PROJECT DESCRIPTION

The world’s largest single-aperture telescope. The active reflector system of FAST is a 500m aperture and 300m radius spherical crown composed of its primary supporting structure, actuator, backing structure and reflector panels. FAST was assembled in a mountainous region with complicated terrain and is also the largest space structure ever to have been built. 

Judge's comment:

Building the world’s largest space frame structure in a remote, mountainous region is truly impressive feat. The judges were impressed by the construction challenges overcome to install a pair of 500m diameter compression rings on columns varying in height by 50m and then accurately placing 6,670 steel cables to form a geodesic triangular grid. A remarkable engineering accomplishment.
