Scientists Find Desert Moss ‘That Can Survive On Mars’ (theguardian.com)
Posted by BeauHD from the promising-plants dept.
Scientists in China have found a species of moss that is able to withstand Mars-like conditions. The species is called Syntrichia caninervis and it’s found in regions including Antarctica and the Mojave desert. The Guardian reports: “The unique insights obtained in our study lay the foundation for outer space colonization using naturally selected plants adapted to extreme stress conditions,” the team write. […] Writing in the journal The Innovation, researchers in China describe how the desert moss not only survived but rapidly recovered from almost complete dehydration. It was also able to regenerate under normal growth conditions after spending up to five years at -80C and up to 30 days at -196C, and after exposure to gamma rays, with doses of around 500Gy even promoting new growth.
The team then created a set-up that had similar pressures, temperatures, gases and UV radiation to Mars. It found the moss survived in this Mars-like environment, and was able to regenerate under normal growth conditions, even after seven days of exposure. The team also noted plants that were dried before such exposure faired better. “Looking to the future, we expect that this promising moss could be brought to Mars or the moon to further test the possibility of plant colonization and growth in outer space,” the researchers write.
