China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has consistently produced important scientific findings since becoming fully operational in 2020. Most recently, in January, it helped an international research team find key evidence about the origin of mysterious fast radio bursts, Jiang Peng, a National People's Congress deputy and the chief engineer of the FAST, shared during the #2026TwoSessions. He added that his team is planning a major upgrade called the "Core Array", which involves building dozens of antennas, each 40 meters in diameter, to work together with the main telescope. This will dramatically improve its resolution, like turning a "sketch pencil" into a high-definition "digital camera." The project is in its final evaluation stage, with key technologies already developed and tested.
