The first in-depth study of a sample from the asteroid Bennu has revealed the presence of life-forming ingredients. Scientists examining the sample found the rare astromaterial magnesium phosphate in a surprising quantity along with glycine, an amino acid that makes up protein. Minerals like carbonates, sulfites, olivine, and magnetite have also been detected, indicating a watery past of Bennu’s parent body. NASA’s OSIRIS-REx mission chose Bennu due to its pristine state, offering a window into the early solar system. Moreover, with a potential impact threat to Earth in 2182, understanding Bennu’s composition becomes crucial. The recent findings at the Lunar and Planetary Science Conference suggest water-bearing minerals and water-altered compounds that may have influenced the early Earth’s development. Lead investigator Jessica Barnes believes these discoveries could unveil geologic activities on Bennu’s parent body, shedding light on its fascinating history.
