Paper Abstract

The infrared space telescope SPICA, Space Infrared Telescope for Cosmology and Astrophysics, is a next-generation astronomical project of the Japanese Aerospace Exploration Agency (JAXA), which features a 3m-class and 6K cryogenically- cooled space telescope. This paper outlines the current status for the preliminary structural design of the SPICA payload module. Dedicated studies were conducted for key technologies to enhance the design accuracy of the SPICA cryogenic assembly and mitigate the development risk. One of the results is described in this paper for the concept of the on-orbit truss separation mechanisms, which aim to both reduce the heat load from the main truss assembly and isolate the micro-vibration by changing the natural frequency of the spacecraft.
