Thermal Infrared Imager (TIR) Camera Imager Bolometer -37200 The Thermal Infrared Imager (TIR) onboard the Hayabusa2 spacecraft is based on an uncooled micro-bolometer array which can obtain thermal images of a target asteroid (162173) Ryugu. The TIR is the bolometric imager with a broadband filter in the thermal infrared range (8 to 12 um). It covers the temperature range about 150 to 460 K, and has the field of view about 16.7 x 12.7 degrees, with 0.051 degree per pixel (328 x 248 pixels). TIR is modified version of Longwave Infrared Imager (LIR) of Akatsuki, also known as Venus Climate Orbiter and PLANET-C. The primary objectives of TIR are to investigate thermophysical properties of the surface of asteroids, such as porosity, grain size, and boulder abundance. Brightness temperature map of the asteroid is derived from TIR data for each time, and the brightness temperature map at each time and its forecast is obtained with the ground calibration data. Multiple observation also estimates surface roughness at each site.
