Work on the nearly 1.2-billion-yuan ($180 million) project started in 2011, and the installation of the telescope's main structure -- a 4,450-panel reflector as large as 30 football pitches -- was finished in early July this year. FAST's tasks include survey of neutral hydrogen in the space, observation of pulsars as well as spacecraft tracking and communications. 皇冠体育app achieved major breakthroughs in scientific and technological development in 2016.
