Defending Earth from Asteroids with Neil deGrasse Tyson
Вставка
- Опубліковано 9 лют 2025
- There are about a million near-Earth asteroids that are large enough to substantially damage or destroy a major city, as evidenced by the explosion over Chelyabinsk, Russia, in February 2013 of a meteor no bigger than a large truck, which injured more than 1,000 people.
With current space technology, scientists know how to deflect the majority of hazardous near-Earth objects. But prevention is only possible if nations work together on detection and deflection. Learn about the risks, and the steps that are needed to avoid these potential natural disasters, from a group of astronauts and cosmonauts who recently helped develop recommendations to the United Nations for defending Earth from asteroid impact in this discussion.
This program, which was streamed live on the web, took place at the American Museum of Natural History on October 25, 2013, the same week the United Nations General Assembly adopted measures creating an international decision-making mechanism for planetary asteroid defense. The event was co-hosted by the American Museum of Natural History and the Association of Space Explorers (ASE).
Neil deGrasse Tyson, who is the Frederick P. Rose Director of the Hayden Planetarium, hosted the discussion with participants Thomas Jones, former NASA astronaut, senior research scientist at the Florida Institute for Human and Machine Cognition, and Association of Space Explorers (ASE) Near Earth Objects Committee member; Russell Schweickart, former NASA astronaut, ASE co-founder and Near Earth Objects Committee member, and co-founder and chairman emeritus of the B612 Foundation; Dumitru-Dorin Prunariu, former Romanian astronaut, ASE co-founder and Near Earth Objects Committee member, and vice president of the European International Institute for Risk, Security, and Communication Management; Edward Lu, former NASA astronaut, ASE Near Earth Objects Committee member, and co-founder, chairman, and CEO of the B612 Foundation; and Soichi Noguchi, engineer and JAXA astronaut, and ASE Near Earth Objects Committee member.

Ever since I discovered Neil deGrasse Tyson I'm hooked, such a great scientist and human being!
Except he is accused of several sex offences. So maybe not a great human being. Even wiki reports this.
@@jasonbuckley2227 Sad to break it to you, but not everything you read on the internet is true;
in the case of male celebrities accused of sexual misconduct we see a lot of false accusations, and the reason for it is simple: the possible accusers greatly outnumber male celebrities;
for instance, let's try to stay realistic and assume that in the US there are around 3.000 male celebrities and 150.000.000 women; it's a ratio of 50.000 to 1, wich means that it's very probable that a lot of women at once will focus their attention on a single celebrity;
now what do you think it's more probable? That all accused male celebrities are actually guilty of what they've been accused, or that there are a few out of that enormously more large group of women that made up a false story? The latter, clearly.
Wich is sad really, because this way the real cases of sexual misconduct get lost amongst the sea of false allegations and therefore lose credibility;
finally, in the case of Mr. Tyson, judging by the extremily low crime rate amongst highly educated people, we can think of any accusation against him without evidence to back it up as very much improbable.
To give you a tool of comparison, pretty much everywhere on the Internet you'll find people insulting each other over the most trivial things; that doesn't mean that everyone around you is crazy, it's just that so many people have free access to the Internet that is bound to include a percentage of the population, even if small, composed of uneducated / rude / mentally unstable people
I have never heard of Ed Lu before but he said something really cool.
"100 years ago, that was bad luck, if it happens again in 20 years that's not bad luck, that's stupidity. And I think we, as a race, can do better."
Go.On.Son.
I just thought that was really cool.
The human race has proved it is stupid many times.
faux0pas I
We has a species humens are not a race 😆
@@michaelramirez6211 I think "human race" is a good expression because it means we are one group, not 250 different sub- groups of peoples.. let's not divide anymore.
Forget about the differences.
Ed Lu makes me feel like a guardian angel for owning a telescope.
The view count of this video is not reassuring.
First thing I noticed coming to this vid: Why haven't more people seen this?!
A single one could make a change for the good.
There are 86.842 views right now.
That equals to 86.842 chances for a change for the good.
@@Seldomane I'm watching in 2023 (for the third time), there is only 126,000 views. humans are really mentally like ostriches: they stick their heads up their asses and say nah-nah-nah as impending disaster comes.
It is a shame that we have to wait until something big happens before governments do anything.
The US govt is essentially a teenager. Maxing out the credit card (national debt), and playing havoc with trade economies and international relations (testing their boundaries)... NASA currently gets less than 0.5% of the total national budget... we should seriously tax religious donations, drop all wealthy tax dodges, and really put a % on the federal tax. THEN give more like a 15% chunk of annual budget to NASA.
