They treated the landscape as a template for Mars and examined the organic matter preserved in rock deposits nearby. If these iron-rich minerals harbour traces of life on Earth, then they may hold clues to past microbial life on the red planet. Previous missions to find traces of life have used heat to inspect rock for the presence of organic matter. However, heating goethite or hematite does not destroy any organic matter that is there, meaning these minerals could be good life-search targets. “We have yet to find convincing traces of organic matter that would indicate previous life on the red planet,” Sephton said.
