HOW NASA GROWS PLANTS IN SPACE

[@termi_sh]

it's criminal how underrated your content is

[@lewismassie]

I've actually wondered about this kinda stuff for a while, awesome to finally see the real detail on ISS experiments

[@d33w]

You're a space farmer, how freaking cool is that?

[@TZeroSystems]

It Aint much, but its honest work

[@eddiesland93]

So awesome its amazing

[@YF-23]

I really, really enjoyed watching this video, you do a very good job at explaining stuff like this. You should consider making more of these kinds of videos, I would definitely watch them! Good job!

[@TZeroSystems]

Noted!

[@felixwebb1466]

This video is really interesting

[@stevato0449]

I really liked this video! You're carrying out a really important job and its really cool to see a very up close example of what an ISS experiment looks like

[@justepourlacheruncom8393]

Has a former plant biology student who worked in growth room and green house I'm very impressed. I particularly like the concept of "science block" for rationalizing the experimentation in term of time and space with standardized material. Even with arabidopsis creating adapted growth and experimentation material is an important part of the job. Which means every laboratory has his little trick and accumulated experience for running things. And it's hard to replicate this because skills are not something you could learn with research paper. Often people internship and PHD are kind of "jack of all trade" making everything which mean it's hard to delegate or replicate there work. It's interesting to see how tailoring science plateforme to be spatialized and run by astronaut could help repeatability on earth.

[@TZeroSystems]

yeah and even with that on occasion it just doesn't play ball. It took like 4 runs to get the soil change that was made to have a common control.

[@justepourlacheruncom8393]

@@TZeroSystems That’s why hydroponic is so popular among scientists. It’s way much simpler to control the composition of nutrient solution you create yourself with easy to source supplier, know chemistry, and quick analysis. When everything is mineral, everything is (quite cheaply) measurable. Out of curiosity, do you know where I can find information about these sciences block ?

[@caelananimation]

Amazing video. I can’t wait to see you do a full video on your Dream Chaser job too

[@TZeroSystems]

Eventually, I hope I get to. Its a lot harder with private companies and production floor is really controlled. Maybe closer to flight

[@esar0566]

Great job. Very interesting video.

[@joehunter9928]

Great job this was so cool to see

[@logovobotanika]

Очень здорово, что наука остаётся открытой несмотря ни на что. продолжайте ваше благородное дело!

[@mojonojo]

This is so cool! I'd definitely love to see more stuff like this.

[@TZeroSystems]

Awesome, thank you!

[@oneswtl8y]

Hi! PH04 science team lead here! Great video! I don't believe that I've met you b4? Looking forward to possibly meeting you during the upcoming PH07 experiment

[@TZeroSystems]

Woo! I haven't been involved as much but if you have met Fulps on our team ask him to text Rob to come down stairs! It's likely I'm there!

[@Ilovethebush]

this design requires spherical construction like a tiny planetarium and glass blown features or mould cast steel, possibly magnetic to allow a light to move over the plants from a 'created east point' to a 'created west point' changing the angle daily to mimic seasonal changes found in the natural earth environment.

[@ianinpitani5016]

Hi, I have a question, how does the irrigation work? Is water delivered straight to the substrate inside the science carrier? Thank you

[@emptyfueltank]

I wonder what kind of plant could grow with the sunlight you get outside of our atmosphere. Maybe a rotating hydroponic farm room that always faces the sun could work too

[@julianholstein3840]

Amazing video! So do you figure things out on a 3rd unit and then carry it out simultaneously on earth and station or is there an delay between the control and the actual experiment?

[@TZeroSystems]

So kind of. We had an issue with the in space one and we trouble shot it on the ground to figure out a fix and then used that plan and fix to send components to do the repair on orbit.

[@dylanfrost2743]

Hey Rob, this video is great! Thanks for sharing this. What a cool opportunity for a side project. Do the control experiments run at the same time as the experiments on station? Or do you perform the control first? Does all of the "practice" on the ground lead to station unit downtime?

[@HiltTilt]

I'd be really curious to know how plant pest react to being in space, like Spidermites and Fungus Gnats. Would they even be able to survive?

[@edwardchege2623]

How does Negative geotropism work here?

[@TZeroSystems]

Basically don't see it. Even during Ukrainian invasion cosmonauts were collaborating with US astronauts on US soil

[@Simon-gr8jh]

Lets say that we had the opportunity to create a sort of "artificial" gravity on the iss, would you say that growing in microgravity is such a big complication that investing in artificial gravity would be worth considering? Or is it really not that big of a problem to grow food in microgravity? I would really appreciaty your opinion on this since I am considering working on this topic in university.

[@rubenwardy]

this was really interesting, thanks

[@TZeroSystems]

My pleasure!

I want to see what a space pumpkin looks like

Cube pumpkin time

See the Ghost 👻 & digital pepper 🫑🌶️ are on the way!