April 13, 2029. Apophis is coming...?
Not all governments, but most.
I hold Neil Degrasse Tyson in very high regard and have seen countless of his speeches , but somehow in this interview I see him as humbled to talk to these people as much as I would be listening to him. Don't know if its just me.
Everything that was said in this presentation fell on deaf ears.
this is why i love youtube. tyson for an hour.
1chance in 10. One in every 10 years the magnetic field flips.
I really like Neil...
Yeah baby. I am always searching videos with Dr. Neil deGrasse Tyson, so thank you very much for having him as a speaker and placing it in you tube to be watched by fans like me.
It has been clearly stated by mr. Tyson in an interview, ''There's no way to observe all space at all time". Unless we've made a huge leap in technology, were still looking at damage.
Jake Hamilton that statement he said is true, but NASA has mapped an enormous amount of asteroids and will continue to map them as they are discovered. So while we may not be able to watch everything at the same time, we can calculate the trajectories of each of those asteroids and determine which of them poses an actual threat to earth. Most of the debris in space we don’t even need to worry about because it will just vaporize in our atmosphere. We actually fly through something like 200-300 tons of debris every day but it doesn’t even so much as leave a mark. It’s like your car on the highway, you don’t worry about the bugs flying into your car and getting flattened, it’s just an annoyance that you’ll have to wash off later
Personally. I feel safer already. Surprised there was no mention of Chuck Norris, though.
Have you ever heard, Apophis? (April 13, 2029) or (sometime 2036?)
As a biologist, you can think of astrophysics as the origin of your speciality. Biology came from the cosmos, is part of the cosmos and thus it is natural for you to find it fascinating.
Anyone have an update on this?
Well
Now this is more important then ever
Any updates on this subject?
Yes. On 26th September 2022 NASA’s DART mission employed an asteroid-deflection technique known as a “kinetic impactor,” which in simplest terms means smashing a thing into another thing - in this case, a spacecraft into an asteroid. From the data, the DART investigation team, led by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, found that a kinetic impactor mission like DART can be effective in altering the trajectory of an asteroid, a big step toward the goal of preventing future asteroid strikes on Earth. These findings were published in four papers in the journal Nature.
The images shown at around 15:00 of the injuries sustained by the local populations affected by the Chelyabinsk meteor Event in Russia were caused by the effects preceding the atmospheric impact, rather than the meteor itself.
The Chelyabinsk meteor was a superbolide that entered Earth's atmosphere over Russia on February 15th. 2013 at about 09:20 YEKT (03:20 UTC).
It was caused by an approximately 20 m (66 ft) near-Earth asteroid with a speed of 19.16 ± 0.15 kilometres per second (60,000-69,000 km/h or 40,000--42,900 mph).
It was so sudden and brilliant, the light from the meteor was brighter than the Sun.
It was even visible up to 100 km (62 mi) away.
Observed over a wide area of the region and in neighboring Republics, one eyewitnesses claimed to feel intense heat from the fireball.
You've undoubtedly seen plenty of UA-cam videos about it lol there are MANY. 🌠
Because of its high velocity and shallow angle when it entered the atmosphere, it exploded in an, "air burst," over Chelyabinsk Oblast, about 29.½ km up. (18.5 mi; 97,000 ft).
The explosion generated a bright flash, producing a hot cloud of dust and gas that penetrated to 26.2 km (16.3 mi), and many surviving small fragmentary meteorites, as well as a large shock wave.
The bulk of the object's energy was absorbed by the atmosphere, with a total kinetic energy before atmospheric impact estimated from infrasound and seismic measurements to be equivalent to the blast yield of 400-500 kilotons of TNT. (Or; 26 to 33 times as much energy as that released from the atomic bomb detonated at Hiroshima.)
Because the object went undetected before entering the atmosphere, mostly because its radiant was close to the Sun, the explosion created panic among local residents, and about 1,500 people were injured seriously enough to seek medical treatment.
All of the injuries were due to indirect effects rather than the meteor itself, mainly from broken glass from windows that were blown in when the shock wave arrived, minutes after the flash.
Some 7,200 buildings in six cities across the region were damaged by the explosion's shock wave, but people saw a bright flash and naturally went directly to the nearest window to look outside lol and, "investigate."
