Engineers succeed in releasing two fasteners that blocked access to OSIRIS-REx Bennu samples
Using new specially designed tools, engineers have finally succeeded in removing the two fasteners that had prevented them from opening the sample return capsule that holds the bulk of material from the asteroid Bennu that was grabbed by OSIRIS-REx and brought back to Earth.
Curation processors paused disassembly of the TAGSAM head hardware in mid-October after they discovered that two of the 35 fasteners could not be removed with the tools approved for use inside the OSIRIS-REx glovebox.
In response, two new multi-part tools were designed and fabricated to support further disassembly of the TAGSAM head. These tools include newly custom-fabricated bits made from a specific grade of surgical, non-magnetic stainless steel; the hardest metal approved for use in the pristine curation gloveboxes.
The fasterners have been removed, but the sample capsule still needs to be dissassembled before the samples can be accessed and analyzed. It is now expected that by the spring the material will be fully catelogued and available for scientists to study.
In an ironic twist, OSIRIS-REx brought back so much extra material clinging to the outside of that sample return capsule that such research has already begun. In fact, that extra material actually exceeded in weight the minimum amount the mission wanted to capture inside the capsule. What will be found inside the capsule will only add to the mission’s success.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
