Considering the string would fling humans, which are basically animals, and asteroids are basically rocks, you could exploit that technicality and say: 7000BC: Rock and a string, the ultimate ranged weapon for hunting animals. 2019: Animals and a string: the ultimate ranged weapon for hunting rocks.
Even when a Kurzgesagt video ends with, "but it's impossible for now/we probably just haven't hit our extinction filter/heat death of the universe" type stuff I usually still walk away feeling relatively optimistic because there's always a chance... But then you throw sci-fi dreams of a Star Trek future at us and there's no real "but?!" I'm ready to take on the world today!
It's true, money and the accidental eternal vacuum of space are both 'buts.' BUT, both can immediately be overcome. Discovering/creating new elements or stopping some unknown extinction event are heavy buts. Heavy butts.
The year 2372: Phobos has lost enough momentum from tether transport that it's hurtling down to the Martian colonies. The unsustainable energy supplies of our ancestors threaten our lives. Can James Bond and the rest of the Avengers defeat it? Find out, in Fast & Furious #137!
2820 Phobos velocity crisis solved by re-directing and catching near passing asteroids to Mars surface. Metal prices plummet and the interstellar sling project gets a green light from the United Planets of Finland. First colony ship en route to deep space by 2850.

Not to mention this will affect small orbital bodies such as asteroids/meteors etc., carefully plotted out courses will be altered and will assuredly result in earth strikes that will need to be prevented.

I hope im not alive to see an idiot investing on this idea. Do you have sny idea how many rps this tether would have to be spinning while sustaining orbital speed in order to become a viable choice of propulsion? Lol
@@joweydelanota5558 so what are you gonna do make a bunch of expensive reuseable nuclear fueled rocket like elon musk plan? If you want to do that you must use an energy source that is unlimited. Lets say we will need the dysons sphere first before we can do that
@@joweydelanota5558 I mean, do you? Have you done the math? Anyone with basic physics knowledge knows that it is clearly not about the RPS but about the length of the 'arm'. If the hook is long enough, even a really low RPS is enough for meaningful propulsion. Torque is a relation between the length of the arm, the force applied and the sin between the force direction and the radius direction. We are talking about a ~1000km cable with an asymmetrical weight. Also, since we are talking about space, the final velocity achieved by the hook is kept by the vehicle. Since the vehicle mass is way lower than the hook's mass, the energy transferred to the ship is significant.
There's always a drawback! If everything was so peachy about a skyhook like he says, then NASA would already have plans or already implementing it. It's probably high cost, a logistical nightmare, or other reasons.
@@satanas1729 It is not as new as you may think. The idea goes all the way back to the 70's. You are correct on the need for technological development. After a study in 2001, NASA said that there are no "fundamental technical show-stoppers" but we are still a long way off from even testing it.
The amazing thing about stuff in a stable orbit is that they remain stable even if you mess with their velocities. It changes the shape of the orbit and the distance between them, but if the change in velocity is slow enough it will remain stable. The reason the International Space Station can't just rely on this is that it's too close to earth's thick atmosphere, but that not really a problem 6000km above Mars.
I mean... phobos is so much heavier then ANY cargo we would send up in space... Even if velocity slowed down. It would be like 0.000000000000000000000000001% per trip or even less. Making it pretty much impossible for phobos to slow down enough for it to be unusable as tether for the next 10 Millenia at the very least
There is one component here (That I can see) that would make this incredibly more difficult than it appears to be. In their video, Kurzgesagt noted that the tether would (at its lowest point) be at 80-100km going mach 12. For context, the fastest air breathing jet ever built is widely considered to be the SR71 Blackbird, which could climb to an altitude of roughly 85,000 feet (26km) and sustain a speed of mach 3.14. Constructing an aircraft that can fly at about 4 times faster and higher than this while carrying a substantial amount of passengers/cargo would be insanely difficult. I know Kurzgesagt addressed this in their video too when they said; ""We will need specialized spacecraft to get to the tether, while this isn't exactly easy [its better than rockets]." I just felt like this specific challenge could be covered a bit more in depth. I still agree with Kurzgesagt that this concept is way better than rockets however, also this was just my 2 cents. I am no aeronautical engineer and if I got anything wrong here then I am open to constructive criticism because I am like everyone else here in that I think it would be cool to learn something new today.
To be fair, the aircraft doesn't have to be going that fast. It just has to rendezvous with something going that fast. Coordinating and surviving that much acceleration would be hard, but easier than flying to that speed.
@@lukesenseney1045 Yeah, what seems like an important point to me is the amount of G-force that would be experienced by ship travelers as they use this method. Seems like it would be very intense.
We could also use a giant cannon to launch payloads to the tether sure we would not be able to send living people but it would still allow for probes and building materials aswell as fuel tanks

