Asteroid eating fungi
Set them free to devour the organic chemistry on asteroids so they create the soil they created on Earth. Then plant food on them so we can eat on the way to the stars. I saw this idea on a Scott Manley YouTube video and was intrigued.







Stranger than fiction, from the NASA website… “The myco-architecture project out of NASA’s Ames Research Center in California’s Silicon Valley is prototyping technologies that could “grow” habitats on the Moon, Mars and beyond out of life – specifically, fungi and the unseen underground threads that make up the main part of the fungus, known as mycelia.”
Too late if you want to keep the solar system clean of these little killers, they decide which plants they allow to exist on earth, and therefore we are only here but for the grace of fungi.
It’s everywhere. only tardigrades will survive in space now, the die is cast.
This is likely the video the op is referring to https://youtu.be/ma_175NNfZs
NIAC funded this research already. Who knows what will come of it but there are plenty of planets out there that could do with a bit of a garden if you ask me.
