Chinese Scientists Discover Moss That Can Survive on Mars

Chinese scientists have discovered a type of moss that can survive and even grow in conditions similar to those on Mars, including extreme cold and radiation. This moss, known as Syntrichia caninervis, is not edible but could be very important for long-term space missions. It can convert carbon dioxide and water into oxygen and carbohydrates, which are essential for human survival.

The moss, which is found in harsh environments like Antarctica and the Mojave Desert, was tested in a lab where scientists recreated the tough conditions of Mars. The moss survived five years at temperatures as low as minus 80 degrees Celsius and was able to regenerate after almost completely drying out. It also showed strong resistance to radiation, even growing under small doses of gamma rays. The researchers published their findings in The Innovation journal, stating that this study could help in future space colonization efforts.

Growing plants from Earth on Mars could make the planet more livable. Stuart McDaniel, a moss expert from the University of Florida, explained that plants are crucial for long-term space missions because they turn carbon dioxide and water into oxygen and food. Although this particular moss cannot be eaten, it could still provide other important benefits in space.

However, there are still many questions that need answers. McDaniel pointed out that while these experiments are a good start, they do not prove that the moss could produce enough oxygen or reproduce effectively on Mars. Despite these challenges, the Chinese researchers are hopeful about the future possibilities of using this moss in space missions.
