In the video, the construction process of the impressive world’s largest Radio Telescope, in SW China, created to hunt aliens…
The building of the 500-meter aperture Spherical Radio Telescope (FAST) is progressing well in southwest China’s Guizhou Province with reflector units being installed.
FAST will effectively help mankind better probe the universe after completion in 2016, according to scientists.
The installation of 4,450 reflector units underway is a complicated process which will affect the accuracy of the telescope, whose dish is the size of 30 football grounds.
Each panel is an equilateral triangle with a side length of 11 meters. Cables are fixed to the back of each panel so that it can change positions with an accuracy of 1 mm, ensuring the telescope to receive from different angles.
The telescope is unique in its design with three active layers. The first is made up of over 2,000 bars, while the second comprises steel cables and over 4,000 reflector units. The third consists of a feed cabin structure which can move on the reflector units.
