Perseverance Mars rover finds surprising volcanic rocks in once lake-filled crater
's deep subsurface, where the oxidation of iron through interactions with water can produce molecular hydrogen and hydrocarbons such as methane that can act as the building blocks of some of life's more complex compounds.
In a second paper, led by Svein-Erik Hamran, a professor of remote sensing at the University of Oslo, Norway, results from Perseverance's ground-penetrating radar show that the entire geological unit containing Séítah and Máaz extends underground and has been partially uplifted, placing it at an angle.
The lake filled Jezero sometime after Séítah and Máaz formed, covering them with mud that ultimately formed a deep layer of sedimentary rock. But as, the lake dried up, exposing the sediment."Since then, it's been sitting there being eroded, mostly by wind," Farley said."Three-and-a-half billion years' worth of blowing sand can really sculpt a landscape."
