2019-08-29 – This 3D global map of asteroid Bennu’s topography was created from about 20 million measurements taken by the OSIRIS-REx Laser Altimeter (OLA), an instrument contributed to the international sample-return mission by the Canadian Space Agency. The colours represent the distance from the centre of Bennu: dark blue areas lie approximately 60 metres lower than peaks indicated in red. This model has a resolution of approximately one measurement per metre.
