China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST) completed the installation of six domestically developed steel cables on Monday in Pingtang, southwest China's Guizhou Province, fully replacing the core components of its cable-driven suspension system.
The six cables act as the "muscles" of the telescope, supporting its 30-tonne cabin — known as its "eye" — and enabling ultra-precise, real-time positioning and tracking at a height of 140 meters across a range of 206 meters.
