Great presentation Simon, thank you. I was fortunate enough to be part of the citizen science team that mapped Bennu to find a suitable sample acquisition site. I counted and marked every pebble, rock, boulder, and crater on over 700 images. It was slow, tedious work that took nearly 6 months, but I'm very glad that I participated. I'm really looking forward to the return of the sample and all the science we get from it.
That's excellent. It may be unlikely, but just imagine the feeling you'd get if one of the pebbles you'd remotely mapped should happen to be part of the sample returned and entered into the Scientific Record. To know there's a piece of mineral that you mapped out from such a distance, now sitting in a vault here or, even better, on public view. Photographed, studied and enjoyed, but in the knowledge that you or some other human being had first seen and measured that same item in situ.
@@bikkies That would be cool. NASA initially chose 4 candidate sites for the sample return, I learned that the site that my photos came from was called Kingfisher, and in the end, the site that was chosen was Nightingale. So unfortunately none of the pebbles that I took so long squinting at will be returning to earth. It was still a great thing to be a part of though, and I'm really glad that I participated. I still have all 700+ images in a folder on my computer, so if I'm ever feeling nostalgic about rocks...
Say it with me: EFF BENNU! ^_^
Space is fake...Research flat earth👍
It never stops amazing me how scientists come up with these elegant but precise names.
Really fascinating and enjoyable video Simon. Well done to you and your team

Thanks for pluggin the little guy. So much information to be had. Great mission!
I wonder what percentage of NASA's budget is designated for coming up with the acronyms for their probes and programs?
One _Million_ dollars🧏🏻♂️
@@w13rdguy times 10^4
You know they have a whole division just for that.
Doesn't the Hayabusa deserve it's own Megaprojects video?
You forgot to mention that the sample was so large that it had jammed the lid open on the return container. They finally managed to get it closed by "jiggleing" the container to clear the seals.
OSIRIS-REX has been worth the cost already. i'll have a tight feeling in the pit of my stomach until that parachute opens. After the length of this journey, i bet the engineers do to! Breathe deeply, it's going to be fine. Repeat !:-)
The fact that I found the idea of Americans abandoning the Imperial system in 200 years and weighing things in Shaq's, and the fact that I can see this happening in a weird timeline, funny as hell, proves spending 2 years in my house with nothing but unregulated online access maybe wasn't as good to my sense of humor then I thought. . .
Evidently, it wasn’t conducive to your understanding of the correct usage of apostrophes. Having said that, your point is well taken and I think your comment is funny, hence my upvote. I’m sorry for being a douchebag, btw. I just couldn’t help myself.
@@jessejoyce1295 we're assholes to our core. It's ok. They're jealous of the swinging action betwixt our legs. 😁😝🤘🇺🇲
Nah it's funny
Yes we will switch to shaqs for weight and Peter Dinklage's for lengths we were thinking about Michael J foxes but couldn't be measured with enough reliability we will also switch liquid measuring to Pamela's Andersons breast cup size which will be known as p-cup roughly equivalent to 2 liters and instead of quarter cup size it will be the Jordan nut size !!! 😆 🤣 😂 😹 😆 🤣 😂
When you’re the country with the greatest space program ever known, you can weight things in shaqs if you want.
I vote that we keep the Shaq system lol
Well done on this I really enjoyed the content!
The Shaq system... Brilliant!
I'm glad global space agencies have at last started working on ways to deflect mass extinction events striking our planet. I'm surprised it took until 2014 to start looking into it.
One of the most interesting videos I've ever seen.
Wouldn’t it be ironic if the Osiris-Res mission was the cause of the slight change in orbit that causes a collision with Earth.
It's a lot easier to blow it up at least.
@@whom382 Scott Manley has a good video on blowing up asteroid like this and how it doesn't make that much difference in a lot of ways.
Hello and Good Morning Simon
Sometimes with all the craziness and superstition you forget just how far we have come and what we are capable of when we cooperate in a common effort. Amazing.
14:00 That's good then. Even if it hit Earth it would mostly break up and be vaporized in the atmosphere. And Long before that we could break it apart into its relatively small harmless components.
As I watch this right now, the sample has made it back safely to earth!!!!!!!!!
