How much would a skyhook cost?

Currently, each launch of this rocket costs around $115,000,000. This cost allows about 64 tonnes of stuff to be delivered to low-Earth orbit (which is about the altitude of the ISS, 250 miles, or 400 km).

How feasible is a skyhook?

The construction of an orbital skyhook is shown to be feasible with current materials. It is a fully reusable launch system with very high propellant efficiency and could provide the launch capability needed for future planetary science missions.

Why does nobody use the Skyhook?

Kareem Abdul-Jabbar on why players don’t use the skyhook “The reason that young kids today learn how to shoot hook shots is because everybody is so enamored with the 3-point shot. So the kids don’t want two points. They don’t want to work with their back to the basket.

What is Skyhook and space elevator?

A skyhook is a proposed momentum exchange tether that aims to reduce the cost of placing payloads into low Earth orbit. 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.

How does the Skyhook work?

Here’s how Skyhook worked: From the air-dropped package, the officer on the ground used a helium balloon to lift a 500-foot cable into the air. Then he would strap himself to a harness connected to the other end of the cable, and sit with the wind to his back and arms crossed.

Should we build a space elevator?

A space elevator is possible with today’s technology, researchers say (we just need to dangle it off the moon) Space elevators would dramatically reduce the cost of reaching space but have never been technologically feasible.

Is the Skyhook cost competitive with an elevator?

An engineer speculated in 1994 that the skyhook could be cost competitive with what is realistically thought to be achievable using a space elevator. In 2000 and 2001, Boeing Phantom Works, with a grant from NASA Institute for Advanced Concepts, performed a detailed study of the engineering and commercial feasibility of various skyhook designs.

How far away from the Space Shuttle is the Skyhook?

The Italian satellite was deployed to a distance of 19.7 km (12.2 mi) from the Space Shuttle. An engineer speculated in 1994 that the skyhook could be cost competitive with what is realistically thought to be achievable using a space elevator.

Why don’t we build Skyhooks on the Moon?

The lower gravity of the moon, lack of atmosphere, and lack of human populations mean that a skyhook in lunar orbit should be far more feasible to build. Lunar resources could be used to build larger space stations and space vehicles.

Is it possible to build a space elevator on Earth?

The cable thickness is adjusted based on tension, it has its maximum at a geostationary orbit and the minimum on the ground. Available materials are not strong enough to make an Earth space elevator practical. Some sources have speculated that future advances in carbon nanotubes (CNTs) could lead to a practical design.
