“Surprised” scientists have discovered that the Sun’s heat likely fractures rocks on asteroid Bennu in only 10,000-100,000 years, an advance suggesting space rocks age more rapidly than earlier thought.

High-resolution images of rock fractures on asteroid Bennu taken by the Osiris-Rex spacecraft were analysed by researchers, said the study, published recently in the journal Nature Geoscience.

The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (Osiris-Rex) spacecraft left Bennu’s orbit in May 2021 and is expected to reach Earth in the latter half of 2023.
