On my search for space news for my non-fiction piece this week, I could not pass up the opportunity to learn more about this.
The technique involves a GMO E. coli strain. And the process seems quite simple really. The poop is left for several days to increase its Volatile Fatty Acids. Then those VFAs are extracted via centrifuge and filtration. The extracted VFAs are left to ferment in special tanks, where they get all cozy with the fancy E. coli bugs. Then using a fucking 3D printer (!) the astronauts can print whatever they want!
The process will be tested in a low-grav aircraft this July.
This world is so amazing and exciting. I love being alive in this little slice of our existence. In a world where nanobots and vaccines and 3D printers and AI are more than just Sci-Fi.
Good luck and Godspeed, poop warriors!
I wonder if they are using their own poop to do the tests or if they are taking poop donations…
