Recent findings from NASA's Perseverance rover suggest the possible presence of organic molecules and mineral patterns indicative of past microbial life on Mars. While not conclusive, these discoveries represent a significant step in the search for extraterrestrial life.
NASA's Perseverance rover has identified intriguing features on Martian rocks within Jezero Crater that could be "vital imprints," potentially signaling past life. These features are linked to reactions between clay minerals and organic substances, a process often associated with biological activity on Earth, according to Joel Horwitz, a key researcher involved in the NASA study.
Specifically, Perseverance has detected the presence of Vivianite and Griegite. Vivianite, a blue iron phosphate mineral, is commonly found on Earth in sediments, peat swamps, and areas with decaying organic matter.Griegite, an iron sulfide mineral, can be produced by microbial activity.
