Mosses are already known for coping with harsh radiation, dehydration, and long freezes. Now scientists have pushed them even further by exposing their spore capsules to open space for nine months, and most of them survived. The team worked with spreading earthmoss (Physcomitrium patens), a small moss species used widely as a plant model by researchers. Its spore-containing capsules were mounted on the outside of the International Space Station (ISS), where they experienced direct solar radiatio...