I desperately want asteroid mining to get going so that we can get golden bullets normalized.
For context, lead is used in bullets because it's soft which allows it to be engaged by rifling without damaging the barrel while at the same time being heavy which allows it to retain and deliver the maximum amount of kinetic energy to the target.
...you know what else is extremely heavy but also soft? 24 carat gold...
I mean if you really think about it gold being so cost prohibitive is a flat out violation of our second amendment rights. /s
On a serious note, I wonder how gold would perform compared to lead when delivering a tungsten core to a target. 🤔
Great presentation Simon!
2:08 “asteroids were able to lug back” lol 😂
Flew over from Ireland for the launch. Memorable experience.
Awesome.
Oh those acronyms!
who else watch this post 25th September 2023, right after the sample of Bennu safely arrived at UTAH?
Hopefully we’ll have a presence in space (or perhaps even the Moon), to make it easier to deal with Way Too Near Earth Objects by the time Bennu swings by.
Having a presence in space with the ability to do anything to a Near Earth Object would unfortunately require every major company to have a hand in it, and that sadly will more than likely never happen.
Each country would be too afraid to let any single country build weapons capable space stations for fear of a "Rods from God" type situation, where the first country to succeed would be the brand new global superpower
@@captainspaulding5963 Anything is possible in 100+ years. If we don’t bother going out into space simply because some are afraid of what a neighbor might or might not do, then what’s the point of it all.
@Padawanmage71 never said we weren't going into space, but there are already things in place to keep countries from building weaponry in space.
There would need to be DRASTIC changes to the way we as a people think about things before any country could attempt anything of that scale. Which is why it would need to be a worldwide project.
I'm not saying it WON'T happen. But with the way humans are at this particular moment, it is HIGHLY unlikely
NASA has been working on a planetary defense called DART. Not really a 24/7 military patrol, but knowing that they have made such a program makes me so happy.
I signed up to have my name on that ship! Yaaay!
Awesome
Thank you. I am aren't I.
Scott Manley made a video called What Would Happen If Asteroid Bennu Hit Earth. Even "just rubble" would be a problem...
"Osiris, what has happened to your nose?"
"I've just returned from Rome."
The accrual of the expenses over that many years, makes this a very cheap project, and it's a science grinding machine, that was expensive to do one thing but almost a decade later it will casually do more science essentially for free
Fortunately Bennu is a loose conglomerate and not a solid rock. So as it nears earth gravity it will break apart and rain down much smaller objects that won't do any real damage. No ELE from Bennu.
I love your dry humor.
Fascinating video! 😊
What time is a good goal to set for myself when running 745.76 shaqs?
Astroid destroying technology.... I'm getting Ace Combat vibes.
Yep I also got Stonehenge vibes whenever I hear about destroying stuff.
1 in 2700 sounds pretty bad to me!!
In the end, it all boils down to poking it with a stick.
Dumb question, if Bennu is SO loosely held together, even if it does impact Earth, wouldn't it just be shredded by Earth's gravity and then the fragments merely burn up in the atmosphere?
I absolutely agree. I think the DOJ has gone too easy on most of these people. Some of these people that got a month to months in jail should have been sentenced to years in jail.
👏Simon! Hey- I remember ( when Dinosaurs roamed the Earth) a few decades ago- Magazines like POPULAR SCIENCE & POPULAR SCIENCE, etc.. - Showcased BACK THEN of; UN-Manned, Computer & Automated MACHINES to go INTO Space: Mine/ Fabricate/ Build Simple Platforms for Space people to Vacation on! That, and 1969 “ Self Driving Cars “!! 👴🏼NoBody.
looks a bit like a cicada.
Ya know... we've got this huge space station still in orbit that it would be a lot easier to transfer samples to rather than risking the sample on reentry.
Difficulty is slowing the vessel down and matching it to the station - doing so would take a lot of fuel and capability.