Clearly, this presents a rare but significant opportunity for the rest of the world to learn what NOT to do in a similar situation lol if you see a flash brighter than the Sun, the LAST thing you want to do is go looking out the window! 😂
Knowledge and understanding , the key ....
Great presentation and discussion by a wonderful panel.
where can I see the Asteroid Threats Report?
I watched armageddon Again 18 years later and come to the conclusion that we can send Bruce Willis to all of them and blow them up?
blomgren182 yes and Ben affect grew up to be Batman so it will be a big help too.i think we have a chance
thank you for posting! I did have things to do tonight but bah w/e Il just watch tyson for an hour.
No one is ever gonna do or pay attention to this up until something will be discovered to come and finish us
This should have a 6 billion views
The problem with that is 5.5 billion are not intelligent enough to understand it..despite giving the false credit towards so..really they are not.
@@metalhead0274 Agreed, most humans beings are far more unintelligent than we would like to admit. And even those that do have the mental capacity to comprehend things, are too damn lazy to make an effort to do so, which is why there are only about 6000 astrophysicists in the world, out of a population of 8.1 billion people. Whereas there are about 20 million lawyers in the world. Pretty much says it all as to where our priorities, or lack-thereof lie.
you got this, sir!
I'm a biologist and my favorite science advocate (by far) is an astrophysicist. It boils down to fire liking water. Am I bringing chaos to the universe?
I initially clicked on the link hoping for a discussion of Apophis and the like. And got really disappointed by a discussion about the creation of committees and sub-committees. It's like trying to find a tutorial on how to win at football, and finding a video on how a football team works.
that was seven years ago... they warned us... thats all we need now in 2020
Bill Gates and others warned us about a pandemic even before that. Sadly, I have little hope for humanity. Carl Sagan and numerous scientists have warned us about climate change beginning in the 80's. Things are following their predictions and yet here we are. 😞
Yeah!! Sometimes it is easy to forget that we, everything on this planet and the planet itself are very much in the cosmos and of the cosmos, we are made of the cosmos.
Right now we're defenseless people
This museum is in NY right? Do they still have the Barosaurus skeleton in the lobby?
Thanks for the upload! Very informative.
new Tyson video.. yeyy!!!
I believe we have the technology to deflect an asteroid but I think it would be very hard to do.
+nuoipter termer Anything worth doing always is.
***** I think when the survival of the entire Human race is on the line it's not gonna be that hard to do.
I'd dare say the opposite. To deflect an asteroid it would take very little effort, a very gentle push could change the trajectory dramatically. The problem is getting the invention up there to push it, which Neil said himself would take 10+ years to develop.
Gravitational forces .. All objects of greater masd has gravitational force.. Use that law of gravity to draw it towards the object..
If it is a ship.. Then you can move itslowly.. Because it can move.. Just use gravitational force to drag it with slow gravitational nudges ..
To be fair we don't actually know that. All we know is that they didn't ask any questions during the Q&A session.
So cool.
They are very aware of a potential hazardous astriod ..
how about the idea of robot satellites out farther in our solar system to be able to detect these things. maybe have them working together to push these comets or asteroids away from earth.
Truly that is an idea that has been purposed. With the coming of the movie "Gravity" many people now understand what it's like when you have an orbit of satellites where one has an accident and they all fall in the debris. However, I completely agree with you. Robots are the future of space for our foreseeable future. Robotic controlled satellite/space drones will be responsible for altering the path of those possible planet killers. Well said!
Hope to see that telescope in space soon.
The UN will send the asteroid a sternly worded memo.
Yes, the Barosaurus is still in the lobby.
Huh... no mention of the asteroid Apophis. I am surprised, it falls under the classification they are speaking of as far as mass goes.
Apophis will miss. Your comment is 7 years ago. We know more now.
While it is a nice goal, I have to wonder if all of this research might result in an asteroid hitting earth sooner rather than later. I mean, since when have we ever developed a technology that we didn't try to turn into a weapon? Once we master the detecting, plotting and nudging these objects, you basically have a very deadly weapon.
This is scary true lol
and now we have the comet research group!
It is bittersweet (personally) for me to have been an excited and optimistic pre-teen who was one of the many millions to have witnessed Apollo live on the TV, but then to see the promise of more manned deep-space flight missions shelved because of shortsighted and petty political bickering.
