Live coverage of what should be a less eventful flight day, although we can expect some wiggles on the P6 and some daft questions if PAO let some of the non-specific space media if they are on the media event to the crew.

L2 - and that is the latest.
Also another false fire alarm about an hour ago.

From Holly Ridings, ISS Flight Director, lots of good progress on getting the Russian computers back to operation. Still clean up steps to do, root cause analysis, re-powering of Soyuz to ISS power, and other steps to complete.

According to CNN, Reuters, and several other outlets, this may be a big day trying to get computers back up and running or else abandon the station...
What exactly is going on? How serious is it compared to the media hype?

This is of course a replay from earlier today.

Hi guys thanks for the great coverage but can anyone tell me what the status is of the P6 retract as far as bays still deployed and also if they have the SARJ rolling yet on S4. I would really appreciate it. Thanks.

Ahh media :laugh:
The computers are up and running but Russian ground control only has one communications path open and not three.
The big question is what caused them to all crash?

No confirmed plan at this time for Atlantis to stay docked the extra day - NASA TV.

But it wasn't in this thread yet (well, that I saw), and I think it should be since it's one of the main issues from yesterday.
Anyway, glad they're starting to get on top of it. Hopefully there will be no more negative surprises from this group of systems.

Last we heard it was down to 18 bays to go (which allows SARJ rotation). There are notes that some retraction was done a number of hours ago, but we'll confirm status as we go.

Maybe they're still running Windows ME?

I would expect Russian computers to boot in Russian. So I would think not.

Getting one lane of SM computers (provided by ESA, search on Data Management System (DMS-R) for tech details) back up is no big deal, especially considering that normal reboot is automatic and brings all three lanes back up -- not a single lane. KEEPING a lane up for several days straight is the challenge, since whatever seems to be happening is sporadic but fatal to the computers. Diagnosing it, and immunizing against it -- that is what faces them now.
This is not a 'normal' problem and deserves the attention it is getting (as opposed to the thermal blanket
).

This is not what I got from the briefing last night. They said that *normally* the reboot is automatic and brings all three lanes back up, but that this was automatically attempted several times and failed each time, bringing no lanes back up.

So the challenge facing them now is finding the root causes of the computer failures and making sure it won't happen again, correct? Also, they must find out before Atlantis leaves, right?

Right - normally the reboot is automatic, but that didn't happen this time. This appears to be the first time that the ISS has (had) been without any lanes for a significant period ot time. Sounds like from the commentary this AM that they've recovered one lane overnight, are continuing to troubleshoot, and have asked shuttle to preserve some power to preserve the option of staying an additional day. Russian controllers last night were speculating the problem related to how the power from the new arrays was being routed to ISS - guess something akin to spoiled milk. Managers continued to express optimism that it would all get worked out, but they had to admit the option - however slim at this point - that if they couldn't get it figured out, abandoning the ISS was an option on the table.

So the DMS-R hardware is causing the problems?
Afaik, DMS-R consists of the CPC (Control Post Computer) and FTC (Fault Tolerant Computer). Which one is the source of trouble?
