The Mars rover found signs liquid water once ran through rocks made by volcanoes.
, the site of an ancient meteor impact where the rover touched down just north of the Martian equator. The planet was at one time home to an abundance of lava flows and rocks that, with the presence of water, could have sustained ancient life.
And they found it sooner rather than later: One of Perseverance’s most exciting discoveries revealed that the floor of the Jezero crater is home to a substantial amount of igneous rocks, stones that can only be formed by the cooling and solidification of molten liquid magma. In essence, volcanic activity may have been a more important process in that part of Mars than scientists previously thought.
As the rover also found evidence of large amounts of olivine on the surface, its presence could signal that the mineral is just as widespread in other regions beyond Jezero crater. In such a case, researchers note that this olivine-enriched ground could beThe Mars rover’s circuitous path through Jezero Crater, showing Perseverance’s location and the Ingenuity helicopter , as well as named regions.
