Report Space-grown lettuce is as safe and nutritious as Earth lettuce, new research shows

In August 2015, Japanese astronaut Kimiya Yui trimmed a few leaves of red romaine lettuce and passed them to NASA astronauts Scott Kelly and Kjell Lindgren. Each drizzled a few drops of dressing onto the precious produce, then popped it directly into their mouths.

“That’s awesome, tastes good,” Lindgren said.

The International Space Station (ISS) harvest was too scant for a proper space salad, especially since half the crop was sent back to Earth for scientific analysis, but the munchies marked a milestone in human spaceflight. It was the first time an orbiting crop was grown with NASA hardware and then eaten. (Though scientists suspect astronauts might have stolen a few bites from a previous sample.)

We now know that space lettuce doesn’t just taste good. It’s also safe to eat and as nutritious as lettuce grown back on Earth, according to a new study published in the journal Frontiers in Plant Science.

From 2014 to 2016, astronauts grew “Outredgeous” red romaine lettuce inside the ISS Vegetable Production System chambers, or Veggie. Meanwhile, scientists at NASA’s Kennedy Space Center ran a control experiment that tried to precisely replicate Veggie’s conditions by beaming temperature, humidity, and carbon dioxide measurements back to Earth.

When NASA researchers tested both versions of the lettuce, they found the space-grown variety was strikingly similar to the ground-grown controls. Each had equivalent levels of nutrients and antioxidants. Cutting-edge DNA analysis even showed that the space lettuce also developed the same diverse microbial communities as its terrestrial counterpart. Researchers say that caught them by surprise. They’d expected the ISS’ unique environment to allow unique microbial communities to thrive there. And neither crops showed signs of potentially problematic bacteria like E. coli.

But researchers say they still have a long way to go before astronauts can help themselves to a cosmic salad bar. This lettuce was a kind of gateway plant. It’s easier and faster to grow than most fruiting crops, yet it thrives in similar conditions. Now scientists need to figure out how to nurture slower-growing plants.

    My boyfriend is super into Bethesda modding so I'm probably going to join him in that for a bit, then move on to making mobile/browser games.
  • C Cherry.Grove:
    I mostly just want to look at my old projects because I know I posted uploads on here somewhere.
  • C Cherry.Grove:
    My one game was basically Among Us but you sabotaged an entire medieval city simulated drastically inefficiently with dynamic NPCs :S
  • C Cherry.Grove:
    of course I never finished it x D
  • jonas jonas:
    xD
  • jonas jonas:
    I think you can still run the original game, just there's a chance your map won't work with the newer patches
  • jonas jonas:
    what development framework have you been looking at for mobile development?
  • jonas jonas:
    I'm currently creating (as a hobby) a space invaders like game for mobile using Xamarin, after starting a few larger projects that I also may not have finished :rolleyes::p
  • The Helper The Helper:
    Awesome! you should look at the Atari VCS platform it does not have a huge user base but the one it has is super active at around 11k and they have no games in there store
  • The Helper The Helper:
    basically it is linux
  • The Helper The Helper:
    OMG it is BanLord as Blackveiled on the forum
  • The Helper The Helper:
    what is up buddy
  • jonas jonas:
    thanks for the tip, that sounds cool. Never heard about the VCS before but seems like it should be a good match
  • tom_mai78101 tom_mai78101:
    The winter vacation left a toll on me. I missed staying up late and sleeping in late.
  • C Cherry.Grove:
    i haven't looked into it yet
  • C Cherry.Grove:
    If I could use something Python compatible it would save me some learning
  • C Cherry.Grove:
    But Unity might be easiest
  • C Cherry.Grove:
    looking at old posts here makes me happy. Makes me be all like "wow I was pretty smart in 2009"
  • C Cherry.Grove:
    mostly failing at life through adulthood really demotivated me for a while
  • C Cherry.Grove:
    ....what I don't get is why the fuck they would force us to permanently convert to a version of the game everyone fucking hated : \
  • C Cherry.Grove:
    Raid Shadow Legends texture pack smh
  • jonas jonas:
    Most people fail at life throughout their adulthood. Sometimes we get to learn from it. Usually it just feels like crap.
