Summary
ASTRO-H (HITOMI) was a satellite for astronomy and X-Ray observation, launched by JAXA/ISASJ on February 17, 2016, from TANSC using the H-IIA 202 launch vehicle. The spacecraft measured 4.5 meters in length with a diameter of 2.2 meters and had a span of 14 meters. It was equipped with 2 HXTs, 2 HXIs, SXT-S, SXS, SXT-I, SXI, and 2 SGDs for its mission equipment. The dry mass and launch mass were both 2700 kg, powered by two deployable fixed solar arrays and batteries. ASTRO-H was manufactured by TSUK/NECTF and had an expected lifetime of over three years. Its shape was described as Oct+2 pan+boom with a radar cross-section (RCS) of 6.1649.
