Abstract

Large aperture space telescope is a significant scientific instrument to achieve high resolution remote sensing and high sensitivity detection. The current approach to space telescope is designed to meet the volume and mass requirements associated with a single launch vehicle, one potential approach that addresses these current challenges and achieves that future is In-Space Assembly. First of all, the development status and technologies of In-Space Assembly Telescope (ISAT) are reviewed, and some typical projects are presented to show the future application. Then, the key technologies involved are analyzed from multiple aspects: large truss structure, robot technologies and lightweight segmented mirrors. On this basis, several potential technical difficulties and challenges in the future are given, which need to be further developed to promote the capability of space technology. Finally, the future development trends and technologies of ISAT are prospected, which may provide a reference for evolution of large aperture space telescope.
