Can we Mine Large Asteroids? Neil deGrasse Tyson on The Risks & Benefits of Giant Asteroids

- Considering the fact that giant asteroids collide with our planet every 50 to 60 million years, and the fact that the last major asteroid impact was 66 million years ago, the Earth is overdue for another cataclysmic event.
American astrophysicist, planetary scientist, author, and science communicator, Neil deGrasse Tyson explains risks and benefits of large asteroids.
When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry.
But even our atmospheric protective shield is no match against the size of killer asteroids. Neil deGrasse Tyson mentions the fact that dinosaurs went extinct from a a 10km-wide asteroid that hit the area which is now the Gulf of Mexico.
A widely accepted theory is that worldwide climate disruption from the event was the cause of the Cretaceous-Paleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs.
Neil deGrasse Tyson also mentions the feasibility of mining asteroids. Asteroids could one day be a vast new source of scarce material if the financial and technological obstacles can be overcome. Asteroids are lumps of metals, rock and dust, sometimes laced with ices and tar, which are the cosmic "leftovers" from the solar system's formation about 4.5 billion years ago.
However, it currently costs hundreds of millions to billions of dollars to build and launch a space mission, so innovations that would make these costs fall dramatically are needed before it is profitable to mine asteroids for the value of their metals alone.

It was very powerful when Neil said that he doesn't want Humanity to be a laughing stock for other intelligent alien species if we were to go extinct to an asteroid while having space technology.. Humanity really needs to unite and think big, because Earth is nothing compared to what's out there.
Ya the dollar does not matter if there is no life on the planet.
"We'd be the laughing stock of aliens if we died from a preventable asteroid."
Well, yes Neil, but more importantly we'd be dead. lol
❤❤ but it’s true! We are laughing stock to the galaxy!
We're all going to be dead eventually but to be laughing stocks AND dead? I can't live with that!
I think that statement was tongue in check.
I think space mining could be very beneficial for humanity and conserve our planet resources. Hopefully, we could find the technology that could enable us achieve this in the future.
So Decrease The Cost To Go Out To Mine To Become Richer Than Ever Needs To Happen For Who Ever Can Get This Done Congratulations 💯💯💯
Isnt there something worth mining from the Chicxulub crater?
He is right, I don´t want to be laughed by other ets which they have all the right to laugh if humans don´t like to go to space, well at least I am doing my part, there is too much TOO MUCH average boring humans.
Could set up base on moon for deflecting asteroids and comets; maybe even use moon gravity to block space rocks
How would we use the moon's gravity anymore than we already do by doing nothing and just letting the gravity attract any asteroids that come close by it?.. we would have to actually move the Moon or the asteroids to do anything in order for them to make contact to keep the asteroids away from Earth and at that point why not that just nudge them out of the way of both the Earth and the Moon so we could set up a colony on the moon that doesn't get periodically destroyed. I don't think you really thought that one through lol
I don’t why we can’t do both This is more defending our home! We can use the resources of asteroids instead of earth! For fuel and space ships part
I like it this document 📄📃
I love his brain.😍😍🧠🧠
We live in a “Innovation Nation”.😃😃
Can they detect asteroid or comet that is heading for collision with earth far enough distance away to nuke without fragments hitting earth?
The idea is to fragment it enough for the atmosphere to do its thing.
Could there be an asteroid not from or within our solar system filled with material not on the periodic table? Would that matter or material be worth more?
Avatar Unobtanium 😊
yes billions.
Is it possible to change the composition of the asteroid, make it lighter or heavy?.
The one that killed the dinosaur was 10km. 10km isn't much to change or break down considering the advances we have made in weaponry
Lasers pulsing might be used to nudge it.
Wouldn’t moon mission cost 10x more in 2020 ? If that’s the case wouldn’t space mining far outweighs the profit in next decades ?
And how can you innovate space mining if there is non ? How would you ini ate MarkII into a better computer if there weren’t MarkI to begin with ? ? Wouldn’t it make sense to have space mining at any cost so that then we can innovate it ???
Yes and no! We need start testing the technology somewhere! The moon is perfect because it’s only 3 or 4 day trip
Yes The fun part will be getting it back to the surface of earth. But we have ideas
I wonder if anybody that has an underground shelter would survive the asteroid?
WHY Mine Asteroids, when you can Import any material into the Earth's Program, through Accessing
"The Processing System of LIFE"?
Apparently mining can't be a problem to humanity.
As we are becaming interplanetary beings.Yes🌺🌺🌺💻
you just assumed the second planet will be mineral rich as earth
When I hear people tell me space is an irresponsible waste of tax dollars, I just remind them that the reason they're talking to me from across the planet, is precisely because we humans went to space.
I'm second.Wheres my award
What if we had satellites set up in orbital relays, all the way thru the solar system. Allowing us surveillance through our solar system and perhaps surpass that. And the less delay would obviously be best....
So your telling me a 200 Megaton hydrogen bomb wouldn't move it not even a little?
NASA launches Dart mission to crash into a near-Earth asteroid to try to change its motion in space
"However, it currently costs hundreds of millions to billions of dollars to build and launch a space mission" - The promise of inexpensive lift offered by SpaceX might quickly change these views that currently dominate the industry. A new peer-reviewed article about the use of shaped charges in asteroid mining did just that. JOURNAL-OF-SUSTAINABLE-MINING “REVIEW ON QUARRYING METHODS SUITABLE FOR SPACE MINING MISSIONS”
We need an International Mining Station (IMS). Anyways if we solved problems on Earth 1st we'd learn real things & not waste time & resources of things that may fail.
❤ I’m 100 behind Neil! The reality is space is our saver and future whether we like it or not! If we don’t want to go the same way as dinosaurs! Then we need start space and exploration ! Seriously
The saying was supposed to be hope in one hand and you better do something with the other that’s what they saying was supposed to be
If we prey enough and bow before God, no asteroid will fall upon us. Just kiddin..
well when a new planet is formed the two planets hit against each other ( like big bang theory) sending pieces every where.
Yeeeuhhhh
At night our world is lightened, how come we dont see in other worlds? I know it’s stealth, ohhhh ok .We are The strongest of them, i think, we are first, 😎, look at us , we are
Boom baby first
Congrats man on your great achievement 😉
We're not worthy!
🙏🙌
😅8 billion of us now!
We have been a laughing stock already during Covid, when the lack of proper masks, gowns and eye gear imperilling the ability of medical workers to fight the coronavirus.
upside the new golden age-- download destruction all we love due to corp greed
I want to visit the moon
Video was good, but to adds SUCK
Asteroids could be the original intergalactic naturally occurring space ships, they have everything you need to traverse through the cosmos...so why not aquire what possibly many are already taking advantage of, just don't shoot the messenger.
The problem is how do you slow it down?
Inertia would crush yoy
@@drsatan7554 why would you want to slow it down when you can detach and reattach.
@@Nobody_Here_Except-Us_Ghosts how would that help you disembark?
Not take care of things on earth too well, mining asteroids probably not good idea
Why not? Think about if we exploring an asteroid will help this planet
Dumbarse idea!
People thought that about the airplane! Some people prove self doubt wrong!
@@dumitrulangham1721 always have to calculate the comparative cost of accessing that mineral or element from here on Earth.
