Scientists Harvest First Vegetables in Antarctic Greenhouse (apnews.com)
Scientists in Antarctica have harvested their first crop of vegetables grown without earth, daylight or pesticides as part of a project designed to help astronauts cultivate fresh food on other planets. From a report: Researchers at Germany's Neumayer Station III say they've picked 3.6 kilograms (8 pounds) of salad greens, 18 cucumbers and 70 radishes grown inside a high-tech greenhouse as temperatures outside dropped below -20 degrees Celsius (-4 Fahrenheit). The German Aerospace Center DLR, which coordinates the project, said Thursday that by May scientists hope to harvest 4-5 kilograms of fruit and vegetables a week.
Fucking penguins got in and destroyed all my beans....
I saw a documentary that showed an astronaut growing potatoes in his own crap. So it looks like it is has been done before. Why repeat it on earth all over again?
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
I would expect they would try to grow more calorie per kilogram vegetables then Salad Greens. Sure in industrialized areas, Salad Greens are nice for fillers, because we have no food shortages, so we like the crunch and the fact it will fill us up without extra caloric intake. But in Antarctica, I would put more effort into growing foods that will better sustain the people there, because getting food delivered is expensive and hazardous.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Since the linked-to AP article is mostly just a picture, with nothing on the tech., here you go:

Pretty cool, but maybe not space & cost effective on a spaceship.
Thank you comrade! Your secret mission to make Democrats look even dumber has been a huge success!
The term "pesticides" also includes herbicides and fungicides.
If your life depends on successfully growing a monoculture over several years in a sealed tin can, you might need to at least consider having some fungicides on hand. Not to mention, some mites are almost microscopic. Without any natural predators, one pair slipping through might also ruin your day.
Not only that, but hydroponically grown vegetables in Antartica have been grown for quite a while as well:

Come on Slashdot. I know this isn't a breaking news site but ....
Faster! Faster! Faster would be better!
Only -20C? They should try their experiment in Canada, where we have real winters, eh?

" by May scientists hope to harvest 4-5 kilograms of fruit and vegetables a week
Could you do that?"
Yes. I grew up on a small farm that produced several truckloads of vegetables every week. And yes, we started them under grow lights and greenhouses while there was snow on the ground. My father did this with only an 8th grade education.
Given enough space, heat, and lighting, 10 pounds of vegetables isn't very much. Looking at TFA, the scientist didn't look like he was working in a crammed environment, compared to any other greenhouse. Forgive me for being dismissive, but it's been done before.
"How much space do you need?"
Look at the picture in TFA. Take the amount of space in the photo, and divide that by the number of plants you see. If you do this carefully, you will notice that the room is quite spacious, compared to most greenhouses.
If TFA showed how the scientist created technology that can grow lots of vegetables in a tiny area, it might be impressive. But based on the article and photo provided, the scientist achieved about as much as a kid in a 4-H project.
It doesn't really matter, since space is infinite.

I think that what has happened here is that a fluff piece was written about a greenhouse that is performing actual science, but the science part was lost as it went over the head of the reporter.
It looks like they're testing various aeroponic setups, and might even be testing different strains of various plants.
Plus, while we know how to do it, they may be going for more exact numbers. How many days and hours? How much artificial light? What temperature? How much water? Etc...
The fact that it gives the scientists and workers down there fresh produce is a bonus.