@@theonejackal89 what. the only place we catapult airplanes is on aircraft carriers. because the deck is to short to get the speed needed for takeoff with engines alone....
The tether will end up wrapping it self up like a yoyo. Then your fucked. You ever played with a yo yo and fuck it up? Yes THAT is how its going to be.
The part where this idea was not obliterated down to the ground was surprising, and if that's the case, this is the next big thing related to space I'm really looking forward to.
@@danielsanjuan7762 mountains at most are only about 8 km tall, the bottom of the hook will be 10-20x higher, there is no danger of it hitting mountains. The only danger is if we use up too much momentum, and the hook falls into the atmosphere
If you like this stuff check out Isaac Arthur (it's a youtube channel called exactly that) it talks about megastructures and engineering projects aliens and humanity might do both in the near and far futures. His most popular and one of my favorite series he does is Civilizations at the End of Time, talking about how civilziations might survive the entropic ends of the universe for basically as long as possible without needing to violate the known laws of physics.
This is seriously my favorite megastructure of all time OMG!!! I remember making a huge plushie of one last summer and watching this video with her and saying “that’s you”. And I’d spin her in circles until she hit the wall and my mum told me to stop “hitting the skyhook on the walls” and I was like “ok” and I still did it anyway lol! I’m literally addicted to this specific video on a hilariously unhealthy level and every now and then, at family gatherings, I’ll just tell my relatives random skyhook facts and they’ll look at me like 😐 and then I pull out *the skyhook plush* I love your videos and I *friggin’ love Skyhooks!!* ❤️🌎🐦⬛
make backroom deal between each other cram as many as you can into the ship without comfort in mind just horrible enough that they still come back. have the same price tag since there is no choice. common and standard tactic and money is more important than the traveler. so i don't think they are coming back.
As someone that's a professional parcel yeeter (sorry, _Postal Support Employee,_ I'm a back-office clerk), I can get behind this. "Oh shit, I just yeeted the spaceship into Route 12's hamper instead of Route 15..."
I'd imagine they could fling the ship into orbit, so that it can try catching it again in the event of a mishap, that or the ship has enough fuel on board to make adjustments to its trajectory
2050 math teacher: If the teather crosses the north pole at 5am at 500kmh and the spaceship takes of from Iceland at 4am at 250kmh . Calculate the speed and angle that should be taken for the ship to land safelly at the moon station by noon. Justify your answer.
Hmm...if we harvest the Ploxanium we could get 500k per kilogram, but if we harvest Slovenarium we could get 100k per 1/2 of a kilogram and its easy to find, while Ploxanium is harder...which one should we harvest?
this is one of the vary rare kurzgesagt videos that not only gives me knowledge but also hope, the others are great but they're usually about subjects I'll never see or have anything to do with so this is great (hopefully, i swear if i never see this in my next 60-70 years of life i will throw an old man fit)
Problem: It's expensive and inefficient to use rockets to send stuff to space. Scientist (possibly high): "What if we, like, threw the rockets real hard?"
BUT, Boeing's Hypersonic Airplane Space Tether Orbital Launch (HASTOL) study concluded that substantial improvement in technology would be needed. In particular, there was concern that the best available material for the tether, Spectra 2000 (a kind of ultra-high-molecular-weight polyethylene), would be rapidly eroded by atomic oxygen.
I can't imagine all the brain-melting calculations and problem solving you would need to be able to catch rockets with one spinning tether orbiting a moving planet or moon to another spinning tether orbiting another moving planet or moon 💀
In the end, it's just about the calculation, it needs to be very precise and very reliable. I'd say we've got technology for it, just another C program running with enough computation power. What I'd worry about tho is the dread when on one day, you get production bug, meaning there is a rocket which missed it's sling and is now on its way to exit solar system. That's gonna cause some headaches..
Honestly, I don't think it's all that complicated. You know how much momentum the skyhook transfers when it yeets a payload, because you designed it. You know the mass of the payload, because you approved it. Using those, you can calculate the velocity that the skyhook will accelerate a given payload to. At this point, it becomes the same as flying a conventional rocket to another celestial body. You can precisely calculate arrival time because the orbits of those celestial bodies don't change. Yes, you're aiming for a moving target from a moving platform, but you know precisely where both you and the target are going to be at any given moment. Once the payload is at it's destination, you just do the same thing in reverse. You know how much momentum you need to arrest, you know the capabilities of your skyhook. It's basically just a matter of not accidentally over or underspinning the skyhook, which is basically down to good planning and emergency engines.
I went my entire impressionable childhood without the slightest interest in space. Your space tech videos are what first got me interested in space. Now I can’t get enough.
Best reason to have high atmospheric refueling is getting a station on the moon. We need an industrial infrastructure to build orbital platforms. I wish we invested in a rail lift platform. The US has a perfect launching region that most of the world lacks. The desert of the southwest US is ideal for it.
You know those highly complex military jets that line up with another plan to refeul mid air? We need those but way more precise and at much higher speeds and altitudes.
Plan for space travel: 1: get to the moon. 2: build skyhook 3: use the moon to get to mars 4: build skyhook on mars 5: use sky hook on mars to get to mercury and Venus 6: make skyhooks on mercury and Venus 7: gather lots of Venus solar energy 8: use solar energy to build railgun on mercury and robots 9: make Dyson sphere on sun 10: profit
Our plan for space travel is getting to the moon then build skyhook on there then use the hook to get to mars then make a skyhook then use it to get to mercury and venus then make solar panels to make railgun and make a dyson swarm to get energy.
What is the most efficient way to get to Mars? SpaceX: Use a luxury rocket with plenty of room and things to do to take the astronauts all the way there in one go. NASA: Use a multi-purpose rocket that has barely any room and just stuff the astronauts in there for 6 months with no regard about whether they have claustrophobia or not. Kurzgesagt Space Agency: rocket go *YEET*
let’s compromise, we put a skyhook on they the same counterweight as a space elevator, you ride the elevator up to where the space hook flys by and get launched without an engines involved.
Martin XY Son: mom where is dad going Mom: he’s going up to the giant trebuchet in the sky Son: he’s gonna die!? Mom: no he’s going to visit mars for work related purposes

