Moss spores survived in space for 9 months

Moss spores spent nine months exposed to the harsh conditions outside the International Space Station, enduring vacuum, radiation, and extreme temperatures that would kill most life forms. When researchers brought the spores back to Earth, an impressive 86 percent successfully germinated and began growing normally. This remarkable survival adds moss to a select group of organisms that can withstand extended space exposure, potentially opening doors for future plant cultivation on Mars or the moon to support astronaut missions.
