Taken on March 28 from a distance of just 3.4 kilometers (2.1 miles) the field of view is about 50 meters across while the light colored boulder at top right is 4.8 meters tall. Likely a loose conglomerate rubble pile asteroid, Bennu itself [7] spans less than 500 meters. That's about the height of the Empire State Building. Mapping the near Earth [8] asteroid since the spacecraft's arrival in December of 2018, the OSIRIS-REx mission [9] 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.
