My space potato spreading its roots in microgravity

  1. In my off-duty time on Expedition 72 to the ISS, I grew potatoes in an amateur microgravity experiment. As noted in “The Martian” they are excellent nutrition sources and will likely be useful in future deep space horticulture. Absent gravity, the roots (fuzzy tendrils near opening) would grow haphazardly to find soil or water, and were bagged for containment, the closest thing we had for pots. Maybe one day potatoes will grow on Mars! Until then, we learn what we can in Earth orbit.

    Well that’s just rad… grow some leeks too and you’ve got the makings for a tasty space soup

  3. I wonder how complex life will get when adapting to off world conditions. If it can actually react “ecosystem” situations or if it will have to be small islands of life.

  4. Astronauts posting on Reddit? So here for this!

    Keep doing what you’re doing, this is awesome!

  5. Thank you for sharing all of those photos from ISS, always a pleasure to see those on Reddit!

    Did you use your own poop? Because, apparently that’s a part of growing space potatoes. Saw it in a documentary about the time Matt Damon was an astronaut for NASA. 

  7. I saw a picture of the space station getting a delivery of fruits and vegetables and they looked very happy. I wondered, is there not extensive research going into horticulture on the ISS, especially for deep space missions into the future? Growing potatoes is one thing, but what about tomatoes, berries, kale, spinach, lettuce, etc? What about a rotating chamber to simulate gravity?

  8. imagine potato becoming the dominant interstellar species because we introduced it to other planets. Mankind perishes, potato evolves.

  9. Hey, the roots are all over the place obviously due to no gravity. However, im curious how fast they would have to spin in order to correct their growth. Roots sense gravity by sedimentation with amyloplasts in their caps.

    Thanks for sharing!

    I love the science you guys do testing the future of agriculture and food in space! I’m a chef down here, and seeing you guys work on things that I can understand the context of (slightly) is thrilling and makes me think of what we may be able to do together in a few generations.

    Did you happen to be part of the miso fermentation experiment a little while back on the ISS? I thought the increased pace could have been to a number of uncontrolled factors, but the possible explanations that were more radiation and exposure based were fun to think about!

    Little guy is all “where’s the dirt? Which way is down? It isnt supposed to be this hard, man.”

  12. Thank you for sharing! I have been dying for an update. It looks like it is making good progress.

  13. Is there another phase for the experiment where they are grown in a centrifuge?

    Usually in scifi, the centrifugal habitats need to be very large for humans, but for a potato farm; how small could it be?

    Go go Space Potato! 🚀🥔

    Thank you for sharing this charming part of space science with us!

    So fucking interesting.

    What happens with a potato that you take outside? Humans would boil and expand without spacesuit, right? Could you take it out or throw it into the void?

    Please don’t tell me you guys are doomscrolling on the ISS! 🤣

    It looks… Confused.

    Also, I think that’s the first time a human has constructed that sentence.

    Fly safe!

  17. That’s the first time I’ve ever seen a potato form air roots. 😄 Thanks for sharing!