The sort of idiotic lack of vision for the potential of the Human species that now, coming up on the 45th anniversary of Apollo 11 next year, I wonder whether I will live to see the inevitable first manned Mars expedition.
hey, we'll get there ok! be patient, maybe not in our lifetime but have some hope
There are plans from entrepreneurs to start sending teams to colonize Mars in 2023. The guy was even trying to make a reality tv show out of it. Something like 75,000 people volunteered to do it, but it is in the beginning stages. Things are happening. It's just not the governments that are doing them now.
***** @'Kevin Jorrey':
Yes, I had heard of this already. The future of space exploration might very well rely upon "private" funding, as in "private enterprise" (small nod to 'Star Trek' there, and fully intended).
What I mean is, whenever there is a potential for a profit motive, then "Big Business" will eventually get involved. As to this "2023" effort? Well, unlike the Apollo missions that lasted at most two weeks (14 days), a mission to Mars is much, much longer in duration. There is the matter of provisions...food & water and environmental concerns for a manned crew...and of course, the biggie.,,,:
The radiation. cosmic background radiation, and Solar radiation...and any Solar Coronal Mass Ejection (CME) events that might occur during a mission, and that are "aimed" along the plane of the orbital rotation of the planets....meaning, roughly occurring at or near the Sun's equator.
The matter of radiation is often brought up by "moon hoax nuts" in attempts to claim that Apollo was somehow 'faked". Those people are only partly correct. As mentioned, a 14-day mission outside Earth's magnetic field is easily survivable. Several years, though, presents a big challenge.
@@WeedWhacker2010 Private enterprises will never take the first step for space exploration. Only governments can risk the $$$ on such Endeavours. (My puns were also intended)
Very encouraging. Thanks. Puts things into a more comfortable (not complacent) light. I do wonder about progress in development of global force-fields (for example) to deflect impactors (and gamma ray bursts, wandering black holes, alien attacks, etc)? A pretty tall order, but what's the thinking on protecting the species in the face of such other universal hazards? I suppose space colonization would be a good way to hedge our bets?
Ed hu is incredibly smart.
Thanks to geologists we think that all living beings on our planet Earth have the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters. Certainly, a cycle of regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. The Northern hemisphere is covered with a layer of ice that fell down "in blocks as great as mountains". These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its timeline and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
Hopefully NASA has upgraded this issue since 2014. This is unacceptablely too old
You get how that title reads, right?
Imagine a hall pass written by Neil deGresse Tyson?
"Use the force Luke" :) .
Grow up.
The Astronauts are going to save us.
Neil suggests that each country could donate some amount directly related to their GDP (or other measure of wealth/production), but aren't certain countries more or less likely to be impacted by these asteroids? For a smaller asteroid that is a city-destroyer, wouldn't it make more sense to add a probabilistic component? Certainly, a larger asteroid that could cause an ice age would pose an equally likely risk to each area.
thinking back, I think I can totally see where you're coming from. I also noticed that even within the engineering faculty, each branch makes fun of the other (mechanical, chemical, integrated all look down on others). human nature i suppose :P
Did you notice there was no major MSM rep there? CNN, BBC. I find that level of un-interest pathetic.
Humanity IS pathetic.
I wouldn't discard Dawkins though. He's as passionate as Neil.
YAY, MORE TYSON! :p
We won't always have 15 yrs warning!
AI will identify and track near-Earth asteroid threats. I think the theory of being able to deflect an asteroid's path has been proven on a small asteroid.
2:27 is what you came here for.
damn they are sweating... you can see stopping frames how everyone reacts. this shit is going real i love it. thanks neil for everything thanks everyone
elon musk should be up there since he will probably be the one to save us when the time comes.
Hes going to send you to Mars to die. Hes trying to escape the wrath of God
WHY CAN'T I HEAR THIS?!?!?!
With the fear maintained with nuclear strikes and spills, It may be a
good thing to really enhance the odds on defending our selves.
YVO
Maybe it's something I'm experiencing at my university but there is a lot of disdain between fields of science where I'm from. We mock biomedical sciences for instance and they mock my field of marine biology and evolution. If I tell my professors that one of my role models is an astrophysicist I will get laughed at. But, all in good fun of course!! Just take my statement with a huge grain of salt.
Oh, it's actually romanian accent that everybody in Hollywood thinks is russian accent
but since mars is closer to most of them its better,thier income,vs job flutuations.then there is its metal storage capabillity.i have to say it,its a space mining colony.the glory goes to its redesigning of solar systems.
you tell me
Except the Bible has nothing about asteroids hitting us.
At least until the Tribulation; then the Earth is toast.
Never mind, I found it!
