A Space Elevator is literally an enormous elevator from the ground on Earth to a fixed location in space. People and hardware are delivered to space with a train-like elevator car, eliminating the need for expensive and dangerous rockets. The idea goes back to famed Science Fiction author Arthur C. Clarke, and more recently Robert L. Forward who worked on building some of the first real investigations on such a technology before his death in 2002.
We are decades away from building such a device, but the idea is being pursued in spite of the fact that no material known to science is strong enough to be used as a 600 mile cable from the ground to space. Yet.
It’s possible that a space elevator will be built on our moon, which would be a far simpler engineering task. Time will tell, in the meantime I hope you enjoy my Space Elevator piece and be sure to check out MUSE magazine when it hits the shelves.
