    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.

    tethers are about as risky as being catapulted into the sky 1000km and landing in the spot you wanted. You can do the math for accuracy but do you trust the precision. Not only would you land but you would be refired and hope to land on your next destination for your "interstellar journey". For our tech the flinging would save on fuel but hopefully before we need to go through with building some system like this we find other ways to travel through our solar system

    your animation is wrong on the 4:15 timeline it would hit the tether and push it back up to speed not get caught by the tether and released.

    Fascinating but many unanswered questions. Could we build a durable cable with current materials? How complex would it be to build and to deploy in orbit? What if it spun out of control and crashed? Are there any other safety risks? What if it got hijacked by people with malicious intent, could it be used as a weapon?

    This is really interesting, and has left me wanting to know why it isn't a bigger talking point/closer to a practical solution if it's "that easy" and effective? Would've loved to see the video touch on that.

    imagine missing the tether and now drifting into the emptiness and darkness of the space.
    that would be pretty scary

  • Phyzzius

    It looks like a cool idea, but it's never going to happen. It's an engineering nightmare. First you would have to build the thing in space, using conventional rockets. Then you have to start spinning the thing, making sure you don't hit the literally thousands of satellites flying around earth. Even if you would manage all that, you *still* need a rocket to get your ship to an altitude to hook up with this thing, a maneuver which would be so difficult, I doubt anyone would be willing to try it (mind you, they take days to maneuver and dock a resupply ship to the ISS). But the fact you still need a rocket makes this a useless idea, more than two thirds of the delta-v you need to achieve escape velocity is to get into earth orbit. Why would you build such a complicated thing only to make the last bit of the trip more efficient? That effort is better put into building a refuelling station in orbit, which will also give your rocket more delta-v, but with much more manageable engineering challenges than this idea imho...

    The Incoming ships needed to add sufficient momentum to the tether would have to be vessels returning from the moon with mined materials. A lot of non tethered trips required first, yall will be dead by then
