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.

@Sanja Glavasevic you are correct. But what is this? An object to make space travel easier because *We don't have good space abilities YET* This is in-efficiant if we had good space abilitties. Good cheap rockets. and so on. This is a bad idea if we had good travel capabilities. We have no need for this if we have good rockets. BUT untill then this will do. Besides it will take a long time to craft into mars.

I get your enthusiasm, but the sources and literature you used are superficial regarding important questions. In particular, Moravec and co have only superficially analysed the long-term dynamics of the spinning skyhook. This dynamics is quite complicated I think, and one should be wary whether the hook's spin energy will not be drained over time due to tidal locking or something related. Conservation of angular momentum does not prohibit such a draining: it is the sum of the orbital angular momentum and the spin angular momentum which is conserved and there can be a flow from the latter angular momentum to the former. I have not seen literature or simulations which analyse this question and with some bad luck this might be a show-stopper, no?

Isaac Arthur's video on skyhooks goes more in depth: seems "tethers unlimited" has done more research in depth.

@x -wing Sure, but this is a quantitative issue (not qualitative): how much proppelant do you need for that? What cost does it involve? On the qualitative side: can those thrusters survive those entries into the atmosphere over many cycles.

he literally explained why in this very video, he said that the tethers might still have electric or chemical thrusters to give them additional momentum.

I guess the skyhook can sling objects to higher speed if it orbits the earth's equator in a direction opposite to the earth's spin. But since our space exploration has a history of bringing satellites in equatorial orbit in the same direction as the earth's spin, I guess this scenario for the skyhook is ruled out (for safety reasons: avoid collisions at extremely high velocity). Not sure though, I'm not an expert.

@Alphahurricane except the space elevator requires materials which we either can't get or don't exist such as nuclear pasta and the space hook doesn't so a sufficiently advanced computer with a good AI would allow the sky hook to work with current materials

@x -wing as said in the video you have 60-90 second to catch a hook at mach 12 (14800 kmh or 4 kms) maybe even less time at greater speed because of spinning. its too much complicated, too much errors can occour. even a small error in our technology results in explosions as now. a space elevator is a building, the same threats of the skyhook but more simple

The earth spins meaning you would need a good orbit to be able to make use of it and sling shotting ships would most likely result in mistakes and miscalculations and such ships would need to be rescued unless having enough fuel to reach the earth or a mars colony.

A scramjet engine would be able to reach these speeds so we might not even need a rocket ship, however they don't exist yet. But it would definitely be possible to use a ramjet combined with a mass driver to seriously cut down on the weight of the rocket ship, if we can accelerate up to mach 5 with a ramjet then we don't need to carry the oxygen for all of that. The only problem would be that we'd have to carry two engine systems but we could perhaps just make the ramjet compartment a detachable booster plane which after the rockets take over would detach and land back at the spaceport. We already have plane launched rockets so this isn't really all that far out.
