As such, scientists are researching the potential for life beneath the planet’s surface by studying its chunks of rock.
They found that one million microbes can live in just one kilogram of rock, conditions similar to samples on Earth.
Earth’s surface on Mars is likely to be quite difficult to inhabit given its already ravaged conditions by dust storms, solar wind and cosmic rays.
According to the study’s lead researcher and National Aeronautics and Space Administration (NASA) scientist, Jesse Tarnas, therefore, the best chance of habitat inMarsto live is underground.
“If this planet contains water, then there is a good chance for life there,” he said.