Much easier to let the atmosphere slow the probe down instead : )
@@Demour77 Easier, sure, but riskier as well. Would like to avoid lithobreaking if at all possible. Orbital rendezvous from deep space is not even Hard Mode for NASA. Orbital Rendezvous is really quite old hat for them, ya know? I bet, if they wanted to show off, they could park the probe 50m from the ISS, on the first try, no dress rehearsal, then treat it like an RC car to dock with the station. Probably wouldn't even need to keep a steely eyed missile man on standby either.
as an American i apperiate the Shaq measuremnt thanks for the clarification
since its not solid the blast calculations are a bit off
"Lonely planetary scientists..." Ouch! 🪐👨🔬
It looks like a tin foil box with a jiffy-pop popcorn attachment.
Saving us from a planet killer; That's more sexy than just about anything.
Apophis, approx 138 shaqs in size
I think you missed an opportunity to compare Bennus gravity to Shaqs... :D
Using Shaq as a measurement system is hilarious. Forget about freedom units. Lol.
ok even if they have a robot land on a astroid and get silver ore or gold. how much do they think they can bring back to earth and make money off of sales from this investment from this mission. a few tons perhaps? at least
Did we knock bennu off course and increase our chances of collision?
Yes
So..... It's a big scary.... dust bunny.
It's a good thing scientist got a tractor beam to work recently
My question about bringing back test samples of anything from space in general has always been, how do we keep these things from contamination?
I know the storage containers are going to be as sterile as humanly possible, but won't the act of collecting these samples and putting them in ANYTHING created on earth automatically contaminate them?
Once these samples come into contact with any man made surface, no matter how clean/sterile we think they are, they are still man made, and just collecting them could irreparably change them.
Interesting stuff, but I didn't hear how far away is it when the capsule got samples
Right?
Love me those Shack measurements >_>
I hear you saying 1 in 2700 but that animation is saying earth is f*cked.
Shaq is how everything should now be measured.
Even temperature?
I suppose that somehow _would_ make more sense than Fahrenheit...
Wtf? Does Simon have a sense of humor or did someone write in that line about the Shaq system?
What if the information gathered from this proves creationism instead of the "billions of years" theory. Would you agree with the data then Simon? Lol
Lol Benu is nothing, we have Apophis in 10-20
Woah you're looking OLD in that thumbnail.
Bennu will not hit Earth, move on.
No it won't because even if it does come close, as soft and easy as it would be to scatter, a single nuke aimed just right would make it into a dust cloud and we'd have a light show in the sky for a few years, with a few "whoomps" of the larger bits that survive entry. I wouldn't want to be on the ISS if that happens... Swiss cheese doesn't make good hull plating...
an 800 million dollar waste
Good to know nasa is working on this.... pitty they always take about 5 times as long as they plan for their projects....
It's a pity they get less than 1% the funding that our military does. Imagine what they could do with 800B per year.
What exactly are you talking about? The probe is quite literally speeding through space on it's way BACK here right now..... seems pretty "on schedule" to me.
Ending a sentence almost inaudibly makes it difficult to understand the presenter.
julian sands or dust on the keyword sheets? how bout buzz? girl scouts? the line was crossed in 2013. they told you it was safe to do so? it's not safe. you're being sacrificed like a russian spacw dog, simon.
What... the actual _fuck_ are you trying to say?
Our American tax money at. The world you're welcome. Again. William s
I'm fine with our taxes funding space exploration. Don't confuse that with me agreeing with taxes, please. What I'm not ok with is our taxes being used to fund wars we're not involved with, and aiding countries who hate us, and call us things like "the great Satan."
Utah is good for something?
The discovery that asteroids (at least some, if not most) are largely clumps of gravel makes OSIRIS one of the most exciting missions of my lifetime.
mm
Not really...Its all fake...Research flat earth👍
"Bennu" is the name for the ancient Egyptian version of the Phoenix myth.
Makes me think of the firestorm it could create on Earth, and the rebirth of life following after.
COVID did what it could. It only stood a chance because of misinformation and freedumb. Just think of all the yummy stuff waiting in the melting permafrost.
The name seems very apt for the asteroid, then.
@@MrMuz99 I have to believe they knew the meaning when they name it .. which is a little concerning.
I must now stop aging so that I might worship this and bring its glorious fires down upon humanity. We must be reborn...
@X - Force - Not really, man. The myth was already told, science has used the term.
