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]
While researchers suspect that Bennu was too small to host water, the hydroxyl groups may have come from water present in its parent body before Bennu split off. [ 42 ] [ 43 ] OSIRIS-REx entered orbit around Bennu on 31 December 2018 at about 1.75 km (1.09 mi) to start its extensive remote mapping and sensing campaign for the selection of a ...
TAGSAM is a robotic arm attached to the main body of the spacecraft that collects a sample from the asteroid, and puts the samples into the Earth return vehicle. [5] Bennu is about 500 meters in diameter and has very low gravity, so the arm must perform the collection in near zero gravity, yet still contend with some gravitational forces from the asteroid.

Apophis is of interest because it’s an S-type, or stony, asteroid — different from other space rocks visited by NASA missions, including Bennu, which is a C-type, or carbonaceous, asteroid.
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.
Selena Gomez and Benny Blanco had a cozy, cuddly Thanksgiving.. On Thursday, Nov. 28, Gomez, 32, shared a photo to her Instagram Stories of her boyfriend of more than one year, Blanco, 36 ...
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.
