Desert moss found with potential to thrive on Mars

Scientists have identified a species of desert moss called 'Syntrichia caninervis' that could be a game-changer for future space exploration and colonisation efforts.

This resilient moss has demonstrated an exceptional ability to survive in conditions comparable to those found on Mars, raising hopes for its potential use in establishing sustainable habitats beyond Earth.

The moss is renowned for its tolerance to drought conditions, but recent studies have revealed its remarkable capacity to withstand temperatures as low as −196°C, high levels of gamma radiation, and simulated Martian environments. Interestingly, prior dehydration appears to enhance the moss'ability to cope with these extreme stressors.

Researchers asserted that 'S. caninervis'surpasses even highly stress-tolerant microorganisms and tardigrades in its environmental resilience.

"Our study shows that the environmental resilience of *S. caninervis* is superior to that of some of highly stress-tolerant microorganisms and tardigrades," they added.

They believe this moss is a promising candidate for pioneering plant colonisation beyond Earth, potentially paving the way for sustainable human habitats in extraterrestrial environments.

Unlike previous studies that focused on microorganisms, algae, lichens and plant spores, this research uniquely examined the resilience of whole plants to extreme conditions akin to those on Mars.

S. caninervis haswidespread global distribution

'S. caninervis' is a globally distributed moss species that thrive in severe desert environments like Tibet, Antarctica and circumpolar regions, forming part of the resilient biological soil crust.

The researchers conducted rigorous tests in controlled laboratory settings to assess the moss'tolerance to extreme cold, gamma radiation and simulated Martian conditions.

The results were astounding, with the moss demonstrating a remarkable ability to regenerate after being subjected to these harsh environments.
