ASTRO-F（IRIS）是日本第一颗专门用于红外天文学的卫星。该项目的主要目的是通过2至200微米波长范围的深宽场调查，研究早期宇宙中星系的诞生和演变。空间分辨率和点源灵敏度分别与孔径衍射极限和自然背景和/或混淆极限的空间分辨率和点源灵敏度几乎相同。在远红外波段，ASTRO-F将进行与红外天文卫星一样的全天观测，其灵敏度高几十倍，空间分辨率高几倍。在近红外和中红外波段，将对预先选定的天空部分进行大面积天空调查。除了这些光度测量外，还提供所有波段的低分辨率光谱测量能力。ASTRO-F使命将为FIRST和NGST等下一代先进观测站建立一个基本数据库，并将凭借其广阔的天空覆盖范围补充SIRTF使命。M-V火箭定于2004年2月或3月发射。
ASTRO-F (IRIS) is the first Japanese satellite dedicated to infrared astronomy. The primary purpose of this project is to investigate the birth and evolution of galaxies in the early universe through deep, wide-field surveys at wavelengths ranging from 2 to 200 microns. The spatial resolution and the point source sensitivity are nearly the same as those of the aperture diffraction limit and the natural background and/or confusion limit, respectively. In the far-infrared wavelength band, ASTRO-Fwill conduct an all-sky survey like the IRAS survey with several tens of times higher sensitivity and several times better spatial resolution. In the nearand mid-infrared, wide area sky-surveys will be conducted over pre-selected portions of the sky. In addition to these photometric surveys, low-resolution spectroscopic capabilities are available for all wavelength bands. The ASTRO-F mission will produce a fundamental database for the next generation of advanced observatories, for example FIRST, and NGST, and will complement the SIRTF mission by virtue of its wide sky coverage. The launch by an M-V rocket is scheduled for February or March of 2004.
