This last week the OSIRIS-REx spacecraft continued its approach toward Bennu. Now that we have visually acquired the asteroid, the PolyCam camera images Bennu three times a week to provide data to the navigation team. At a distance of 1.1 million km, Bennu appears as just a dot. However, the navigation team can still use these images to calculate the spacecraft trajectory and refine Bennu’s orbit.
