What has NASA's OSIRIS-REx discovered around the asteroid Bennu?

The video discusses the OSIRIS-REx mission to asteroid Bennu, highlighting its unique orbit and mapping efforts. The mission aims to collect a pristine sample from Bennu's surface, providing insights into the asteroid's composition and history. Initial findings reveal unexpected hydrated materials and dynamic activity, including ejection events and a gradual increase in rotation speed due to the YORP effect. The mission faces challenges in selecting safe landing sites due to Bennu's boulder-covered surface. Future steps include finalizing the sample collection site and executing the collection maneuver.
