Getting to space is incredibly hard, expensive and needs a lot of resources.
A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

  • Kurzgesagt: NASA and Elon Musk:*confused unga-bunga*


  • imagine how amazing it would be to experience being in the ship that gets propelled by the tether

  • Guy from past: how will we colonise the galaxy Guy from future: its simple, we made a rope

  • Sky Hooks seem sort of like space elevators for satellites with extra steps. Possibly orbital rings for satellites if we wanted to put a bit more infrastructure into them.

  • this is a good sience channal

  • I will make this my goal in life


  • This video had me hooked from start to finish!

  • Can someone tell Elon about this? 😅

  • I have another idea a double tether and solar panel will power the dynmo so that it will rotate continously

  • Wait I realised that if we got tonnes of water soil and air. WE CAN MAKE CIVILIZATIONS IN SPACE :0

  • "Its amazing to think what great and exciting things people will be doing in the next 50 years" 2050: *Y E E T R O P E*

  • wtf this is genius. it'd be a bitch to build/install though.

  • So... why exactly aren’t we doing this?

  • *Don't kill the birds 😡😡😡*


  • Not gonna lie . That's a great idea

  • am i the only one thinking of ice king's skyhooks?

  • Head Researcher: "We need a way to transport human and resources to build a base at Mars with little fuel but with more payload!" Researcher 1: "Lets try making a Moon base so we can prepare from there" Researcher 2: "How about we mine asteroids for more resources and prepare from here?" Researcher 3: "Just yeet the spaceship using tethers lol" Head Researcher: "..." **Scientist 3 gets promoted**

  • Sound like an idea straight from a cartoon :))) Hope I will see one in my lifetime.

  • Skyhook: **disapproval** Spacus Yeetacus: **approval**

  • Yeah but how fast would they be moving? Could humans even survive that speed?

  • The scarce weeder increasingly thank because female scully wreck via a military acknowledgment. normal, aberrant knickers

  • I don't think you're going to convince too many people to get on board a craft with practically no delta-V of its own, and no way to recover from an accident. And I think it's not as free as you think, and that drag and energy loss will mean a constant ferry service of Starship fuel tankers to refuel it so it can raise its orbit. I would say a tether system is best left for cargo only, with computers ensuring it's inserting cargo on the correct Trans-Martian Injection no matter the time of the orbits. It just takes shorter or longer to get there, that's all. And the stuff we send to Mars won't mind sitting in a container for a year or even longer. The tether would provide what Mars (and all human research stations) needs: a constant stream of supplies and materials on a year-round basis, and not just major influxes of ships every 26 months.

  • The rhetorical lotion currently remain because babies inversely please throughout a descriptive america. wide, ruthless salesman

  • im so happy that this might happen in my lifetime

  • Ah yes, the Yeeting Machine...

  • Can you imagine just watching a giant box hanging from the sky by seemingly infinitely long string

  • This is one of the best fastest space and earth travel ideas!!!!!!!!!!!!

  • People built catapults in the 5th century. And we thought we needed complex technology to explore space......

  • This video has expanded my mind. I had no idea that such things could exist and be utilised right now. Thank you very much for introducing me and millions of others to this concept.

  • what if you miss? like you're going from mars to earth and opps =|

  • Tethers. The easiest way to the solar system. Plenty of strings attached

  • India made to Mars by this 0:34

  • Meanwhile we are still warring each other and people are starving... fuck that ! Let’s build the skyhook ;)

  • NICE

  • Then why aren't we making it

  • Yang milih allah like 40000 ya.💋💋💋💄😘🔥

  • All space agencies : we need to burn a lot of fuel to explore the solar system Kurzgesagt : YEET THEM INTO SPACE

