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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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’.”
