The Mars Perseverance rover has detected intact organic molecules near previously described potential signatures of ancient life, according to a new study published today in Science Advances. Perseverance has been exploring Mars’s Jezero Crater since 2021, giving scientists insight into the Red Planet’s geology and searching for potential signatures of life. Billions of years ago, Jezero Crater was frequently flooded with water, making it a potentially hospitable place for ancient microbial life.
