Final testing for Asia's largest radio telescope

Last-minute checks are being carried out on Asia’s largest radio telescope, and are schedule to be completed in Shanghai on Sunday.

Weighing over 2600 tons, the rotatable telescope has a 130-meter long track, to support horizontal movement.

The width of the track is accurate to within just point five millimeters... and the telescope itself has over 1100 precision mechanisms.

Construction began in 2009. The telescope will be used for looking into deep space, and will also play an important part in China’s Lunar Exploration Program.
