What Did The Gale Crater Keep As A Secret?

At Gale Crater, the Curiosity rover has helped put together the tale of what happened there. There was a lot of water in the area for an extended period, forming a long-standing lake and groundwater. The lake and underlying water were found to be hospitable to bacteria based on mineral and chemical readings.
It is possible that microorganisms once utilized nutrients, chemical compounds, and energy sources found in lakebed drill samples. Life might have thrived even in the deepest reaches of the Earth’s crust if water had flowed through fissures in the rock. Some strata’s composition also makes them suitable for retaining possible traces of previous life.
