101955 Bennu (provisional designation 1999 RQ 36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table and has the highest cumulative rating on the Palermo Technical Impact Hazard Scale. [9]
During this “TAG event,” the spacecraft’s arm sank far deeper into the asteroid than expected, confirming that Bennu’s surface is incredibly weak. Now, scientists have used data from OSIRIS-REx to revisit the TAG event and better understand how Bennu’s loose upper layers are held together.
The Regolith X-ray Imaging Spectrometer (REXIS) provided an X-ray spectroscopy map of Bennu to map element abundances. [97] REXIS was a collaborative development by four groups within Massachusetts Institute of Technology (MIT) and Harvard University, with the potential to involve more than 100 students throughout the process. REXIS was based ...
The spacecraft launched on September 8, 2016 and arrived at Bennu in December 2018. After mapping the asteroid for almost two years, it collected a sample from the surface on October 20, 2020. The ...
As OSIRIS-REx, the spacecraft spent seven years on a round trip to the near-Earth asteroid Bennu, which included time spent surveying, touching down on and collecting a sample from the space rock.

Asteroid 101955 Bennu is a B-type asteroid which is the target of the OSIRIS-REx mission. The mission seeks to characterize the asteroid by mapping the surface, studying the Yarkovsky effect, and retrieving a sample of the asteroid to return in 2023. The spacecraft was launched in 2016 and has been at Bennu since December 2018.
NORAD used an official map that was updated consistently to show where he was. NORAD, the agency responsible for monitoring and defending airspaces over the United States and Canada, has tracked ...
