> Thanks, I was really only looking for a picture of the space lettuce This is Veggie, the apparatus on the ISS used to make the lettuce for the studies seen in the article: https://www.youtube.com/watch?v=y9aR2-7sOjg https://www.youtube.com/watch?v=y9aR2-7sOjg I'm deeply fascinated with the food supply/chain in longterm Space Travel and colonization. Lettuce is low hanging fruit, I hope that we see a vast amount of innovation in this space that allows for greater (ideally autonomous) modular growing spaces. This is a critical component to having a permanent settlement on Mars, having to rely on re-supply missions from Earth (Starship will drop the cost significantly) is untenable when you start scaling the population beyond an outpost.

  >>"I'm deeply fascinated with the food supply/chain in longterm Space Travel and colonization" You could be interested in these guys[1]. They are collaborating with ESA in that subject. The Youtube interview[2] is really interesting.

    Pretty cool, the developments of getting edible protein from atmospheric elements sounds really rad, especially if they're targeting using renewables. Personally, I think for terrestrial use it will have limited applications as Ag can deliver plant proteins with great efficiency, animal less so, but if given a choice over a soylent-green type slury or an egg piece or grilled chicken I think I'd opt for the egg/chicken every time. My diet is already optimized at a 7:1 plant to animal protein ratio, I don't think I can go any higher on the plant side without compromising my strength training as I need lots of HDL fat to recover. However, I wonder how this tech would work on the way to Mars and once there since there aren't any external sources to derive them from? Martian atmosphere is ~3% N, as opposed to ~78% on Earth. I understand they want to create a closed-loop system with re-utilization, but I wonder if they will need to develop some sort of tech to efficiently extract the N from urea when re-processing the water and then use it that way. That';s my best guess, because its about ~6 months to Mars and there is no way a payload with Humans, equipment, supplies, water can sustain them for that long. Either way, I bookmarked there site and will periodically check it out, thanks!
