The University of Tokyo), Bunkyo-ku, Tokyo, Japan, SPICA (SPace Infrared telescope for Cosmology and Astrophysics) is a future mid- and far-infrared astronomy mission after AKARI, Spitzer and Herschel, with a 2.5 m telescope actively cooled below 8 K. Thanks to the cryogenically-cooled telescope as well as the advanced instrument technologies, SPICA provides unprecedented high sensitivity in spectroscopy, photometry and polarimetry. In particular SPICA enables detailed spectroscopy with continuous coverage from mid- to far-infrared ranges for the first time. SPICA has the following key science objectives: (1) revealing the rise and fall of galaxy formation over cosmic time, (2) understanding star formation from filaments to galaxies, and (3) tracing the gas, dust and ice in planet forming systems. The definition of the previous SPICA mission has been revisited since 2014, and now, new SPICA is re-defined as an international project between JAXA and ESA, with a combination of a strategic L-class mission of JAXA and a Cosmic Vision M-class mission of ESA. If selected, SPICA will launch in the late 2020s and operate for a goal lifetime of 5 years. SPICA carries onboard the mid-infrared instrument SMI as well as the far-infrared instruments SAFARI-SPEC and -POL; the former is the Japanese-led instrument developed and managed by a university consortium. In this paper, we describe the current status of the SPICA project, the SPICA science goals, and the conceptual design of SMI, mostly focusing on the importance of the AKARI heritage from scientific and technical points of view., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730026007, レポート番号: JAXA-SP-17-009E}, pages = {53--58}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {New SPICA: the next crucial step after AKARI for future mid- and far-infrared astronomy}, volume = {JAXA-SP-17-009E}, year = {2018} }
