According to a study published in the journal Geology, researchers discovered the place on Mars that could have been the last habitable place on this planet.
They found a 18-square-mile deposit of chloride salt located in the planet’s Meridiani region near the Mars Opportunity rover’s landing site.
Based on the digital terrain mapping and mineralogical analysis of the features surrounding the deposit, it has been concluded that it is about 3.6 billion years old.
It is believed that salt deposits are evidence of evaporated bodies of water.
Research associate Brian Hynek stated that this latest discovery is one of the last examples of a sizeable lake on Mars.
Researchers used the extent and thickness of the salt to conclude that this lake was less salty than the Earth’s oceans. Because of this, it could have been friendly to microbial life.
