Drone footage: China building world’s largest 500-meter radio telescope
China is assembling what has been hailed as the world’s largest radio telescope, state media reported. The 500-meter tool will boast a dish the size of 30 football pitches, overtaking Puerto Rico’s Arecibo Observatory, “only” 305 meters in diameter .
With a perimeter of about 1.6km, it will take up to 40 minutes to walk around the single-aperture spherical telescope, which is called “FAST”. It will be constructed deep in the mountains of the southwestern Guizhou Province, built on a naturally formed bowl-shaped valley, Xinhua reports.
The construction of the highly sensitive telescope began in March 2011 and is due to be completed next year. On Thursday, technicians already began attaching 4,450 triangular-shaped panels to the telescope’s reflector. To overlook the whole reflector, visitors will reportedly have to climb up to the top of one of the hills. An observation platform is currently said to be under construction.
