Three questions:
Are the CMGs more sensitive with the added shuttle mass?
Can shuttle thrusters be used to desaturate the CMGs?
Did I hear right that the undocking of the shuttle can cause saturation of the CMGs?
1: Yes, more mass
2: Yes, that is what they have been doing
3: Not exactly cause it, but lead to a saturation if they don't have the Russian computers online so they can fire the Russian thrusters for CMG desaturation.

June 15, 2007. Korolev RSC Energia - MCC, Korolev, Moscow Region.
During deployment and connection of new solar array panels on the US orbital segment of the International Space Station (ISS), there have been some glitches in the on-board computers on the ISS Russian Segment (RS).
The computers were developed and supplied by European industry under an agreement between the European Space Agency (ESA) and Roscosmos. The computer were associated with unstable operation of secondary power sources. One of the possible causes is electromagnetic noise or power surges that occurred when new solar array panels were being hooked up.
RSC Energia and NASA experts are analyzing the data. RSC Energia has established a commission to investigate the causes of the on-board computer glitches and to develop recovery procedures.
The on-board computer glitches do not affect in any way the everyday life of the ISS crew.

Funny that something affecting the saturation of gyros would be covered in so much spin from both sides.
AP: "THEY'RE ALL GOING TO DIE!"
Energia: "The crew can't even tell anything is wrong."

"There will be "big" press-conference at Mission Control Center (MCC-M) for our media at 14:00 UK,"
Will this be on NASA TV, it's 14:00 now here, or is 14:00 GMT the proper time.
Cheers

No. Notice the "our media" in the sentence. It refers to Russian media only.

Some irresponsible journalism from ABC now heading out on the wire to all ABC stations...
"Russians: Possible 'Fatal Flaw' in Space Station
Russian Sources Tell ABC News They Suspect Americans Damaged Computers
rest of it here:
http://abcnews.go.com/Technology/story?id=3281714&page=1Making me a little nauseous. Especially the part : "The story is getting almost no coverage in the Russian media."
UGH!

For the love of all that is good and sane, stay away from the ABC News "Talk Back" comment section. The stupidity in there is thick and heavy.

My contacts are growing increasingly skeptical of the 'sour power' hypothesis. They tell me -- I can't confirm it -- that the troubles were detected PRIOR to the new power source coming on line. Other varieties of EMI and grounding problems remain viable, even more attractive.

If its accurate that the computer is now isolated from the US Segment power, then its difficult to see how the cause could be there. I of course know there could be radiative (EMI), but considering its space hardware it would have to be able to withstand at least a certain level of this. Even stuff for home and office use on Earth has to pass fairly stiff EMC testing, space hardware is bound to be even stricter.

Just treat it as a comedy sideshow.
I have to say that I like the way the article just ends, there is no real flow to the story.

No, These stories are what the general public eats for breakfast! It's aiding in the destruction of interest in space and must not be accepted.

Jim, are there any more details you can possibly give us about what you know or what you've heard. Maybe on L2 if you think it'd be better. I'm really intrigued to know what the score is.

Anyone else noticing this frankly scary sounding sound on NASA TV?
That can't be the video.
Sounds like wind, distortion, and some chorus of something.

Prior would take the S3/S4 out of the equation then. This gets more interesting by the moment.
