Scientists put moss on the outside of the International Space Station for 9 months — then kept it growing back on Earth (www.livescience.com)

Moss spores have survived a prolonged trip to space, scientists reveal. The spores spent nine months on the outside of the International Space Station (ISS) before returning to our planet, and over 80% of the spores were still able to reproduce when they arrived back on Earth.

The discovery improves our understanding of how plant species survive in extreme conditions, the researchers wrote in their findings, published Thursday (Nov. 20) in the journal iScience.

“Staged” water/fuel tanks (a thinly shielded outside + “storm cellar” for bad bursts) seem to be the most viable form of shielding, but there are a few proposals like external algae farms.
