any new messages about russia computer ?
No. Chris will post in this thread if there's anymore development on the situation. There's no need to ask. If there's any updates, it will be posted in this thread.

Thanks , I hear crew must left ISS if they can't repair computer .

I don't think it was fair of NASA TV to show exclusive images of the Russian computers just then!

I certainly hope this crew is not "lost in space"

A plan, A backup plan, a backup to that and more.
Don't under estimate the tricks both Roscosmos and NASA can pull out of their hats. I fully expect either a fix, workaround or other solution to be in place before the weekend is over.

Me too and I hope it gets thrown all over the faces of the doomsayers.

The Nasa engineers are doing their jobs, how about the NASA pr. folks
This should be discredited before it gets out of hand.
Just a curiosity question, but have there been any new links to those computers that were installed on previous assembly missions and just now became active or increase functionality with the new assemblies.
Also , anyone if they know if they are working on any way to get telemetry to the Russian Engineers while the station is outside of ground station coverage, maybe using the NASA trds network.
I can't believe there is so much isolation between the US segements and the Russian segements.

According to Interfax Energia is pondering launching a Progress on July, 23rd with new power supplies for computers.

Would that mean demanning the station until than.
Hope not , but thats a long time to go without attitude control and reduce scrubbing.

A bit of goodness out of CNN at least: while the anchors are busy with the "they're all gonna die" story, Miles Obrien, their space correspondent, is talking about it not being that serious as there are work-arounds and fixes that can be done.

If this really is a noise or grounding issue, I should tell you that these types of problems are notoriously hard to track down. Tracing ground loops can be thought of like a Fraternity hazing for double-E's. This could be complicated on the station by the inability to just shut things down and unplug at will, and the apparent lack of double-E's or electronics techs on the crew.
I hope they get it understood quickly, and in that light I hope it's NOT a grounding or noise problem.

Abandonning the station, if attitude control is lost, would probably be permanent. I can't imagine NASA or RSA sending up crews to a station that's tumbling out of control. Seems like it would be too dangerous.
No, there's plenty of time to work on solutions before we start talking about abandonning the station.

It would be a bad decision, it would force congressional oversight, the mars global surveryer software snafu would certainly be brought up.
If its at all possible, I would hope they don't resort to that.
Is it better to watch this thread or the day 8 thread in l2.

Don't mean to sound like I'm beating a dead horse, but in retrospect, are we sure the CMG saturation during install was simply an error on someone's part (not desaturating before the install, as was reported), or a symptom of a failure in the Russian attitude control system? It just sounds a bit too coincidental to me.
EDIT: JimO's comments got me thinking a bit more about that...

There are currently two Progress available to desaturate the CMGs that are independant of the troubled computers. With the CMGs desaturated attitude can be maintained. The biggest problem is the Atlantis demate which gives the station a large momentum change that will likely saturate the CMGs and will require a fairly large correction from the Progress. Once that is handled they should be in an OK config for a short time. Certainly until replacements can be flown up on Jul 23. If absolutely necessary they can evacuate at any time via the Soyus lifeboat.

Nikolai Sevastianov, president of Energia, told that the cause of "secondary power supplies" failure was the static electrical discharge when astronauts were working outside.

Edited minor spelling.
