Japan's Space Agency Loses Contact With New X-Ray Telescope Satellite "Hitomi" 77

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.

    I don't know about that satellite, but when I'm floating around in a vacuum and I have an energetic event, I feel pretty messed up.

    Sourced from the competition of things you may have read:

    Oh this is very very bad. From @spacetrackorg "Breakup Notification: [...] ASTRO H at approx 0820z, 26 Mar 16: 5 associated pieces .."

    Suspected causes are a MMOD hit, battery explosion or cryo system overpressure. Suggestoin that "It's too early to write the satellite's obituary", but any good news is very unlikely.

      I'm guessing Hitomi got taken out by the Mobile Fortresses.

      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).

      For a change, this is pretty much exactly what I had guessed upon seeing an unfamiliar acronym.

    • Bummer about the mission.

      I wonder if McDowell actually got permission to post that twit --- the ToU of space-track.org seem pretty strict:

      The User agrees not to transfer any data or technical information received from this website, or other U.S. Government source, including the analysis of data, to any other entity without prior express approval. See, 10 USC 2274(c)(2).

    • 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!

      One of the reasons I use SoylentNews - they actually bothered to use a fixed version of Slash that doesn't have these problems.

        That might be a failing on your part. €, £, $, and as this is Japan, ¥. Or did you want ©, ñ, or ü?

        < © — €

          Nope. I type the £ symbol on my keyboard, into a standard browser, that works on EVERY OTHER WEBSITE IN THE WORLD, even "just works" in Notepad, etc. And I get that shit.

            What button is that? Try using the AltGr keys. In Windows, use the US International (though I think others work) and they insert it just fine. (I've done it, many times.)

            The other poster said I used the HTML entities. That is only partially true. lt gt mdash ndash are entities, as is euro. The others are inserted with the keyboard.

    Japanese galaxy porn is the worst anyway, since they will censor the best parts.

Think of it! With VLSI we can pack 100 ENIACs in 1 sq. cm.!
