On Wednesday (Jan. 10), NASA technicians finally removed the stuck fasteners from the sample return capsule of its OSIRIS-REx spacecraft — which completed the first asteroid sample return mission in U.S. history when it landed in Utah in September 2023. Tucked in its capsule were rocks and dust collected from the asteroid Bennu. Initially, the team at NASA's Johnson Space Center in Houston, Texas was able to access 70.3 grams (2.48 ounces) of material — 10 grams more than the mission’s goal — from the outside of the sampler head, called the Touch-and-Go Sample Acquisition Mechanism (TAGSAM).
However, the bulk of the asteroid sample material remained trapped inside the capsule when two of the 35 fasteners on TAGSAM could not be removed with existing tools approved for use inside the OSIRIS-REx glovebox, which ensures the asteroid samples are not contaminated during processing. Thankfully, researchers were able to develop new tools that could tackle the stubborn fasteners, according to a statement from NASA.
