I was privileged to be on the team of citizen scientists that mapped Bennu looking of a safe place to collect the sample. I marked every boulder, rock, pebble, and crater on over 700 images over a period of several months. It's great to finally get to see some of the science results. Thank you for making this video Dr Lieu. And a quick shout-out to all of the other Bennu Mappers!

120 g is twice the planned minimum, but a lot lower than the 2+ kg maximum we were "expecting." When I saw the sampling vid, I was hopeful we'd gotten way more than we were planning on (closer to the upper end). When I heard that the TAGSAM flap was stuck open and stuff was leaking out, I got anxious (closer to the lower end). BLUF: I'm MORE than happy with 120 g after mapping all those rocks.

120g is just massive compared to the Hayabusa ones though - and i know they have gotten so much out of it in terms of science.

Well most people don't know that if you put the other crews in and turn them in just snug you can get the other tight crews out. And it sounds like Bennu's gravity collected shattered rocks and they did not shatter on Bennu.

Just found your channel. Subbed. Excellent content, good editing, informative to us "laymen".

No rocket scientist here, but incredibly well versed in stainless fasteners. My guess is. The bolts were assembled dry and utterly clean to prevent possible contamination. Stainless in any commonly used alloy is virtually impossible to remove with 100% reliably. Over torqued fasteners up the risk of galling exponentially. Typically a nickle based never seize product is used on the threads. PTFE is virtually worthless in this application. Stainless is incredibly tough and tenacious but not a very high surface hardness. Much less than carbon steel. Any deformation in the threads causes galling at the point of contact under pressure. Even spinning a nut to fast will gall the treads. So my theory is the bolts galled due to lack of lubrication. But obviously lubrication could contaminate a sample. Just a passing thought.

Love all the b roll of them working on it. Haven't seen much of that elsewhere.

Thank you for the update, Dr. Lieu. Fascinating stuff. The much deeper penetration into Bennu by the sampling device than was expected was a case of serendipity; the sample is likely to be more pristine than surface material exposed to the solar wind. Imagine being able to examine material derived from the dust in the original solar nebula more than 4.5 billion years ago! Exciting times ahead!

The aggregation of nature truly knows no bounds. While your standard volumetric or exponential measurement is easy to calculate, but once you start factoring in condensed matter, it no longer is a volume but one that contains surface area. One of the functions of the universe in my estimation; among others like the sequestration of heat, magnetism, plasma, and consciousness. Our geological missions are the only ones that will yield physical evidence, often the gold standard in science, and the sooner that happens the sooner we will understand the palette of this cold welding.

I wonder if they couldn't use anti-seize coating on the fasters because of contamination issues as well - no easy way around it except by using dissimilar materials next time.

Cold welding doesn't happen just in space it happens here on Earth in a vacuum, also the two pieces need pristine surfaces ie no oxidation layers on the surfaces to be joined.

I wonder if any asteroid samples could be tied back to a planetary impact or a likely planet it might have come from by impact ejection, rather than being the primordial rock that formed x-planet? Many asteroids are formed by collections of smaller “rock” debris.
