Researchers found that the moss could recover its photosynthetic and physiological functions almost immediately after rehydration, even after losing over 98% of its cellular water content. Additionally, the moss can endure ultra-low temperatures, regenerating after five years in a freezer at minus 80 degrees Celsius or a month in liquid nitrogen. Syntrichia Caninervis is found in various extreme environments, including Xinjiang, Tibet, a desert in California, the Middle East, and polar regions. This discovery comes as both China and the United States accelerate their space exploration efforts, with upcoming missions aimed at studying Mars and other celestial bodies. China’s space missions include the near-Earth asteroid probe Tianwen-2 next year and Tianwen-3 around 2030 to bring back samples from Mars. Meanwhile, NASA has devised a 20-year plan for Mars exploration to determine if the planet is habitable for humans.
Discussion Questions:
- Have you ever encountered a plant or organism that surprised you with its ability to survive extreme conditions? If so, what was it? If not, what conditions do you think such organisms would need to survive?
- Have you ever read or heard about research similar to the study on Syntrichia Caninervis? If so, what did you learn? If not, what would you expect scientists to discover about plants in extreme environments like Mars?
- Do you agree that the discovery of Syntrichia Caninervis could be a significant step towards making Mars habitable for humans?
- Considering the extreme conditions on Mars, what other qualities would plants or organisms need to have in order to successfully contribute to sustainable ecosystems?
- What aspects of Mars do you think are most important for scientists to understand before humans can safely live there?