The reason the International Space Station can't just rely on this is that it's too close to earth's thick atmosphere, but that not really a problem 6000km above Mars.
I mean... phobos is so much heavier then ANY cargo we would send up in space...
Even if velocity slowed down. It would be like 0.000000000000000000000000001% per trip or even less. Making it pretty much impossible for phobos to slow down enough for it to be unusable as tether for the next 10 Millenia at the very least
It will give colonists a lot of ahem headaches...
LOL!!!! - since if it's not the entire system goes FUBAR and there's no way of compensating since it's already deployed.
@@Kredige Are you saying that if we slow down phobos, it just adjusts its orbit to 6000.0000001 km?
There is one component here (That I can see) that would make this incredibly more difficult than it appears to be.
In their video, Kurzgesagt noted that the tether would (at its lowest point) be at 80-100km going mach 12. For context, the fastest air breathing jet ever built is widely considered to be the SR71 Blackbird, which could climb to an altitude of roughly 85,000 feet (26km) and sustain a speed of mach 3.14. Constructing an aircraft that can fly at about 4 times faster and higher than this while carrying a substantial amount of passengers/cargo would be insanely difficult.
I know Kurzgesagt addressed this in their video too when they said; ""We will need specialized spacecraft to get to the tether, while this isn't exactly easy [its better than rockets]." I just felt like this specific challenge could be covered a bit more in depth.
I still agree with Kurzgesagt that this concept is way better than rockets however, also this was just my 2 cents. I am no aeronautical engineer and if I got anything wrong here then I am open to constructive criticism because I am like everyone else here in that I think it would be cool to learn something new today.
To be fair, the aircraft doesn't have to be going that fast. It just has to rendezvous with something going that fast. Coordinating and surviving that much acceleration would be hard, but easier than flying to that speed.
@@lukesenseney1045 Yeah, what seems like an important point to me is the amount of G-force that would be experienced by ship travelers as they use this method. Seems like it would be very intense.
We could also use a giant cannon to launch payloads to the tether sure we would not be able to send living people but it would still allow for probes and building materials aswell as fuel tanks
we could also make a bigger tether if we have stong materials
I think we would need small rockets to reach it in the first place.

@@Triobian true, but sadly the government probably wouldnt pour billions to make this idea into a reality anytime soon...

The physics & maths involved would be soooooooooooo high level and we have to fool proof it
In the end, it's just about the calculation, it needs to be very precise and very reliable. I'd say we've got technology for it, just another C program running with enough computation power. What I'd worry about tho is the dread when on one day, you get production bug, meaning there is a rocket which missed it's sling and is now on its way to exit solar system. That's gonna cause some headaches..
Honestly, I don't think it's all that complicated. You know how much momentum the skyhook transfers when it yeets a payload, because you designed it. You know the mass of the payload, because you approved it. Using those, you can calculate the velocity that the skyhook will accelerate a given payload to.
At this point, it becomes the same as flying a conventional rocket to another celestial body. You can precisely calculate arrival time because the orbits of those celestial bodies don't change. Yes, you're aiming for a moving target from a moving platform, but you know precisely where both you and the target are going to be at any given moment.
Once the payload is at it's destination, you just do the same thing in reverse. You know how much momentum you need to arrest, you know the capabilities of your skyhook. It's basically just a matter of not accidentally over or underspinning the skyhook, which is basically down to good planning and emergency engines.
FYI: T-Mobile customers won’t have internet on the Skyhook, because tethering is not included with their contract.

Until you realize that is just how space works. Rocks being flung all over the place, some of them being caught in stable orbits around big balls of hot gas or other rocks circling said gas orbs. We would just be doing what nature is doing.