Does the nature of the asteroid being a pile of rocks beraly held together make it less dangerous upon entry on earth's atmosphere? Would all these rocks just explode if they get into our atmosphere?
It depends on many factors. Could be a nothing burger, could rain hell down, and everything in between. Best to not find out imo.
Even if it breaks apart, it is the same mass hitting the planet in roughly the same place. It might not make it to the surface, but it could still create enough heat to really mess up the area below it, and if it breaks apart, could spread dust and rock through the atmosphere like a volcano does.
If it hits earth it’ll explode in the air and produce a shockwave large enough to destroy a major city
It will most likely explode over a sparsely populated area and cause a small humanitarian crisis and might effect the atmosphere for a few years
@@QBCPerdition I think the biggest difference would be in how long it would take for the entire mass to reach the planet, or if the entire mass would. Based on the graphics presented the first pass by earth is at a very shallow angle, and it would take many passes to pull a solid asteroid into the planet. These multiple passes would allow Earth's gravity to bleed pieces off of the asteroid over time and allow them to spread out as each is affected at a slightly different rate. I would guess that some would bounce off the atmosphere and many would burn up before impact. The heat would likely be spread across much of the planet and could take a very long time for all the mass to eventually reach us. More importantly the mass that does hit the earth would be spread out over area and time, preventing massive/catastrophic damage.
Scott Manley made a video on that called What Would Happen If Asteroid Bennu Hit Earth. Even "just rubble" would be a problem....
Because there is a lot of it, and it's VERY fast and there is only so much athmosphere in the way.
My parents live on the eastern edge of the Utah test range and I’m still trying to find out if I’d be able to see this when it comes back to earth!
That would be a pretty damn interesting thing to watch, but I'd be genuinely shocked if NASA reveals the landing spot before it happens.... so just keep the date circled and hope!
The landing will be visible. He explains that here: 15:04
1:30 - Chapter 1 - Look to the skies
4:50 - Chapter 2 - Fantastic voyager
8:55 - Chapter 3 - Rock in space

Couple of great albums there eh?
Space is fake...Research flat earth👍 #DefundNASA
You should check out Hayabusa2, Japan's mission to Ryugu and the European Space Agency’s Rosetta mission.
I like the unit of measurement Shaq. It's about as meaningful as imperial units like feet :)
I'm just curious as to what the conversion is between the Shaq and the Blue Whale Unit. I'm pretty sure that would be an important conversion to know!
I mean depending on how far you want to stretch the meaning of the word "life" those little organic chemicals that may have been deposited could be considered ancient aliens lmfao
Is there a NASA think tank somewhere, the sole purpose of which is to make up catchy names for these things?
Not NASA. Dang I can't think of it's name right now but it's a international think tank.
IAU??
I don’t know, but I am pretty sure that they have a PR department tasked with justifying immense budget requests to protect against events that happen on an extinction scale once in 63 million years,
@@jackgibsxxx0750
The IAU is responsible for naming things in space.
They don't so space missions.
@@lordgarion514 .... I was thinking he was referring to the astroid.
@@jackgibsxxx0750
Bennu isn't exactly a catchy name.
AND basically all of NASA's missions have cool names based on what it's doing, and/or it's instruments.
You should look up a list of NASA space probes and landers.
Osiris-REX is maybe average. NASA has a lot more names that are even cooler.
I wonder if Simon can pick up on the "size of Connecticut" analogies.
Might have to take a trip to Utah in September, if not, I'll at least look up and wave as OSIRIS continues it's long journey
You should do a video on MPD thruster engines, over double the exhaust velocity of an ion drive but capable of proper thrust like unlike other electric propulsion. The ISP for them must just be crazy like Vasimir levels. Or one on the nuclear salt water rocket, capable of interstellar level ISP with thrust far beyond any chemical engine. I mean a constant nuclear explosion inside a rocket engine? YES! lets do that!
Dude! this gives me an idea for a heist movie! Picture this. A group of enthusiastic profiteers plots to snag the sample container before NASA gets it and hold it ransom. There's a guy on the inside who causes a computer error at just the right time to send the package hundreds of miles off course. Then it becomes a race across the desert between out fun loving criminals and NASA to reach the probe first. Actually, this would fit right into the Fast and the Furious franchise. Oh and you need a reason you can't use helicopters soooo... Sand storm maybe? Whatever, make a good popcorn movie.
