1,000km Cable to the Stars – The Skyhook

Going into space is hard. At the moment, it is like climbing a mountain on a one-wheeled bicycle. With a bag full of explosives. Too slow, you can not transport many things, and you may even die. A rocket must reach speeds of about 40,000 km / h to leave Earth. To achieve that speed, missiles are mostly fuel containers and a very small payload. This is not good if you want to go to other planets because you need a lot of things if you want to survive and maybe even come back. So is there a way to get into space with less fuel and more load? One good thing that solved most of our transportation problems on Earth is what we call infrastructure. Be it car routes, boat ports, or train tracks. We made it easier to travel. We can apply the same solution for space travel. Spatial infrastructure will make it easier and cheaper to go into orbit and to the Moon, Mars and beyond.

Very well, but what exactly is spatial infrastructure? Unlike a terrestrial elevator for space, which is currently just a fabrication, there is a simple but promising technology that does not require new science, nor magical materials or large investments. And it has been successfully tested in orbit already. A cable and a weight known as links. The concept is so simple; it is astonishing. What if we put these links, hundreds or thousands of miles long – in space, and if we had spaceships which would use these links as a ladder to climb to greater heights and gain speed? This concept is known as Skyhook.

Works even better if rotated. A counterweight holds a long cable in place as it rotates in a circle. The rotating link decelerates its tip depending on the down position and accelerates it to the top like a catapult. This means that energy can be transferred from the connection and gain a massive boost when it is released, more or less for free, equal to twice the rotational speed of the connection. There are specialized fibers that can withstand it the extraordinary stress that the Skyhook would face. To protect our connection from games with rocks and meteors, we can wrap it with a web of fibers.

Since our Skyhook would pass through the same place many times a day, this would enable reusable missiles to reach it. Certainly not that easy. At its lowest point, the link travels straight atmosphere at a speed of 12,000 km / h. Due to the Earth's atmosphere, we cannot lower the Skyhook much because it would be heated by friction with the air. Therefore it will dive to a height of 80 to 150 kilometers and not below.

To achieve this, we need space machines which can go as far as the connection. Although this is by no means easy, it is still much cheaper than sending a tin can, filled with rocket fuel, to move at 40,000 km / h. Capturing the top will be a challenge as well. It has a short time of only 60 to 90 seconds to find something small in the sky, which moves rapidly Mak 12. To make this easier, the yeast could have a kind of fishing line a kilometer long with a navigation drone which helps the probe connect.

Another challenge is keeping our Skyhook in orbit. The more ships that tie to it and pull themselves up, they use the momentum that holds it in place. If we do nothing, it will slow down and fall into the atmosphere. And here, we can trick the universe a bit. Skyhooku is the battery of orbital energy. It is possible to balance round trips. Ships coming bringing people and materials to Earth add energy to the connection, which can give it to other ships which depart for space. This way, the connection does not lose energy. The more we use it, the cheaper it becomes. If still energy with each boost, we can renew it with small electric or chemical motors who constantly correct the position of the connection. A set of connections, one near Earth and one near Mars, could make interplanetary travel simple, direct and low cost compared to missiles. The Earth connection would stay in low orbit to get people and containers and you "threw" on Mars.

The Martian connection catches them and stops them from landing on the surface. In the opposite direction, the connection could catch a vehicle which travels in the thin atmosphere of Mars at a speed of only 1000km / h not even faster than commercial planes on Earth, and throws them back to Earth where it can be caught and lowered. Connections could shorten interplanetary travel, from 9 months to 5 or even 3, and reduce the amount of missiles by about 84 to 96%.

Even better, people can travel in luxury, since we can also send people with relative comfort. Cable Travel can be a first class trip to Mars! Together, the Earth-Mars link could be the primary bone of economic transport. the primary bone of economic transport. This would make cross-space travel possible and affordable. But let’s go further. Starting from the lower Martian orbit, a link can lead spacecraft to the asteroid belt. The first spacecraft to land on the asteroid it would need missiles to slow it down to its destination. Subsequent arrivals would find other pending connections to pick them up and send them back for free. Going to cheap asteroids is one of the key components in the opening up of solar system resources.

Precious metals and valuable minerals can be extracted and transported to Mars just weeks after being cut by the asteroid. This would be the most perfect basis for building our interplanetary civilization. But why stop there? The moons of Mars are very valuable. No other Moon in solar orbit orbits so close to its own planet. Phobos is so heavy we wouldn’t need to slow down, making it the perfect capture point for interpersonal super-connections almost under 6000km long. The lowest point would fly slightly above the surface of Mars and would be easy to catch. The upper tip can fly ships up to Jupiter and Saturn. The same super-connection can also bring the solar system closer. Venus and Mercury are just a throw away. Unlike Mars, they have a lot of solar energy and are full of minerals. In the long run, nothing stops humanity from building one propulsion transport network for planets near the Martian moons- The connections are relatively inexpensive and maintainable, which can make the space travel free also for the whole part of the solar system open to exploration and acquisition.

Considering that we have the technology to build it today there is no reason to wait any longer. Parts of the Solar System are far away, but may be closer. Since we are talking about things that are difficult to achieve, but that need to be: Knowledge. (Advertisement starts) .
