OSIRIS-REx Leaves its Mark on Bennu

The transcript describes the spacecraft's mission on asteroid Bennu, highlighting the final flyover on April 7th, 2021, which revealed the aftermath of the sample collection event from October 20th, 2020. During this event, the spacecraft's sampling head penetrated the asteroid's surface, collecting material with a nitrogen gas charge. The thrusters' action displaced boulders, forming a ring-like shape. The spacecraft will remain near Bennu until its departure on May 10th, 2021, beginning a two-year journey back to Earth, with the sample expected to arrive on September 24th, 2023.
