Description
CSST is a space-brone telescope, which will be mounted on China's planed space station. The CSST is planed to be lunched in 2024. The project is designed to observe over 17500 squared degrees in the sky during its 10 years operation and obtain over 50 M spectra of galaxies. The range of redshifts of galaxies will reach 1.5 in the Universe. The project aims to test the nature of dark energy, gravity and constrain cosmological parameters. In this talk, I will give an overview of the CSST project. I will talk about its design, some of its features as well as the challenges it is facing. After that, I will focus on the prospects of CSST in testing theories of gravity. I will overview the current status in this topic. I will compare the CSST project with current ongoing projects such as, Euclid and DESI.
