Quoting NASA, it’s a “large amount!” The spacecraft captured images of the sample collector head as it moved through several different positions. They came to this conclusion after comparing images of the empty collector head with Oct. 22 images of the TAGSAM head after the sample collection event. The OSIRIS-Rex team will now focus on stowing the sample in the Sample Return Capsule (SRC), where any loose material will be kept safe during the spacecraft’s journey back to Earth. Newly available analyses show that the collector head was flush with Bennu’s surface when it made contact and when a nitrogen gas bottle was fired to stir surface material. All data so far suggest that the collector head is holding much more than two ounces of regolith.
