Japanese Company Plans To Build A Space Elevator By 2050

Japanese company Obayashi has declared that they will have a space elevator assembled by 2050. The elevator will spread 96,000 km (60,000 mi) into space and will transport people and shipment to a new space station. It will also work as a port to transport astronauts to Mars and beyond.

“The construction process consists of deploying the cable and constructing the facilities. It is necessary to analyze the cable dynamics in order to estimate the characteristics of the cable, counter-weight, facilities and climbers, and in order to determine the construction procedures.

Parameters for the cable dynamics include tension, displacement and elongation of the cable due to ascending climbers, masses of counter-weight and cable, wind, and fixed loads of facilities.

With the help of a computer simulation of the equations of motion, we designed the system and determined the construction process.” ~ Obayashi

  1. Arthur C. Clarke proposed this system back in the 1960s!!

    1. No :) It was largely inspired by the works published at the time :)
