Life from Earth could temporarily survive on Mars

Some microbes on Earth could temporarily survive on the surface of Mars, finds a new study by NASA and German Aerospace Center scientists. The researchers tested the endurance of microorganisms to Martian conditions by launching them into the Earth's stratosphere, as it closely represents key conditions on the Red Planet. Published in Frontiers in Microbiology, this work paves the way for understanding not only the threat of microbes to space missions, but also the opportunities for resource independence from Earth.
