Question: What sort of experiments take place in the lab and if so what experiments are they?

I grow microbes and then expose them to different kinds of harmful radiation that you also find in space ,like UV light or x-rays, to see if and how they survive. I’ve got the same experiments running on the outside of the ISS as we speak, so I’ll compare the two and see how microbes could survive on space 🙂
