Space infrared mission in Japan

Open publisher page 0 citations

Abstract

A space infrared astronomy program in Japan is reviewed. The first space infrared telescope, IRTS (Infrared Telescope in Space) will be launched in February of 1994. The IRTS is a small mission onboard the small space platform, SFU and is optimized to observed diffuse infrared emission. Based on the experiences of IRTS, a new space infrared mission, IRIS (Infrared Imaging Surveyor) is now being proposed. The IRIS will be launched by MV rocket which is now under development in ISAS. The IRIS is a new technology telescope which uses mechanical cooler and radiative cooling. With use of large format arrays and 70 cm aperture telescope, new discoveries on cosmology, galaxies, stars, and planetary systems are expected.
