I thought it was time to start a separate thread on this mission, launching soon
some good medium-resolution images of the spacecraft are available on JAXA digital archives http://jda.jaxa.jp/jda/p3_e.php?time=N&...mp;mission=4066 |

Out of genuine curiosity - is there some major difference in the mission management of NASA & ESA, versus the Japanese agency?
Perhaps it is the small sample size, but it seems they haven't been able to a launch any missions the past decade that don't have some serious problem. Do they lack the budget to simulate as many scenarios as NASA/ESA? Don't have as vigorous testing of components? Just plain lack of experience? At this point, with this history of failures, I have to think that these aren't isolated incidences and they are missing some critical ingredient that NASA & ESA just get right - but I don't have any idea what it could be... |

Out of genuine curiosity - is there some major difference in the mission management of NASA & ESA, versus the Japanese agency? I think I might tell something from the press here. Those JAXA(ISAS) crafts are too small. Hayabusa, for instance , had to be launched by an M5 solid fuel rocket. Alatsuki had also been designed to go on the same small M5 rocket, before IASA was merged with JAXA. No redundancy, whatsoever, unlike NASA, ESA, Russian space probes. So, I am not surprised at all. One newspaper here says that AKATSUKI may have collied with something in flight! Pandaneko (Am I still wanted?) |

Pandaneko (Am I still wanted?) Yes! I'd read the last article above as implying that the thruster may have had undetected damage on the ground, or from launch. |
