Seven articles published in the magazines “Nature”, “Nature Astronomy”, “Nature Geoscience” and “Nature Communications” report a series of research results about asteroid Bennu. Hundreds of scientists used data gathered by NASA’s OSIRIS-REx space probe to study in particular various aspects of Bennu’s geology. The results will be useful in various other studies, from those about the origin of life’s building blocks that sowed the Earth to those about the solar system’s formation, including some practical ones such as the search for an area on which OSIRIS-REx can descend to take samples to assessments of the danger posed by asteroids such as Bennu.
