Bennu itself spans less than 500 meters. That's about the height of the Empire State Building. Mapping the near Earth asteroid since the spacecraft's arrival in December of 2018, the OSIRIS-REx mission plans a TAG (Touch-and-Go) maneuver for July 2020 to sample Bennu's rugged surface, returning the sample to planet Earth in September 2023. Citizen scientists have been invited to help choose the sample collection site.
