Hi all, I just realised that there isn't an STS-126 thread yet, so I thought I'd start one!

All future news of STS-126 can be posted here.

STS-126 (Endeavour) is scheduled to launch to the ISS on:
(EST) Fri 14 Nov 2008 @ 7.55pm
(GMT/UTC) Sat Nov 15 2008 @ 00.55am
It will carry the Leonardo MPLM to the ISS to deliver equipment to boost the stations capacity to 6 crew.

Endeavour is currently on pad 39B. It will roll around to pad 39A on Oct 25, after being released from its STS-400 duties. The Leonardo MPLM is due to arrive at the pad, ready for loading, on Oct 23.

The MPLM is currently being filled with cargo in the SSPF (Space Station Processing facility).

The operation can be viewed HERE on channels 5, 8 ,10 & 12.

Endeavour has currently had it's RCS fuel loaded at pad 39B.

There is an issue with Endeavour's External Tank. When it was being assembled in the Michoud facility in Louisiana, technicians reported hearing a "clanging" noise coming from inside the tank when it was hoisted vertical. Technicians in the VAB at KSC again heard it when it was being hoisted vertical for it's stacking. They believe a bolt or screw is loose inside the tank. It has been deemed not a threat and has been cleared to fly, but worse-case scenario is that this thing could be ingested into the SSME (Space Shuttle Main Engine) and cause the engine to explode!

Thats all I know for now....

Astronauts Suit up for Practice Sessions

Oct. 9, 2008
The crew of STS-126 will don training versions of their pressure suits and take part in training inside a full-scale mock-up of the space shuttle’s crew compartment at NASA’s Johnson Space Center.

In the last week of October, the astronauts will fly to NASA’s Kennedy Space Center in Florida for the countdown dress rehearsal.

The International Space Station is the destination for the crew as they take supplies and equipment to the orbiting laboratory.

AFAIK, Endeavour will perform STS-126 ahead of STS 125 this November. Atlantis will fly STS-125 sometime early next year, and I think that Discovery will act as STS-400 LON for the flight. I'm sure I'll be corrected if I'm wrong.

There is also some pad-switching that is planned to put Endeavour on 39B (or is it A) to launch STS-126 ahead of 125

Yep, STS-126/ISS ULF2 will launch ahead of STS-125/HST SM4 due to the failure of the HST CU/SDF Side A on September 28.

Atlantis will be rollbacked to VAB HB3 on Oct. 20 after which Endeavour will be rolled-around from Pad B to Pad A for final pre-launch ops. STS-126 payload goes to pad A on Oct. 23.

New STS-LON number if they choose to go with Discovery would be STS-401 as STS-400 is specific to Endeavour. Has to do with the Flight Software(FSW).
 
STS-126 will launch as planned in Nov
STS-125 will launch in STS-119's slot in Feb
STS-119 will be slotted into March, in between 125 & 127 in May
 
The Leonardo MPLM has just been loaded into the payload cannister in the SSPF...

The cannister will be taken to Pad 39A tomorrow...

Nope. Payload to pad is on Thursday(Oct. 23). That's what all the KSC integrated schedules shows. Wx could be a factor for Endeavour's rollaround on Saturday however. Current forecast from the 45th Weather Squadron has a 60% chance of rain on Saturday.
 
These technicians will confirm the bolt or something will not be a problem right? Cause aren't these the same technicians that said cold o-rings wouldn't be a problem, or falling foam wouldn't be a problem?
 
Well, they have already said that it is safe & have cleared it for flight, but as you say, they said that about Challenger too....
 
What assurances do they have this bolt won't be ingested? I'm assuming the intake valves for the LH2 and LOX are at the aft (bottom) of their respective tanks ; which is where this bolt is certainly going to wind up too.

How can they know "100%" that there is zero risk regarding it?
 
The payload cannister is heading out of the SSPF now...

So long, Leonardo....:cheers:

This is a tad off-topic here, but what happens to the MPLMs after the shuttle retirement? Will they be left on the station by the last logistics flight? I'd hope so so that way they can continue to serve.
 
No, they will not stay on the station, they will return to Earth.
STS-126 will be the last ever flight of Leonardo, then I assume it will go to a museum or something...
 
The Pad B Rotating Service Structure has now been swung back in anticipation of tommorow's pad transfer of Endeavour from Pad B where it has served as the rescue orbiter for STS-125 to pad A where she will undergo final prelaunch operations for the STS-126/ISS ULF2 mission in mid-November.

First motion is currently targeted for 0800 EDT with a pad A harddown time of 1500 EDT.
 
They don't know that there is 100% zero risk, they just think, based on nothing but what is likely to happen, that it is not a problem...

Read here for more info...

Not based on nothing, but based on a thorough investigation, as outlined in the link you provided. More succinctly, there is a very low probability of a problem occurring and it is will below the baseline risk of just being on the spacecraft (about 1 in 100 risk of LOCV, IIRC). In response to the above comment on the Challenger incident, it depends on who you are talking about when you refer to "they". To quote the Rogers Commision report:
...failures in communication... resulted in a decision to launch 51-L based on incomplete and sometimes misleading information, a conflict between engineering data and management judgments, and a NASA management structure that permitted internal flight safety problems to bypass key Shuttle managers.
I don't think you can say that the same thing is happening here.
