The sample collection process was a carefully orchestrated dance. OSIRIS-REx extended its 2 meter (6.6 foot) TAGSAM robotic arm with the 30 cm (1 foot) wide sampling head attached, while folding in its solar panels to protect them. The probe then slowly approached the surface, eventually touching down to within a single meter (3.3 feet) of the selected target. The entire process was monitored by the SamCam imaging camera mounted above the arm.
The camera shows the TAGSAM head approaching and then impacting Bennu’s surface at just 0.2 mph, penetrating in to the regolith. At first, it appears to crush some