Serious question, I think this will really help me understand things better...Does anyone know what the conversion is between the unit of mass known as the Shaq and the unit of mass known as a Blue Whale Unit (or BWU for short, i.e. the mass of an average blue whale)? I'm kinda stumped by the use of Shaq rather than BWUs, so any help would be much appreciated!
Edit: for clarification, I'm not referring to the similarly named Blue Whale Unit used in whaling regulations. That unit is utterly unintelligible to me. I'm referring specifically to the Blue Whale Unit described as the average mass of a blue whale, I believe it converts to about 220,000 pounds (assuming 1g gravity, of course).
In order to convert a BWU to a Shaq you multiply the sum by 679.01
Now if we're talking about the Shaq unit of distance, the conversion is 7.08 feet to one Shaq.
Edit: In order to convert a sum of Shaqs into BWUs you would devide the Shaqs by 679.01.
@@glockfanboy4635 thank you, that helps tremendously!
God, I forgot about Apophis. I remember in the early and mid 2000's, they treated that thing like Satan. Granted, it was rightfully so. It's currently the only object to have ever been given a rating of level 4 on the Torino scale.
I wonder if you could use the clockwork radio principle to power a probe that won’t be needed to be activated for decades, or possibly even longer.
Like a probe sent to Alpha Centauri perhaps, with Solar Radiometers on the probe to both activate the probe as it nears the Solar system its aimed towards, and recharge the clockwork mechanism like a giant self rewinding watch that never stops running.
The electronics would have to be powered like a clockwork radio, negating the need for batteries or Nuclear power, which will degrade over extremely long periods. This is the issue with the voyager probes as they age, despite the fact that the electronics and computers within the probe are functioning perfectly after nearly half a century of constant use.
The probe would have to be large and capable of making independent decisions, which may require a large amount of older hardier computer chips.
You could even go a step further, and have small landers on the larger probe that could be fired and directed towards other planets. They could be hardy probes, with a self contained non rechargeable clockwork power source of their own. Preferably a hardy probe to gather planetary data quickly, similar to the Venetian and Titan probes of the past.
The only issue would be having a secondary rechargeable clockwork mechanism to power the transmitter, which would have to be very powerful for the extremely long distances to earth. Storage of information until broadcast would be vital.
If Spacex can reduce the cost of launches further, perhaps we could have a mother ship probe that could launch smaller satellites like a Clockwork Cassinis, to examine planetary systems and their moons, as well as launch the aforementioned smaller probes
This is a bit long winded and hypothetical but its worth thinking about…
I'm starting to think these scientists go through a course in acronyms.
Never thought about that, but you're right, they almost have to
Yep. Lol , IKR. Rotf. G1
I'm actually getting sick of NASA's fascination with tortured acronyms. Just name the craft after a person or mythological being that maybe has some connection to the mission or to science in general. Most ESA missions are named after famous astronomers or scientists, and that's just fine. No one remembers what the acronym stands for anyway, so why even worry about it?
Same course the military is forced to attend.
@@QBCPerdition IKR ! LOL ! Saj. Woke sap.
Excellent presentation. Thank you for your great work.
Doomed
Yes. We are.
If it only comes close in 2170 or later, it is IMO quite likely that it will be snagged and dragged off to a smelter or refinery well before it becomes a hazard to planets and astrogation.
Can you imagine if the gravitational influence of a probe impact/orbit/landing accidentally encouraged Bennu into a collision course?
Sounds like a good movie.
Best Project So Far
I wonder if they ever thought of designing the probe and mission so the sample cannister could be replaced and the probe refuelled by any of the two (?) space stations we humans have in orbit.
Why does this sound like the beginning of Andromeda Strain????
Hey Simon
He won't respond. He never does.
“Osiris”-Rex. Naming adoptions like this is is inevitably going to lead to some creative literature from Zechariah Sitchins the LXXVIII… in about 5000 years. Though it is a good name, and the meaning/homage behind it is touching.
