摘      要：It is expected that ongoing and future space-borne planet survey missions including Transiting Exoplanet Survey Satellite(TESS),PLATO and Earth 2.0 will detect thousands of small to medium-sized planets via the transit technique,including over a hundred habitable terrestrial rocky *** conduct a detailed study of these terrestrial planets,particularly the cool ones with wide orbits,the exoplanet community has proposed various follow-up *** currently proposed European Space Agency mission Ariel is the first step for this purpose,and it is capable of characterization of planets down to warm super-Earths mainly using transmission *** NASA Large Ultraviolet/Optical/Infrared Surveyor mission proposed in the Astro2020 Decadal Survey white paper will endeavor to further identify habitable rocky planets,and is expected to launch around *** the meanwhile,China is funding a concept study of a 6 m class space telescope named Tianlin(a UV/Opt/NIR large aperture space telescope)that aims to start its operation within the next 10–15 yr and last for 5+*** will be primarily aimed at the discovery and characterization of rocky planets in the habitable zones around nearby stars and to search for potential biosignatures mainly using the direct imaging *** and emission spectroscopy at moderate to high resolution will be carried out as well on a population of exoplanets to strengthen the understanding of the formation and evolution of *** will also be utilized to perform in-depth studies of the cosmic web and early galaxies,and constrain the nature of dark matter and dark *** describe briefly the primary scientific motivations and main technical considerations based on our preliminary simulation *** find that a monolithic off-axis space telescope with primary mirror diameter larger than 6 m equipped with a high contrast coronagraph can identify water in the atmosphere of a habitable-zone Earth-like planet arou
