Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more exciting: elevators. What would it take to build such a structure? Fabio Pacucci explores the physics behind modern space elevators. [Directed by Tjoff Koong Studios, narrated by Addison Anderson].

Fabio Pacucci: Yes, scientists are actually building an elevator to space

Yes, scientists are actually building an elevator to space

Space elevators could slash the cost of reaching orbit by 95%, transforming the economics of space travel and exploration.

Envision a world where a counterweight in geostationary orbit, tethered to Earth, propels us into space without rockets.

Challenges like creating a material strong enough for the tether remain, but space elevators on Mars or Moon are within reach.
