seems to imply that these are the first ever vegetables grown in space by astronauts, but this isn't true.

According to NASA's website about the International Space Station [nasa.gov] "Since 2002, the Lada greenhouse has been used to perform almost continuous plant growth experiments on the station. Fifteen modules containing root media, or root modules, have been launched to the station and 20 separate plant growth experiments have been performed. "
