OSIRIS-REx’s sampling arm imaged above the surface of asteroid Bennu from a distance of 70 meters on April 14, 2020.
(From the OSIRIS-REx mission site)
Captured on April 14, 2020, this image shows the OSIRIS-REx spacecraft’s sampling arm – called the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) – and asteroid Bennu during the mission’s Checkpoint Rehearsal.

The image was taken by the SamCam camera on NASA’s OSIRIS-REx spacecraft on April 14 from a distance of 230 ft (70 m), which is the closest image of Bennu captured to-date. The field of view is 79 ft (24 m). For reference, the bright, rectangular boulder on the crater’s south rim (lower left) is 7.5 ft (2.3 m) long, which is about the size of a door. The TAGSAM head is 1 ft (0.3 m) wide.
