Hitomi（ASTRO-H）使命是日本第六颗X射线天文卫星，由包括日本，美国，加拿大和欧洲在内的大型国际合作开发。这一使命旨在使用微量热计仪器提供E > 2 keV的最高能量分辨率，并涵盖从软X射线到伽马射线的40年能源的广泛能源范围。在2016年2月17日成功发射后，航天器于2016年3月26日失去功能，但约一个月的调试阶段提供了有关机载仪器和航天器系统的宝贵信息，包括从第一次光观测中获得的天体物理结果。本文介绍了Hitomi（ASTRO-H）使命、其能力、初始操作以及在约一个月的调试操作期间确认的仪器/航天器性能。
The Hitomi (ASTRO-H) mission is the sixth Japanese X-ray astronomy satellite developed by a large international collaboration, including Japan, USA, Canada, and Europe. The mission aimed to provide the highest energy resolution ever achieved at E > 2 keV, using a microcalorimeter instrument, and to cover a wide energy range spanning four decades in energy from soft X-rays to gamma-rays. After a successful launch on 2016 February 17, the spacecraft lost its function on 2016 March 26, but the commissioning phase for about a month provided valuable information on the on-board instruments and the spacecraft system, including astrophysical results obtained from first light observations. The paper describes the Hitomi (ASTRO-H) mission, its capabilities, the initial operation, and the instruments/spacecraft performances confirmed during the commissioning operations for about a month.
