The Red Planet may be home to a much more complex geochemical cycle than originally suspected.
in the crater that could hold more clues to former Martian life.
Organic compounds are the building blocks of life. They are molecules composed of the element carbon and often have other elements such as nitrogen, oxygen, hydrogen, phosphorus, and sulfur. Several types of have been detected in meteorites that blasted away from Mars and landed on Earth, and in Mars’ Gale Crater. on the Red Planet include water-rock interactions or deposits on the surface of the planet through space dusts or meteors. The team notes that the “key building blocks for life may have been present over an extended period of time,” making this area of Jezero crater “potentially habitable.
“As planetary scientists and astrobiologists, we are very careful with laying out claims—claiming that life is the source of organics or possible biosignatures is a last-resort hypothesis, meaning we would need to rule out any non-biological source of origin,” study co-author and CalTech planetary scientist Sunanda Sharma
