The MUSER, as a dedicated solar radio instrument, consists of 100antennas spreading over three spiral-shaped arms with maximum baseline length ～3 km. It can obtain the imaging-spectroscopic observations of the full solar disk at about 600 frequency channels in the range of 400MHz – 15 GHz with very high resolutions and fast snapshot. Such observations provide a unique opportunity to measure solar magnetic fields, trace dynamic evolution of energetic electrons, which, in turn, will help to have better understanding of the origin of various solar activities and the basic drivers of space weather.

The Joint Science Center for China Space Station Telescope based at National Astronomical Observatories of Chinese Academy of Sciences was inaugurated on April 17, 2021.