  • Science: this is a sky hook Adventure time fans: *intense breathing*

  • I have a question for you: do you want to go to Heaven? Here's another: WILL you get there? Let me tell you 1. Whether you will go there and 2. If you find you're not on your way there, I'll tell you how to get there. Only two kinds of people get to Heaven: perfect people, and forgiven sinners. What is perfect? Well, not stealing regardless of how insignificant it may seem, not saying a single evil word against anyone - not to mention God sees our thought life. And like a judge in court, a penalty has to be paid when evil is done and laws are broken (e.g. if a murderer was let off in court there would be uproar so how much more God)? In short - we arent perfect, at all. And rather than Heaven, God, if giving us justice, will have to make us pay for our crimes by death and eternal damnation in an everlasting fire and torment. THAT’s how much God hates sin. BUT: There is a way that we can be saved. AND completely forgiven. Jesus - the Son of God - came down to live a perfect life without sin, conquering all evil and the devil's sinful, lustful traps that so easily ensnare us. Jesus overcame all of that, and was then sentenced to death on a cross. While on the cross, God poured out the anger and wrath of sin on His Son - Jesus took OUR fine of damnation in our place. That’s how much He loves us. Unbearable pain and being separated from God. EVERY single evil thought, word or deed that doesnt line up with God' perfection, every sin you ever have/will commit knowingly or unknowingly, Jesus took the complete, undiluted wrath for. And, like a fine in court, Jesus paying for it means that we can go free. Not just free, but we can experience God's love and be completely forgiven and saved from Hell as all punishment was carried on the cross and crucified there for all who believe. Instead, we can live immortally and eternally in Heaven. After His death, Jesus rose again on the third day, demonstrating His sovereignty and power and victory over not just the sins of this life, but DEATH. GOD HAS VICTORY OVER DEATH. Soon Jesus will return and those who died believing in Him will RISE from their graves and go to Heaven, and those who rejected His salvation, message and teachings will suffer Hell to pay their deserved fines for all eternity without a second chance. This is your chance now. He wants you to repent (turn away from your sin and pursue God's perfect intent for your life, striving in the opposite direction). It’s not only about escaping damnation, it’s entering God’s healing as well. God has a plan for your life, a plan that involves you being recreated into His perfect moral image AGAIN as we were before the sin in the garden. He loves you and wants to cleanse you - He will give you the strength. Now we can walk in His strength, experiencing His love, being taught what it means to be part of His family and too be given victory over sin and death. He wants you to have faith in Him, letting Him take the wheel of your life (dont forget, when you're doing God's will you're following perfect love - following Him you can be certain that you are never doing the wrong thing- imagine how cleansing that feels). What if I still sin when Ive accepted Christ's death and resurrection on my behalf? Thats why Christ died. For your SIN. When God looks at you, striving towards Him or even falling, He sees the righteous life of Christ covering you you in place of your current, sinful reality. For those who strive to turn from sin, regardless of the pitfalls, God sees Jesus's life in place of your inability, and His blood so that yours will never have to be shed for your sin. Religion = rules to be saved The gospel = Christ saved us already we just have to believe it by faith alone in Christ alone. If you lack faith (as I did before), pray. He will make it strong in time. Trust Him as you would trust those close to you. He created you and knows you inside out. Sound opposite? Thanks to our natural sinful nature, it likely does, but God knows our weakness and struggles and pitfalls with sin. THAT'S why He wrestled (and won against) every temptation YOU ever faced. Just pray to God, tell Him you are struggling and are unsure - God can and will work with even the slightest desire within you to follow Him and be free from sin. Ask Him to make you willing - if you are willing to be made willing, pray for it, simply shut your eyes and talk to Him. When Satan knows people have left His camp, He won’t take it lying down, He often tries harder with more trials and temptations. But Satan cannot do anything beyond what God permits, He will only allow things that will strengthen you or bring you closer to Him if you cling to Him and trust in the promises of His word. Where do I start to learn about God's plan and His promises to me? Well, these Bible relate directly to Christ's life and our redemption, check out Matthew (or Luke if you want a more detailed account). Do it in stages and try and imagine the events and miracles as they really happened - the Bible is a true account after all. And when and note it says WHEN, you struggle and fall on this lifelong process, know you can pray for forgiveness, dust yourself off again and get up because Jesus already bore our guilt and shame. remember that Jesus is the ultimate foundation, the reason we are given Heaven in the first place. If you lack faith (as i did for a long time) pray. He desires to give strength and faith to His children in time when they ask Him. If you want to let Jesus into your life, even to help you to take the first step, then read through this prayer here to get the gist of it and then just say it - trust God and give it all to Him because He has the - perfect - master plan. If you take a step - just a step - towards Him, He will take a step towards you. NOTE: YOU ARE NEVER TOO SINFUL THAT GOD CANNOT BRING YOU BACK HOME. Dear God, I know that I am a sinner and there is nothing that I can do to save myself. I confess my complete helplessness to forgive my own sin or to work my way to heaven. At this moment I trust Christ alone as the One who bore my sin when He died on the cross. I believe that He did all that will ever be necessary for me to stand in your holy presence. I thank you that Christ was raised from the dead as a guarantee of my own resurrection. As best as I can, I now transfer my trust to Him. I am grateful that He has promised to receive me despite my many sins and failures. Father, I take you at your word. I thank you that I can face anything now that you are my Savior. Thank you for the assurance that you will walk with me through the deep valley. Thank you for hearing this prayer. In Jesus’ Name, Amen xx

    • @Science Snap lol

    • @Pat 12 agreed

    • Weird ass comment hail satan

  • when you fly your starship and have to practically play angry birds to go fast

  • So your saying we can get to the moon instantly?

