Bits of Bennu Float from OSIRIS-REx's Sample Head Rocks and dust from asteroid Bennu leak from the TAGSAM sample head aboard NASA's OSIRIS-REx spacecraft on 22 October 2020. The spacecraft collected so much material that the head's Mylar flap did not fully close. The mission team decided to forgo efforts to weigh the sample and instead stow it as quickly as possible.
