• Hitomi - . Payload: ASTRO-H. Nation: Japan. Class: Astronomy. Type: X-ray astronomy satellite. USAF Sat Cat: 41337 . COSPAR: 2016-012A. Apogee: 580 km (360 mi). Perigee: 565 km (351 mi). Inclination: 31.00 deg.

  ASTRO-H X-ray astronomy observatory rode H2A No. 30 to a low Earth orbit. It carried an array of five X-ray telescopes. Hitomi suffered a major anomaly on Mar 25 while observing the quasar Markarian 205. At 1910 UTC the satellite started tumbling and then at 0140 UTC Mar 26 the spacecraft partly disintegrated. US tracking found eleven debris objects in orbit. During the next scheduled pass at 0740 UTC, JAXA received only a short burst from the radio beacon and nothing more; three more such beacon detections were obtained up to Mar 28, when the spacecraft fell silent. Ground-based optical observations showed that at least two of the debris objects, 2016-012A and 012L, were bright and tumbling several times a minute. 2016-012A was probably the main spacecraft bus. It's possible that 2016-012L was the extensible optical bench with the HXI cameras, or part of the solar panels.
