Space Elevator From the Moon to Geostationary Earth Orbit

• https://www.nextbigfuture.com, by Brian Wang

We do not have materials for a space elevator from the Earth to Geostationary orbit. The moon spaceline would be longer but would only have to overcome the moon's gravity.

The biggest hurdle to mankind's expansion throughout the Solar System is the prohibitive cost of escaping Earth's gravitational pull. In its many forms the space elevator provides a way to circumvent this cost, allowing payloads to traverse along a cable extending from Earth to orbit. However, modern materials are not strong enough to build a cable capable of supporting its own weight.

The Spaceline is a new analysis of lunar space elevators. By extending a line, anchored on the moon, to deep within Earth's gravity well, we can construct a stable, traversable cable allowing free movement from the vicinity of Earth to the Moon's surface. With current materials, it is feasible to build a cable extending to close to the height of geostationary orbit, allowing easy traversal and construction between the Earth and the Moon.
