Abstract

Abstract

The aperture and structural configuration extremely determine the technical difficulty and economic cost of a spaceborne telescope. In order to realize higher spatial resolution and capacity of acquisition of information, the aperture of primary mirror of space telescope abroad is getting larger and larger. From the 2.4 m aperture of the Hubble Space Telescope(HST), to the 4 m aperture of the New World Observer(NWO), up until to the 8-m aperture of the Advanced Technology Large Aperture Space Telescope(ATLAST), all without exception embodies pursuing the high capacity of ultra-large aperture observation. Monolithic primary mirror is becoming the first choice of ultra-large aperture space telescope by right of its technical reliability and economical efficiency. Through analysis and discussion on developing ultra-large aperture space telescopes abroad, the key techniques and trend of development of ultra-large aperture primary mirror are investigated. Then we proposed the assumption to build a 3.5 m aperture space telescope with a monolithic primary mirror based on the state-of-art capacity of lunching and optical fabrication in China.
