Curating the Asteroid Sample
One of the goals of the OSIRIS-REx mission was to collect at least 60 grams of asteroid material. The total sample that the spacecraft delivered to Earth was 4.29 ounces (121.6 grams). Curation experts at NASA's Johnson Space Center, working in new clean rooms built especially for the mission, discovered bonus asteroid material covering the outside of the collector head, canister lid, and base. There was so much extra material, it slowed down the careful process of collecting and containing the primary sample.

On May 10, 2021, NASA's OSIRIS-REx spacecraft said farewell to asteroid Bennu and began its journey back to Earth with the precious material it collected from the asteroid. The spacecraft successfully delivered the sample of Bennu on Sept. 24, 2023, with its sample return capsule landing at 8:52 a.m. MDT (10:52 a.m. EDT) in a targeted area of the Department of Defense's Utah Test and Training Range near Salt Lake City, Utah.

On Oct. 20, 2020, NASA's OSIRIS-REx spacecraft successfully touched the surface of the near-Earth asteroid Bennu and collected abundant material during the Touch-and-Go (TAG) sample collection event. The sampling event brought the spacecraft all the way down to sample site Nightingale, touching down within 3 feet (1 meter) of the targeted location.

NASA's OSIRIS-REx spacecraft completed its 1.2 billion-mile (2 billion-kilometer) journey to arrive at asteroid Bennu on Dec. 3, 2018. The spacecraft executed a maneuver that transitioned it from flying toward Bennu to operating around the asteroid.
Read MoreEvening Launch for OSIRIS-REx
An Atlas V rocket traced a blazing arc into the Florida sky on Sept. 8, 2016, sending a small robotic explorer called OSIRIS-REx on its way to an asteroid. Scientists anticipate the mission will help us to better understand the early solar system, as well as the hazards and resources of near-Earth space.
