The Frontline Impact

How this affects you

Data from the OSIRIS-REx mission indicates the surface of asteroid Bennu has measurable spectral heterogeneity, with variations in hydration indicators and silicate band positions between different sampling sites. This provides a remote sensing baseline for future laboratory analysis of samples from Bennu.
