Abstract Infrared Telescope in Space (IRTS) is a cryogenically cooled small infrared telescope aboard the small space platform, SFU (Space Flyer Unit). IRTS has a telescope of 15 cm diameter, which is rather small compared with other big space missions. IRTS, however, is optimized to observe extended diffuse sources with four focal plane instruments which have wide wavelength coverage from the near infrared to the submillimeter region. All instruments have been calibrated with a test cryostat, and integrated into the flight cryostat. Cooling tests of the whole IRTS system have confirmed that instruments and cryostat will perform as expected. Integration of the IRTS on the SFU will soon begin and the ground tests of the SFU system will be conducted in the coming year. The launch of the SFU will be in early 1995. The IRTS will survey the ∼10% of the sky during the three week mission and provide significant scientific results on cosmology, galactic structure, interstellar matter, stars, and solar system.
