@leoalbuq1 Great Question! Most Lunar Samples Brought Back to Earth by Apollo Astronauts ... - Latest Tweet by NASA

Great question! Most lunar samples brought back to Earth by Apollo astronauts have been opened and studied. But some samples collected on the Apollo 15, 16 & 17 missions were kept unopened and pristine, so they could be analyzed with more advanced technologies available today.— NASA (@NASA) March 4, 2022
