After an amazing journey, a grain from the asteroid Bennu will be brought to Diamond Light Source, the UK’s national synchrotron, for scientific measurements. The grain is from 100 milligrams of sample sent to the Natual History Museum (NHM) in London, a small fraction of the approximately 70 grams of Bennu rock and dust brought back by NASA’s OSIRIS-REx mission. It will be subject to intensive analysis at the Dual Imaging And Diffraction (DIAD) instrument in Diamond by Dr. Ashley King and his team from the NHM and other OSIRIS-REx collaborators at the Open, Oxford and Manchester Universities.
