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.

      Why not add in railguns to this idea? They don't need to reach 40000 km/h, they only need to reach enough speed to get to the lower end of the tether. You could easily launch something at a G force which humans can tolerate well up to the tether, likely using renewable energy. On smaller planets like the other rocky planets and the moons of gas giants, where you only need a small railgun to get to the orbit of the tether, you could get something far more useful, perhaps a shuttle to get out to Neptune's moons and then a huge railgun or a huge tether or a conventional rocket could get you out to the distant solar system. I do have a question about the propulsion of the tether anchor though. If the propulsion system is electricity, assuming it is collected via solar panel, how does it convert the electricity into a form of energy which can be used to propel it?

      I have an important question to you, because it involves your survival. This channel is fully animated. So how do you handle COPPA? I worried your videos are considered for kids, and because of subject matter, you get fined.

    I imagine people from the future finding this video and either thinking, "Well, yeah, that's how it works, but why's this only in 2D?" or "Can you believe they actually thought that would be a better solution than _______?"

    But instead we'd rather spend money on useless things and NASA is only losing money. But space exploration can only be the future of mankind.Can power sources such as solar or radiation be used?

    This cool and all but what if the ship doesn't catch the giant thing. The ships still need to have emergancy slow down system. Just saying.

    Hi! I’m a big fan. I love outer space, and I love this channel, so one month ago, as soon as the space age calendar vid came out, I sent a link to the vid to my mom and told her “mom. I’m doing really good in school this year. If I promise to fix that A-, will you get me this calendar for Christmas? It would make me so happy!” And she said “that’s an expensive calendar.. we’ll see! 😂” Just now, I asked her if she ordered it. She looked at me and said “you mean that silly video with the calendar for 10,000 years from now? I thought that was a joke.” She thought it was a joke. Immediately, I tried to get to her computer, but it was already too late. You’re out of stock. And your words echoed through my head, like the banging of a cruel gong “we’ll sell them till they’re gone, and then never again.” This is not just some made-up sob story. I am a 16 year old, and all of my money is currently trying desperately to pay for an educational trip to France (je parle Français), so I could not buy it for myself. I have high ambitions for my future and I love space. The universe calls me. I was so excited to looking at all your beautiful animation-styled space art on my wall. Please. Take pity on my soul, oh rare kind hearts of youtube. Please lift me up... please.
