This three-dimensional view of asteroid Bennu was created by the @osiris_rex Laser Altimeter (OLA), contributed by the @canadianspaceagency , on NASA’s OSIRIS-REx spacecraft from Feb. 12 through 17.
OLA obtained these measurements by firing laser pulses at Bennu and measuring the amount of time it takes for the light to bounce off the asteroid’s surface and return to the instrument. Using this data, the OLA team created the 3-D model of Bennu’s surface.
