Past the Mission Objectives: How NASA Surpassed Expectations With Asteroid Bennu

NASA’s OSIRIS-REx spacecraft delivered an unprecedented 4.29 ounces of asteroid Bennu materials to Earth, surpassing its mission targets. Regardless of preliminary challenges, the pattern was efficiently secured for future scientific analysis, guaranteeing a legacy of worldwide collaboration and examine of the photo voltaic system’s origins.

NASA’s OSIRIS-REx spacecraft delivered 4.29 ounces (121.6 grams) of materials from asteroid Bennu when it returned to Earth on September 24, 2023; the most important asteroid pattern ever collected in house and over twice the mission’s requirement.

Exceeding Expectations Early On

The mission crew wanted not less than 60 grams of fabric to satisfy the mission’s science targets, an quantity that had already been exceeded earlier than the Contact-and-Go Pattern Acquisition Mechanism (TAGSAM) head was utterly opened. In October 2023, curation processors from the Astromaterials Analysis and Exploration Science (ARES) division at NASA’s Johnson House Heart in Houston have been capable of accumulate small rocks and dirt from inside the massive canister that housed the TAGSAM head, in addition to from contained in the TAGSAM head itself via the pinnacle’s mylar flap.

Overcoming Challenges

Disassembly of the TAGSAM head was paused in late October 2023, when the crew encountered two cussed fasteners protecting them from having the ability to full the method to disclose the ultimate pattern inside.

After designing, producing, and testing new instruments, the ARES curation engineers efficiently eliminated the fasteners in January and accomplished disassembly of the TAGSAM head. The remaining Bennu pattern was revealed and punctiliously poured into wedge-shaped containers. 1.81 ounces (51.2 grams) have been collected from this pour. Mixed with the beforehand measured 2.48 ounces (70.3 grams) and extra particles collected outdoors of the pour, the majority Bennu pattern mass totals 4.29 ounces (121.6 grams).

Securing a Legacy for Future Analysis

NASA will protect not less than 70% of the pattern at Johnson for additional analysis by scientists worldwide, together with future generations.

From NASA Johnson’s repository, the Bennu materials shall be containerized and distributed for researchers to check. As a part of the OSIRIS-REx mission, a cohort of greater than 200 scientists world wide will discover the regolith’s properties, together with researchers from many US establishments, NASA companions JAXA (Japan Aerospace Exploration Company) and CSA (Canadian House Company), and extra.

Later this spring, the curation crew will launch a catalog of the OSIRIS-REx samples, which is able to make the asteroid pattern accessible for request by the worldwide scientific neighborhood.
