Real-life ‘skyhooks’ akin to Star Wars may soon emerge, experts say

The concept of traveling to space without the traditional means of a spacecraft or rocket might soon transition from science fiction to reality, according to some scientists who foresee the development of space elevators. This innovative technology promises to directly transport payloads from Earth to space.

Echoing scenarios depicted in the Star Wars franchise and the Japanese anime “A Certain Magical Index,” where characters and objects reach outer space without the aid of spacecraft, the idea of space elevators has captured the imagination of many. Despite its origins in fiction, experts believe that the realization of such technology could be on the horizon, with companies like SpaceX leading the charge in commercial space exploration and even beginning to offer space travel experiences to tourists.

Stephen Cohen, a professor of physics, suggested in an article for Scientific American that the disbelief surrounding space elevators as mere fantasy might soon be dispelled. He projected that space elevators could become feasible in the next twenty to thirty years. Cohen described these elevators as essentially a lengthy cable anchored at the Earth’s equator and attached to a satellite, rotating in synchrony with the planet.

While the need for space elevators in movies like Star Wars was driven by the diverse atmospheres of various planets, the motivation on Earth is to make space travel more resource-efficient and cost-effective. Such technology would revolutionize the launching of satellites, spacecraft, and astronauts, significantly lowering the barriers to entry for space exploration.

Moreover, the advent of space elevators could significantly boost the burgeoning field of space tourism, a concept that is currently in high demand among adventurous individuals and forward-thinking companies. However, despite the enthusiasm, the construction of a space elevator faces significant technological hurdles, primarily concerning the development of materials robust and economical enough for such an endeavor.

Cohen noted that while there have been advancements in creating potentially suitable materials, the achievement of a viable material solution that meets all necessary criteria and can be produced at a reasonable cost remains at least a decade away.

For the time being, the mysteries and experiences of space remain largely accessible only through the accounts of astronauts who have spent considerable time in orbit, but the dream of space elevators hints at a future where space becomes more reachable to everyone.
