Nightingale Site Before and After TAG

Bennu’s surface was disturbed in three different ways: by the force of the spacecraft touching down; by the sampling mechanism, which collected material by blowing gas into its collection filter; and by four of the spacecraft’s back-away thrusters, which moved the spacecraft away from the sample site and agitated dust and boulders on the surface. The image above shows the TAG site and highlights a large boulder thrown about 40 feet (about 12 meters).
