    Japan is in trouble with it's satellites lately.
    IGS 1B malfunctioned and is coming down since 2007, and potentially a sort of a 
    re-entry hazard for 2012 depending on how much fuel is still in it.
    IGS R2 malfunctioned late 2010.
    And now this satellite (which is in an 697 x 694 km orbit, higher than the 
    IGS-es, so unlike IGS 1B which is now at 455 km altitude, not a direct decay 
    threath in the near future).
