我们提出了一个概述和SPICA（宇宙学和天体物理学的空间红外望远镜），这是一个天文使命与低温冷却的3.5米望远镜优化中红外和远红外天文学的现状。由于其高空间分辨率和前所未有的中红外和远红外灵敏度，SPICA可以解决当前天体物理学中的一些关键问题，从宇宙的恒星形成历史到行星的形成。为了减少整个使命的质量，SPICA没有携带冷冻剂。SPICA将在环境温度下发射，并在轨道上由带有高效辐射冷却系统的机载机械冷却器冷却。这种组合使3.5米级冷却（4.5 K）望远镜在太空中。我们还描述了SPICA的技术开发计划的最近活动。SPICA的目标启动年为2010年代中期。(C)2007年由Elsevier有限公司代表空间研委会出版。
We present an overview and the current status of SPICA (Space Infrared Telescope for Cosmology and Astrophysics), which is an astronomical mission with a cryogenically cooled 3.5 m telescope optimized for mid- and far-infrared astronomy. Because of its high spatial resolution and unprecedented sensitivity in the mid- to far-infrared, SPICA can address a number of key problems in current astrophysics, ranging from the star-formation history of the universe to the formation of planets. To reduce the mass of the whole mission, SPICA carries no cryogen. SPICA will be launched at ambient temperature and cooled down on orbit by mechanical coolers on board with an efficient radiative cooling system. This combination enables a 3.5-m class cooled (4.5 K) telescope in space. We also describe recent activities of the technology development programs for SPICA. The target year of the launch of SPICA is mid 2010s. (C) 2007 Published by Elsevier Ltd on behalf of COSPAR.
