Introduction to the 500-meter spherical radio telescope (FAST) What is the abbreviation of the 500-meter spherical radio telescope?

1 and "500-meter spherical radio telescope (FAST)"-500-meter spherical radio telescope (FAST for short) are major national science and technology infrastructure construction projects built by China Academy of Sciences and Guizhou Provincial People's Government during the 11th Five-Year Plan period. This project uses the original design of China scientists and the stable and unique terrain conditions of karst depression in southern Guizhou to build a high-sensitivity giant radio telescope.

2.FAST is the largest and most powerful single-antenna radio telescope being built and planned in the world. Compared with Bonn 100m telescope, which is known as "the largest machine on the ground", the sensitivity is improved by about 10 times. Compared with the American Arecibo 305-meter telescope, which was rated as one of the top ten human projects in the 20th century before Apollo landed on the moon, its comprehensive performance was improved by about 10 times. The FAST project is sponsored by the National Astronomical Observatory of Chinese Academy of Sciences, with the participation of more than 20 universities and research institutes across the country. After 12 years of project site selection and comparison of more than 1000 depressions, Dawodang depression was finally determined as FAST site selection.

3. The 3.FAST project was approved by the National Development and Reform Commission on July 2007 10, and the foundation stone was laid on February 26, 2008, and the construction officially started on March 5, 201year. The estimated total investment of the project is 667 million yuan, mainly including site survey and excavation, active reflector, feed support, measurement and control, etc.
