The Chernobyl exclusion zone may be off-limits to humans, but ever since the Unit Four reactor at the Chernobyl Nuclear Power Plant exploded nearly 40 years ago, other forms of life have not only moved in but survived, adapted, and appeared to thrive.

    This appears to be supported by the findings of a 2022 paper, in which scientists describe the results of taking C. sphaerospermum into space and strapping it to the exterior of the ISS, exposing it to the full brunt of cosmic radiation.

    There, sensors placed beneath the petri dish showed that a smaller amount of radiation penetrated through the fungi than through an agar-only control.

    The aim of that paper was not to demonstrate or investigate radiosynthesis, but to explore the fungus’s potential as a radiation shield for space missions, which is a cool idea. But, as of that paper, we still don’t know what the fungus is actually doing.

    That’s where it seems really cool to me. If we have nuclear spacecraft or even just passive cosmic radiation exposure, what’s otherwise a waste/threat could become a factory. Reinforcing the hull with a regenerative radiation shield, genetically engineering it like E. coli to biosynthesise needed compounds, mass producing it as food for something we can eat- it’d be so useful to have something like that in space where you’re surrounded by energy you can’t use.

      into space and strapping it to the exterior of the ISS, exposing it to the full brunt of cosmic radiation.

      The USS isn’t that far out in space; it’s in LEO, well within the Earth’s magnetic field, and therefore protected from most cosmic radiation. But not all.

      That doesn’t make the experiment invalid, just the phrasing inaccurate.
