On 11 August, the OSIRIS-REx spacecraft conducted a practice approach to the asteroid Bennu that brought it to a point approximately 40 m (~130 ft) above the surface. It then performed a back-away burn. These images used to make this video were captured over a 13.5-minute period. The first was taken at an altitude of about 128 m. The last was taken at around 44 m. OSIRIS-REx will make landings on Bennu and collect sample to be returned to Earth.
