OSIRIS-REx tagging Bennu

Please accept marketing-cookies to watch this video.

In mid-2020, the OSIRIS-REx spacecraft will use its TAGSAM (Touch-and-Go Sample Acquisition Mechanism) device to stir up and collect a sample of loose material from asteroid Bennu’s surface. That material, which may contain organic molecules that are the precursors to life in the Solar System, will be returned to Earth for study in 2023.
