Moss survived 9 months in space, could still reproduce after return to Earth

A new study from Hokkaido University found that moss spores survived nine months in outer space on the exterior of the International Space Station.

Despite harsh exposure to radiation, vacuum, extreme temperatures, and UV light, more than 80% of the spores remained viable, though their chlorophyll degraded.

Different moss species showed unique stress-resistance traits, including protection against UV radiation and intense heat.

After returning to Earth, the spores were still able to germinate normally, demonstrating remarkable resilience, CBS News has reported.

Researchers say the results highlight the potential of terrestrial plants to survive extreme environments and could inform future efforts to support human habitats on the Moon or Mars.
