Japan's Space Agency Loses Contact With New X-Ray Telescope Satellite "Hitomi"

As carried here by the San Francisco Chronicle, The Associated Press reports that Japanese space agency JAXA reports that it has lost contact with its new satellite "Hitomi," deployed last month and designed to explore deep space with X-ray telescopes. The AP story linked quotes Harvard astronomer Jonathan McDowell, who surmises that an "energetic event" has sent the craft into a tumble. The agency's release on the failure is terse, but leaves some room for hope: The Japan Aerospace Exploration Agency (JAXA) found that communication with the X-ray Astronomy Satellite âoeHitomiâ (ASTRO-H), launched on February 17, 2016 (JST), failed from the start of its operation originally scheduled at 16:40, Saturday March 26 (JST). Up to now, JAXA has not been able to figure out the state of health of the satellite. While the cause of communication failure is under investigation, JAXA received short signal from the satellite, and is working for recovery.

      The odds of it being a MMOD, especially given how little time it's been in orbit, is very low. Conversely, the fact that broke up so early in the mission would reinforce a hardware failure of some kind (battery explosion or cryo system overpressure as you said).

      cryo system overpressure.

      That does surprise me as a possibility, as fitting bursting discs and such-like venting systems is pretty common in ground systems. But I guess that may increase the number of possible points of failure, which would change the calculus of risk.

      Anyone would think it was rocket science!
