An economically sustainable mean of space transport

The future of space travel is not rockets, essentially large fuel tanks capable of carrying only a tiny amount of payload. Getting things into space with rockets is inefficient and too expensive.

Space elevators could be used to go into space with less fuel and more load, but at the moment they are only science fiction.

A simpler alternative that we can really build is the Skyhook or Space Hook.

It is simply a huge rope, hundreds or thousands of kilometers long, connected and held in place by a counterweight, both placed in space.

The long cable can be used by spacecraft as a ladder to reach greater heights and speeds.

And it works even better if it rotates. The end of the rotating cable slows down when it is closer to the ground, in order to lock the…
