When NASA's Perseverance satellite revealed The Mars rover started studying the rocks in Jezero Crater.
Instead of being the result of volcanic activity at the surface, the crater's bottom appeared to be made of rocks that were produced deep down.
The Perseverance rover's timeline of the planet's geology and water history will be available.
But it will take ten years before the samples from the red planet can be brought back.

Four studies that were published in the journal Science provide documentation for the findings.
For NASA's 2020 Mars Exploration Mission, the Jezero Crater, which is located north of the Martian equator, was a key objective.
