Space Elevator – Science Fiction or the Future of Mankind?
Kurzgesagt – In a Nutshell・2 minutes read
A space elevator could revolutionize space exploration by significantly reducing costs and making it more accessible, potentially recouping its $20 billion construction cost after launching one million tons, with challenges in developing a strong, lightweight tether material and powering the climber.
Insights
- The implementation of a space elevator has the potential to drastically reduce the cost of launching cargo into space, from $20,000 per kilogram to $200 per kilogram, thereby making space exploration more economically feasible for humans.
- Building a space elevator poses significant challenges such as creating a durable, lightweight tether material, ensuring a stable power source for the climber, and managing potential risks associated with a tether breakage, highlighting the complex engineering and material science requirements involved in this revolutionary concept.

Revolutionizing Space Exploration: The Space Elevator
- The concept of a space elevator could revolutionize space exploration by significantly reducing costs, making it more accessible to humans.
- Rockets currently cost $20,000 per kilogram to launch cargo into space, but a space elevator could lower this cost to $200 per kilogram, potentially recouping its $20 billion construction cost after launching one million tons.
- A space elevator would consist of four main components: the tether, anchor, counterweight, and climber, with the tether extending from Earth to space, supported by a counterweight above 36,000 kilometers.
- Challenges in building a space elevator include developing a strong, lightweight tether material that can withstand environmental factors, powering the climber, and sourcing raw materials, with potential risks if the tether were to break.
