NASA's ISS Has Become a Mini-Garden for Moss Spores
In a breakthrough that could have significant implications for future space exploration, researchers have successfully grown moss spores on the outside of the International Space Station (ISS) and back on Earth. The finding comes after nine months in space, where the delicate spores had to survive extreme conditions such as UV radiation, vacuum, deep-freezing temperatures, and high levels of radiation.
The experiment, led by Dr. Tomomichi Fujita from Hokkaido University in Japan, exposed different types of moss structures to a simulated space environment on Earth before sending them to the ISS onboard the Cygnus NG-17 spacecraft. The most resilient spores were those encased in a structure called a sporangium and had an incredible ability to withstand harsh conditions, even exceeding 100,000 joules per square meter of UV radiation.
After being exposed to these extreme conditions for nine months, the researchers found that nearly all of the moss samples showed high rates of germination upon their return to Earth. This is remarkable considering some of the samples had been fully exposed to space radiation and still managed to sprout at a rate of 86%. However, it's worth noting that the chlorophyll in the space-exposed samples did show signs of degradation.
The implications of this study are significant for future long-term missions on other planets. Dr. Fujita believes that mosses could one day help turn barren dust and rocks into fertile soil through oxygen generation, humidity control, or even soil formation. While the study focused on survival under space exposure, further research is needed to determine if these resilient spores can also grow and thrive in extraterrestrial environments with different gravity levels, atmospheric compositions, and radiation levels.
While some experts welcome this discovery, others note that it's just one part of a larger puzzle when it comes to establishing sustainable ecosystems beyond Earth. Dr. Agata Zupanska from the Seti Institute says that while spore resilience is important, it represents only an initial step towards more complex goals such as actively growing plants in extraterrestrial environments.
Ultimately, this study highlights the incredible adaptability of certain plant species and opens up new avenues for research into sustainable life-support systems in space.

! Nine months is just too long, what if I want a quick green fix? Can we get some simpler experiments going here? Like, can they just try growing a basic radish or something in space?
. Come on guys, be real about it, we're not talking about planting a whole forest in space here.
. Can we just focus on getting the ISS working properly first?
But seriously, it's kinda mind-blowing that these spores can withstand all that radiation and still manage to grow. I mean, we're talking 100,000 joules of UV radiation - that's like, a lot! 
And the fact that some of them are already showing signs of degradation when they get back to Earth is actually kinda fascinating too... it's like they're trying to tell us something about what's gonna happen in space. 
. I mean, who needs actual greenery when you've got some tiny little spores that can withstand all that radiation? It's just a drop in the bucket for establishing sustainable ecosystems beyond Earth... good luck with that 
. It's just some scientists trying to save face after all these years of failed space missions 
.
But for real though, this study has huge implications for future space missions. Imagine having plants grow in space, making it possible to turn barren rocks into fertile soil... it's like something straight out of Star Trek! 
But seriously, this is actually kinda cool! I've been following this experiment and it's crazy to think that these tiny little spores were able to survive all those harsh conditions in space. Like, who knew they could handle 100k joules of UV radiation?
