Japanese researchers design space elevator

The video discusses the construction of a space elevator using a high-strength steel cable with carbon nanotubes. It includes plans to deploy satellites that will connect to the cable and measure 10 cm on each side. The elevator will consist of six oval-shaped cars, each 18 meters long and 7.2 meters wide. Cameras attached to the satellites will record the elevator's movement in space.
