Hitomi (ASTRO-H) was an X-ray astronomical satellite launched on Feb. 17, 2016. The Hitomi satellite had both two soft X-ray telescopes with a focal length of 5.6 m and two hard X-ray telescopes with a focal length of 12 m for observation with a wide energy range. In this paper, the structural performance of Hitomi satellite on orbit was reported. On Feb.28, 2016, a 6m Extensible Optical Bench (EOB) was successfully deployed. During the deployment, the induced vibration of EOB was observed. One of the major causes was estimated to be periodic constraint changes of the EOB’s root. After the deployment, the established stiffness and alignment performance of the EOB agreed well with the predicted values. Furthermore, high shape stability of the structure could be obtained on orbit.
