There may be ancient bacteria under the surface of Mars

According to a study published in the journal Astrobiologya studyunder the surface of Marsmay harbor ancient bacteria. Mars is dry and cold, with an average temperature of minus 63 degrees Celsius in the mid-latitudes. In an even harsher environment, Mars is also constantly bombarded by intense galactic cosmic radiation and solar protons. To explore whether life could survive these conditions, the researchers first determined the ionizing radiation survival limit for microbial life. They then exposed six species of terrestrial bacteria and fungi to the simulated surface of Mars and shocked them with gamma rays or protons to simulate radiation in space. Ultimately, the researchers determined that some terrestrial microbes have the potential to survive on Mars on geological timescales of hundreds of millions of years.ResearchersFind, a powerful microbe, Deinococcus radiodurans (also known as “Conan bacteria”), especially adapted to survive the harsh conditions of Mars. Buried just 10 centimeters below the surface of Mars increases the lifespan of the Conan bacterium to 1.5 million years, research has shown. If buried 10 meters underground, the bacteria can survive for up to 280 million years.
