摘要	The China Space Station Telescope(CSST)is primarily designed for large-scale multi-color imaging and seamless spectroscopic survey,while also accommodating observations with an integralﬁeld spectrograph(IFS),multi channel imaging,direct imaging of exoplanets,and terahertz-band observations.It is scheduled to be launched in about 2 yr.The telescope is equipped with a variety of terminal instruments.It has important scientiﬁc missions but limited observation time,so it is suggested to develop a 2.5 m coaxial telescope that will be co-orbiting with the space station.This additional telescope will mainly focus on time-domain surveys and IFS surveys.Its development budget is lower than the current 2 m off-axis telescope,CSST,but it offers superior system performance.Within the limited operational lifespan of the space station,it can signiﬁcantly enhance the existing survey efﬁciency.Like the CSST,this telescope will be able to do multi-color imaging survey,and time-domain surveys are also under consideration.
