摘要

SPICA (SPace Infrared telescope for Cosmology and Astrophysics) was selected for study as a mission of opportunity within the science programme Cosmic Vision 2015-2025 of the European Space Agency, with a planned launch in 2017. Observing in the 5 – 210 micron waveband, one of its major goals is the discovery of the origins of planets and galaxies. ESA's contribution is the provision of the SPICA Telescope Assembly (STA) featuring a 3.5 m primary mirror cooled to < 5K, and instrument engineering and management of a nationally funded European FIR instrument (SAFARI) as part of SPICA's payload. SAFARI is an imaging spectrometer operating at 30 – 210 micron, baselined as a Mach-Zehnder (MZ) Fourier Transform Spectrometer (FTS). An internal ESA study has been carried out to address the specific challenges associated in particular with STA and SAFARI, taking into account resource margins and interface specifications driven by the overall spacecraft design. This paper provides a summary of the preliminary results achieved during this study.
