In the year 2050, a space elevator is expected to become a reality, completely overturning the image of space travel. The elevator will travel to space by a vehicle called a "climber" on a single cable that extends from the earth base, Earthport, on the ground to the end the destination 96,000 km away from earth. This is approximately eight times the diameter of the Earth. How was the concept of the space elevator born, and what’s the construction plan? The time where you can easily travel to space is just around the corner.
