OK, here's what Roscosmos blames for Phobos/Grunt's failure...
Sub-Par Chips (not MilSpec)
Anatoly Zak has an in depth encyclopedia of Phobos/Grunt at RussianSpaceWeb.com
In the face of all these snafus, Roscosmos is actually thinking of trying Phobos/Grunt 2.0!
Pity I have to work tonight...the Late Night Comics will have a field day with today's Phobos/Grunt News!
I guess we better Stay Tuned!
