"OSIRIS-REx Unveils Asteroid Treasure Trove"

NASA's OSIRIS-REx mission successfully removed the last two screws from the end of its arm, revealing a "treasure trove of asteroid material" from the near-Earth asteroid Bennu, including rocks nearly half an inch in diameter. The newly accessed sample, which has yet to be weighed, adds to the 2.48 ounces of material collected prior to the lid being removed, surpassing the mission's minimum goal of 2.12 ounces. Custom instruments made from surgical stainless steel were developed to remove the stubborn screws, and the curation team is now working to transfer the sample into trays for further analysis and storage.