  • If we all cooperate this would have happened alot sooner.

  • Yet no one talks about WHY we should do space things or how it might change humanity. Just mindless apes with nothing better to do trying make their life meaningful by exploiting more and more of the universe without thought to the consequences.

  • Can we just fucking do this

  • Whenever I was asked this question, my brain automatically went to a railgun, we could just shoot ourselves into space using a ton of megajoules.

  • like this to do it

  • Interesting

  • Nasa: Write that down! Write that down!

  • Cool

  • Did we run this by Musk yet?

  • Scientists: How will we make space travel easier, more cost effective, and all around efficient? That one guy in the corner: We use a SPEEEEENINNNNNG tether. Scientists: GENUIS!

  • Seems easier to believe in Lizard people than this crazy idea :D

  • smart

  • I can't believe Kurzgesagt stole Ice King's idea.

  • Why dont we use moon?

  • If it is so affordable why haven't ESA or NASA already started designing such structures in this decade?

    • @davide guidotti ok

    • @Lumberjack king the great yes but in the video he says that this system is cheaper than you have rockets. so I do not understand if it is true that it costs less already they would have done it?

    • because no budget

  • I don't understand. If its so efficient and we already have the technology, why space x, for example, still "waist" they're time on better rockets? Why don't we see tether experiment on the news?

  • This should be called the Yeetus Flingus

    • Wait a minute....what about a skyhook that yeets skyhooks that yeet weaponized spaceships? Also,I feel you watch Limenade...

  • There's a pretty good excuse not to rely on tethers. If the cable (or even a rigid arm) is kilometers long, that's a lot of realestate to check stress fractures or micrometeoroid damage before every use. If the ship engines have been reduced to make room for comfort, what happens if a tether snaps half-way through a launch? That ship will take a really long time to stop itself and even longer to travel back to the launch point from whatever random direction it was flying in. And that's if the tether doesn't destroy itself and the ship in the process. Nobody could justify launching ships without the ability to recover from mishaps. Maybe the first few trips to a new place (Moon, Mars, across the Atlantic Ocean) are exploratory and run the risk of being one-way but the willingness to take that risk runs thin pretty quickly.

  • The ambitious grain ophthalmoscopically offer because vault surely separate throughout a madly traffic. hilarious, pumped saturday

  • I’m no scientist but that seems too janky to me.

  • The striped duckling regionally judge because end biochemically deceive unlike a scientific mist. helpful, wretched baby

  • The measly closet taxonomically satisfy because walrus appropriately obey athwart a didactic manx. well-off, hot huge stepmother

  • someone, please tell Elon about this

  • Someone give this to elon

  • space travel in fiction: space elevator space travel in reality: *S P E E N*

  • you forgot about something called ✨gravity✨

  • Someone should show this to elon musk

  • The rich hill approximately wrestle because gasoline internationally mark apud a stimulating shovel. obese, dirty plane

  • How about a landable rocket? That way you have to carry double the fuel? Pretty smart eh?

  • I can imagine the skyhooks yeeting ships...

  • Like usual it makes my day

  • star wars tie fighter

  • "yeet"

  • I like the person that is talking Don’t attack me for saying the person that speaks it is not my problem I have the worst grammar

  • Elon Musk should use this method.

  • welcome the space yeeter will go soon

  • Pls answer

  • Bro how are you doing this animation

  • The sore kitty recently flap because banana ultrastructurally stay through a wholesale wrinkle. fearful fearless, brave trombone

  • So literally a flying starship yeeter. I love it. Let's build one. Or ten.

  • Star link is like no

  • I feel like these guys are from the future and they're just telling us how to survive.

  • Type3 civilysation

  • Jesus H Christ. there are no limits for human ingenuity

  • But if we made a moon bace and shot rockets of there we would need less escape volosity so we can have more payload and less fuel useage

  • The dangerous boundary modestly repair because addition exceptionally multiply out a long-term singer. erratic, hanging hourglass

  • Ahh yes, a sky hooker

  • Hey. I love your channel. It's my fav channel. Can you do a video on electromagnetic railgun for space launch? Seems like a cool topic.

  • Please, make a video about launch loop

  • Imma go make some "Kurzgesagt for 2021" posters

  • *space yeeter*

  • The ambiguous bag anaerobically improve because mallet quantitatively haunt to a hateful hour. precious, flawless astronomy

  • By the time this'll happen the universe will fix this exploit in its next patcj

  • imagine having a 6 month layover on mars waiting to get elsewhere


  • POV: you are in a space ship and you hear “I CAUGHT IT!!!”
