Is there a material strong enough for a space elevator?

(130000 MPa). It is the strongest material ever tested and will be strong enough to make a space elevator tether. To answer your question, single-crystal graphene is the material that can make space elevator tethers.

Is an elevator to the moon possible?

According to a study published in 2019, a lunar elevator could be the answer. A cable anchored to the lunar surface would stretch most of the 400,000km (250,000 miles) home. It couldn’t be directly attached to the Earth, due to the relative motions of the two objects, but it could terminate high in Earth orbit.

Is a moon space elevator possible?

New study suggests that a lunar space elevator could be built for about $1 billion using existing technology. Since the dawn of the space era more than six decades ago, there’s been just one way to get to the moon and back: rockets.

What is the minimum height needed for a space elevator?

Geostationary Orbit (the red and yellow objects stay exactly on top of their respective points on the surface) Remember that 36,000 km (to reach Geostationary Orbit) is the minimum height we would need to reach for a space elevator to even function.

Can we build a space elevator to the Moon?

Getting to the moon and beyond is even more expensive. So there is considerable interest in finding cheaper ways into orbit. One idea is to build a space elevator—a cable stretching from Earth to orbit that provides a way to climb into space.

Why are space elevators not built at the North Pole?

A space elevator with cables makes use of the centrifugal forces caused by the rotation of the earth. These forces’ vertical component is highest at the equator, while it is absent at the poles. If you did build a tower at the north pole, a payload would only gain height but no speed.

How would a space elevator work at the equator?

From a space elevator at the equator, a payload could be lifted to the height of a geostationary orbit. If released, the payload would stay in orbit because the necessary height and speed for an orbit are met. Share Improve this answer Follow edited Apr 2 ’19 at 9:34
