Abstract
The first Japanese infrared astronomical satellite ASTRO-F is scheduled to be launched within a few years. ASTRO-F, equipped with a cooled, 67 cm telescope, is going to carry out an allsky survey at 50-200 micron, and also to make detailed observations of selected targets at 2-200 micron. The main purposes of the ASTRO-F mission are to investigate (1) birth and evolution of galaxies at early universe, (2) birth and evolution of stars, and (3) the formation process of planetary systems.
