These measurements may reveal insights into the origins of life in our solar system
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 the 100 milligrams of sample sent to the Natural History Museum (NHM) in London, a small fraction of the approximately 70 grams of Bennu rock and dust brought back by NASA’s (National Aeronautics and Space Administration, USA) 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.
The DIAD beamline at Diamond is a ‘one of a kind’ scientific instrument that can extract chemical composition information and enable virtual dissection at an unprecedented level of detail, non-destructively. This will provide a wealth of scientific data and new knowledge about the asteroid, and the origins of our solar system.
The Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer, or OSIRIS-REx, spacecraft launched to the near-Earth asteroid, Bennu on Sept. 8, 2016. In October 2020 it collected a sample of rocks and dust from its surface 330 million km (205 million miles) from Earth. The material, collected by the NASA mission, took almost three years to be returned to Earth (Utah desert, US) this Sept. 24, 2023.
