Like boot prints on the Moon, NASA's OSIRIS-REx spacecraft left its mark on asteroid Bennu. Now, new images — taken during the spacecraft's final fly-over on April 7, 2021 — reveal the aftermath of the historic Touch-and-Go (TAG) sample acquisition event from October 20th, 2020.

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 (marked with a red "X" in the second of these two images) and agitated dust and boulders on the surface.

The Nightingale sample site after the TAG event. The red "X" indicates the approximate location where OSIRIS-REx contacted the asteroid's surface. The red circle shows the same boulder that was circled in the before image.
