A hardy moss species survived 283 days on the outside of the ISS, enduring vacuum, radiation and extreme temperatures. More than 80% of its spores lived and germinated back on Earth. The findings reveal surprising resilience in early land plants and may support future Moon and Mars ecosystem designs.A hardy moss species survived 283 days on the outside of the ISS, enduring vacuum, radiation and extreme temperatures.
