Witness Plates and TAGSAM Head Inspection
Curation researchers eliminated 14 circular witness plates from the top of the TAGSAM head on Monday andTuesday These plates were utilized to keep an eye on interior ecological conditions of the spacecraft at different points throughout the objective and were thoroughly included and kept away for contamination understanding.
After eliminating all 14 plates and gathering any staying loose dust, the group eliminated the TAGSAM head from its avionics deck platform and had the very first chance to see the 24 surface area contact pads on the bottom of the head and the asteroid sample below the collector head.

Unveiling the Asteroid Material
When the sample collector touched the asteroid in October 2020, these surface area contact pads caught fine-grained asteroid rocks and dust straight from Bennu’s surface area layer. The products in the contact pads will offer a distinct set of samples that will inform researchers about the conditions at the really surface area of Bennu.
The asteroid product on and interior to the capture ring– the protected base into which the TAGSAM was seated when stowed– originated from the sample collection occasion. During collection, TAGSAM shot nitrogen gas at Bennu to press asteroid particles from as deep as 19 inches (50 cm) listed below the surface area into the TAGSAM head, which sealed with a flap. If gathered particles held that flap open, they would fall out into the location interior to the capture ring.
Scientific Implications of the Collected Material
These 2 sets of gathered products will hence provide researchers details about the surface area product and product at higher depths listed below the surface area. Altogether, these fine-grained samples from the asteroid will assist researchers and scientists make brand-new discoveries about the geologic history of asteroid Bennu, its effect history, and ramifications for asteroid effect evaluation.
