NASA’s OSIRIS-REx Mission Rehearses Retrieval Of Asteroid Sample Capsule

Recovery teams simulate field operations for the safe recovery of fragments from asteroid Bennu


To the casual passerby, NASA scientists gingerly examining a flying saucer-shaped object in the desert may be a cause for questions.

However, the team behind NASA’s OSIRIS-REx mission is preparing for a manmade object to return to Earth.

Mission members have this month been rehearsing recovering a mock sample return capsule from the location where the real one, with fragments of asteroid Bennu, will land on Sept. 24 in the Utah desert.


If everything goes according to plan, OSIRIS-REx’s sample return capsule will separate from the spacecraft, enter the atmosphere and parachute safely to Earth for recovery.

Though the team has rehearsed portions of the recovery operation many times this year, this was the most realistic rehearsal yet, taking place at the Department of Defense’s Utah Test and Training Range about 80 miles Southwest of Salt Lake City.

Besides taking place at the real landing location, the rehearsal included helicopter training for the OSIRIS-REx team members who will fly by helicopter to retrieve the sample capsule from its landing site inside a 36-mile by 8.5-mile ellipse on the military range.

Rocks and dust, called regolith, were collected from Bennu’s surface in 2020.

NASA explains: “Bennu is likely to be a well-preserved, 4.5 billion-year-old remanent of the early solar system, so the samples should provide insight into the role that similar asteroids played in the formation of planets and the delivery of organic material and water to Earth that may have ultimately led to life.”

Data collected from the OSIRIS-REx mission will also help scientists better understand asteroids that could impact Earth and inform future asteroid deflection efforts.

To investigate these questions, scientists must carefully preserve, protect, and handle the asteroid samples, which will be examined and stored in a new curation facility managed by NASA’s Astromaterials Research and Exploration Science division, or ARES, at Johnson Space Center in Texas.

The division is home to the world’s most extensive collection of extraterrestrial materials – including lunar rocks, solar wind particles, meteorites, and comet samples.