There are 45 Ken Ham-ers who tried to watch this video
Could an asteroid pass by so close to the Earth (without striking), as through the upper atmosphere, that it might pull a significant volume of atmosphere with it into space?
Im not qualified to answer this but I cant help but think of Spaceballs after reading this question. lol
@@daveherron I love Mel Brooks--- Space Balls, Blazing Saddles, my favorite, Robin Hood, and many others were so hilarious.
Hi, uneducated opinion here; I think that it would be impossible because any object that would come that close to Earth would be attracted to Earth's gravity to such an extent that it would inevitabily collide with it; again, I haven't done any calculations, but considering most of Earth's atmosphere is condensed in the first 100km I don't think that an asteroid could come that close and still escapes the collision; also, I don't know exactly how different gravitational pulls overlap, but unless the asteroid is of considerable size I think Earth's gravitation pull would "swallow" the asteroid's one
Edit: corrected some typos
:) You may have just brought back balance to the universe!
the third from our left is an romanian ,and went to space once in 1983,...they all went to space sure ,how many times :1
Beautiful mind. SMART American people. i love it. increase you intelligence. wow. ALL THAT I KNOW IS THE FACT THAT I DID NOT KNOW BUT NOW I KNOW A LITTLE MORE.
not sure how a biologist liking astrophysics is like fire liking water :S isn't science pursuit of truth?
Dear panel of scientist...this video is a little getting older now....it is now the year 2020....can I ask how much development have there been so far as far s deflecting the real threatening asteroid ( that’s asteroid Apophis ) that’s on its direct path in our galaxy towards earth....and where are you now with this international space program with its deflection before it makes its first pass on earth by 13th April 2029.....do we have a big chance of surviving it with its second pass on same date on 2036 even if it’s only deflected a tiny little away from earth at least before 2029.....can you give us a little bit more honest information please..>
Where in my comment do i strictly point out a uniform mindset of every individual on earth? I admire and wish projects like these every success however their actions are like trying to bail out a sinking cruise liner with a thimble whilst a tsunami approaches.
how bout defending earth from the gases of uranus
Fantastic..his theoretical red line passes over my country 😦😦😟😅
Let's catapult Tire Irons for 10 ton trucks at incoming space rocks.
there's just ONE space romanian out there and Neil degrasse tyson gets him wrong :((
Defending Earth from Earth haters with Neil deGrasse Tyson
If Apophis hit America our earth will be peaceful as heaven....
8 People want the Asteroids
to hit out planet.
+whanaublood Nah most of them think NASA is all bs and everything they say is a lie.
I want an asteroid to hit.. but still gave the video a thumbs up.
given tools are closer than a good brain.asteroids can.give vesta to mars,move venus,or mars.interupt any comet.and from a military stance great battle ships.the question is which ones have mineral wealth.
Invent a DISINTEGRATER GUN💯 like Marvin the Martian has!!😁
Time for the woman!!!! 💪🦋🌈✨
I find smart people to be intellectually attractive.
we need to have more than 1 plan on have to deflect an Asteroid, because we don't know how much time we are gonna get to deflect it in, we need to have plan a, plan b, plan c, and so on, because it depends on how much advance warning we are gonna get to deflect it in, a day, a week, or maybe a year, who knows,we need to be ready for it. !!!
P.A. Jacobsen well we know of one called apophis which MIGHT hit earth in 2036, so we have 19 years to figure it out. If it hits us then we deserve to go extinct
to bad the big guys are so hard up building there obsolete rockets and thrusters. My VCMD prototype works.
t-bird shane then why don’t you put your money where your mouth is and show them how to build a rocket? 🤔
the romania fauxpass...dude, thats just something you dont get wrong ;) otherwise very interesting presentation.
heck no! science rulz
Neil @ 2:30.
right now every one is bitching about who is going to pay for this. i fear that it wont get settled until we ALL have to pay for it....p.s. this is about asteroid deflection for the good of the planet for us all, not "defence syst" for the paranoia of one country. besides, we are talking NASA budget not DOD.
Yeah, UFOlogiests :). Didn`t we lost earth already in 2012?
I wonder if there are any asteroid-deniers out there?
Enough of them that nothing will be done when Apophis or another asteroid is heading straight for us.
It’s not going to hit the Pacific! It’s going to hit Ireland!! Europe.
Dear blixx66...I just read your clever comment and wanna THANK YOU for making me LOL for Real !!!
did you have anything to do with earth's creation.. or your own?
That answer is as obvious as whether a god creator did.. We say an absolute NO to both..
