PremierLeague-News.Com - Breaking Sport Transfer News ! Some tiny microscopic organisms, such as black mould fungus, may be able to survive on the surface of Mars, at least temporarily, a new study suggests.Researchers exposed samples of bacteria and fungi to Mars-like landing conditions for five hours by launching them 24 miles up into the Earth’s stratosphere, which closely represents the conditions on the Red Planet.“We used a scientific balloon to fly our experimental equipment up to Earth’s stratosphere. Some microbes, in particular spores from the black mould fungus, were able to survive the trip, even when exposed to very high UV radiation,” said Marta Filipa Cortesão, from the German Aerospace Centre in Cologne.The i newsletter latest news and analysisEmail address is invalidThank you for subscribing!Sorry, there was a problem with your subscription.The findings suggest that some kinds of microbes could potentially upset the Martian eco-system if inadvertently introduced to the planet by a space craft.When searching for extra-terrestrial life, we need to be sure that anything we discover has not just travelled with us from Earth, the researchers said.

. They could help us produce food and material supplies independently from Earth, which will be crucial when far away from home,” said Katharina Siems, also of the Aerospace Centre.The study also involved researchers from NASA and is published in the journal Frontiers in Microbiology.“We launched the microbes into the stratosphere inside the MARSBOx (Microbes in Atmosphere for Radiation, Survival and Biological Outcomes experiment) payload, which was kept at Martian pressure and filled with artificial Martian atmosphere throughout the mission,” said Dr Cortesão. “The box carried two sample layers, with the bottom layer shielded from radiation. This allowed us to separate the effects of radiation from the other tested conditions: desiccation, atmosphere, and temperature fluctuation during the flight. The top layer samples were exposed to more than a thousand times more UV radiation than levels that can cause sunburn on our skin.”
