OSIRIS-REx's TAGSAM Head

SamCam Images TAGSAM in Flight

This image shows the OSIRIS-REx Touch-and-Go Sample Acquisition Mechanism (TAGSAM) sampling head extended from the spacecraft at the end of the TAGSAM arm. The image was obtained by the SamCam camera on November 14, 2018 as part of a visual checkout of the spacecraft’s sample acquisition system. This is a rehearsal image for an observation that will be taken after TAG to help document the asteroid material collected in the TAGSAM head. The TAGSAM system was developed by Lockheed Martin Space to acquire a sample of asteroid material in a low-gravity environment.

There are two witness plate assemblies on the top perimeter of the TAGSAM head, one of which is entirely visible in this image. These witness plates record the deposition of material on the TAGSAM head over the duration of the mission, giving scientists a record of material on the TAGSAM head that is not from Bennu.
