OSIRIS-REx brought home twice as much material from Bennu than planned

Curators cataloging the material returned by OSIRIS-REx’s sample capsule from the asteroid Bennu have now completed weighing the material,l and have discovered that the spacecraft grabbed more than twice as much material from Bennu as planned.
NASA’s OSIRIS-REx spacecraft delivered 4.29 ounces (121.6 grams) of material from asteroid Bennu when it returned to Earth on Sep. 24, 2023; the largest asteroid sample ever collected in space and over twice the mission’s requirement. The mission team needed at least 60 grams of material to meet the mission’s science goals, an amount that had already been exceeded before the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) head was completely opened.
More than 60 grams were recovered outside the capsule that had stuck to it during touch-and-go operations. Once they were able to open the capsule and weigh the material inside, they found it had captured as much stuff, so that in total the mission brought back a double complement of material.
This material will now be distributed to scientists worldwide for study. It is likely that it will overturn almost all assumptions presently held about the make-up of the solar system’s asteroid population, since previous to the recent asteroid sample return missions of OSIRIS-REx and Japan’s Hayabusa-2 our only samples came from material that survived after burning through the Earth’s atmosphere. That journey resulted in an incomplete and biased census, with the most delicate material destroyed.
Readers!
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.

Minor edit in second paragraph: “Once they were able to open the capsule and weigh the material inside, they found it had captured twice as much stuff as needed.” (or something like that)
Andi: Thank you. I have rewritten to clarify.
I wonder what the sample smells like.
“The smells of space”
“What do walnuts, brake pads and burnt steak have in common? According to astronauts, they all smell like space. While each astronaut smells something a bit different, they all agree ‘space stinks’.”
