China unveiled a national mid and long-term development program for space science on Tuesday, which will guide the country's planning of space science missions and space research from 2024 to 2050. The program, the first of its kind at the national level, was jointly released by the Chinese Academy of Sciences (CAS), the China National Space Administration (CNSA) and the China Manned Space Agency (CMSA).
The main reflector for the antenna system of the 40-meter-aperture radio telescope was hoisted and installed on Monday in Shigatse, Southwest China's Xizang autonomous region. Jointly developed by Shanghai Astronomical Observatory (SHAO) under the Chinese Academy of Sciences and the 39th Research Institute of China Electronics Technology Group Corporation, the radio telescope is a project constructed to offer technical support for the country's lunar and deep-space probe missions in the future.
China has constructed the world's largest transparent spherical detector 700 meters underground to capture elusive neutrinos, often dubbed "ghost particles," to unravel the secrets of the infinitesimally small and the infinitely vast in the universe. The 12-story-tall acrylic sphere with a diameter of 35.4 meters, buried deep in a granite layer of a hill in Kaiping, Jiangmen City in south China's Guangdong Province, is the core part of the Jiangmen Underground Neutrino Observatory (JUNO), a gigantic and complex scientific facility.
