MD - Hubble will be replaced by JWST before needing a 2010+ extension.

One question. Why did they even bother to remove the ISS docking adapter on Atlantis? Were they that tight on weight for STS-125? Would be pretty handy right now if Atlantis could unload the HST-SM4 payload and then load up with the STS-126 MPLM.
The ODS was removed to support STS-125 EVA activities. Furthermore, it takes a good deal of time to configure the Shuttles' payload bays for mission specific cargo. Atlantis' PLB is configured for the SM-4 payload. It would take months to reconfigure it for the STS-126 payload -- much longer than simply letting Endeavour fly the mission she's configured for in November.

Yeah, I figured it wasn't that simple. Almost as if it were rocket science. 
They can still do EVA's with the ODS installed, can't they? I figured they removed it for weight or CG issues. Am I wrong?
Could be wrong, but I thought it had to do with EV crewmember clearance issues with the Super Lightweight Interchangeable Carrier in the PLB.

Not to mention that STS-126 needs the SSPTS, which Atlantis doesn't have.

HI , Question for you all.
So is it 100% not possible for a 2008 launch of Atlantis to HST?
Has the date for STS-126 been changed at all? If I cant see STS-125 I am hoping to try to plan for STS-126..
Also have the LTT Tickets for STS-126 gone on sale yet? Thank You very much.

LTT tickets aren't relevant to processing (use the viewing thread for that to keep things on track), but it's 95 percent certain that STS-125 is no go for 2008.
STS-126 is being planned for a move to Pad 39A for a November 14 (NET) launch.
All still in the planning stages and memos etc. are going into L2. I will collate key info into articles as we get a solid idea of status.

Bill - when do you formally decide 126 is up next? Would it make more sense to launch 119 before 125 due to beta cutouts?
John - 126 decision point, removing payload, putting in canister, rolling 125 stack to HB3, then moving 126 from Pad A to Pad B... If they got go tomorrow, they could launch Nov 2. But crew training or cargo delivery would not support that day - so they have 12 days to make decision and still make Nov 14th. Next Friday make decision.
This seems like the most likely outcome, except 126 would go from (current) pad B to pad A where Atlantis is now, correct?

Why can't STS-126 be launched from pad B?

Because the B PCR cannot support payloads. They used items from the B PGHM to get the A PGHM up to date. Also the B PCR isn't up to cleanroom standards anymore.

Does anyone know if Hubble went through a diagnostics exercise/testing process that caused side A SIC&DH to malfunction or is it purely coincidental that it failed just weeks before the service mission?

There's a HST engineer conducting a Q&A on L2 and he mentioned it happened, or was spotted, during a self-check, but there's no pinpoint to the point of failure yet. They've pulled in one of the original HST guys to help.

Yes, but I figure that this self-check has been performed regularly through out Hubble’s 18 years in service. Nothing suggests that this self-check were performed only because of the then up coming STS-125 mission.

The HST engineer has confirmed on L2 that the self-test that caused the safe-mode is running continuously. So in other words it probably was purely coincidental.

The self-test didn't cause the safe mode... The self-test failed, which put most of the instruments into safe mode.
