NASA's OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) probe made history on October 20, 2020, when it landed on Bennu, a 1,640-foot (500 meters) tall asteroid that lies 200 million miles away from Earth. The brief, six-second touchdown was planned to retrieve samples of the ancient space rock's surface and bring them back to Earth for analysis.
