> A skyhook differs from a geostationary orbit space elevator in that a skyhook would be much shorter and would not come in contact with the surface of the Earth. A skyhook would require a suborbital launch vehicle to reach its lower end, while a space elevator would not.

- moloch-hai 4y agoAlmost all the fuel needed to reach orbit is used getting to 5 miles per second. Catching the skyhook needs none of that fuel, but only whatever is needed to get to altitude. I.e., Blue Origin's pogo stick, or Virgin Atlantic's tour bus, would suffice. The requirements on such a vehicle are massively less than for an orbital launcher.
