Ah, fair enough, thanks - any idea which of them is 51L by any chance?

Dennis Jenkins has an excellent table on page 300 of the 1997 edition of "Space Shuttle - The History of Developing the NSTS".
The 25th Space Shuttle flight was STS-33 at KSC and STS-51L elsewhere
The 18th Space Shuttle flight was STS-25 at KSC and STS-51G elsewhere

RS-25D is what they have sitting in a building now at KSC since they've gutted the Orbiter's MPS for SLS. There are something like 15 of them IIRC.
Worth noting that they have not yet started gutting Endeavour's and Atlantis's MPSs.
Also, yes, there are 15 SSMEs sitting at KSC now.

Which are those? I can count only 14 on P&W's chart?

I believe P&W produced a spare SSME (s/n 2062) some time around 2009, which was never intended to be used on the last shuttle missions.

That agrees with my own notes. Last info I had was from a long-term planning document from April 2009 which noted that SSME 2062 was due to be tested Jan 2010. I never heard if the test was completed.

Engine 2062 has never been tested.

There were a lot of skills retention exercises going on towards the end of the program. In other words, if you don't use the skills, you lose the skills. I suspect that building 2062 was one of those exercises.
The parts of ET-139, ET-140 and ET-141 that were made was the result of skills retention. Nearly every project within the program had something of that nature going on.

By the way folks, further to my earlier question about RS-24/25, does anyone know what exactly an RS-24 is? Thanks.

It is for Wikipedia that Colds7ream needs the info so I don't think that's a good source 
Exactly! I can't find any other reference to RS-24 as an SSME designation, so I'm fairly sure its erroneous, wanting to check. :-)

I was watching the STS-39 post-flight presentation video and noticed that a white rod hanging down from the port PLBD. Any idea what it might have been?

What's the long-term plan for archival of all the Shuttle program electronic documentation and software? Is it going to be accessible for FOIA requests, etc. in the future? (For the stuff that isn't ITAR'd, of course.) Is the archival plan different for different centers/projects/offices/contracts, or is there going to be one massive set of tapes labeled "Shuttle" somewhere?

Any shuttle document that fits the definition of a "federal record" will go to the National Archives. It will all be electronic; any paper-only documents will be scanned first.
There was a parallel "knowledge capture" exercise, on an organization-by-organization basis, where key documents were archived locally along with lessons to help educate the workforce on future programs.
Beyond that, what got archived was an organization-by-organization decision. Many organizations are saving the last full backups from internal servers, but that doesn't necessarily mean the data will be easily accessible.
Archiving doesn't change FOIA status; any document that was exempt from FOIA (e.g. due to ITAR or other export-control laws) during the shuttle program will remain exempt.

Hi,
This morning's topic is AHMS!
Is there any reason there is (was?) no shaft-speed sensor on the HPOTP? Did searching the wider frequency-band (as compared to the HPFTP) work out well? {Did it ever workout better? The wider search conceivably could...}
Did the flight version of the AHMS hardware have the two PowerPC chips for the System Control/Linear Engine Model? Or was that only on the ground version?
Will any of the AHMS work (or Phase II stuff that was discussed, such as engine throttling in the face of unexpected vibration) find its way into any current/near-current rockets?
Thanks!

HELP!!
There is either a post launch or post landing news conference in which Mike Moses comments that "it is easy to go high and easy to go fast, it is hard to go high AND fast".
He makes this comment when answering a question about how private industry will look to experienced NASA engineers to solve the commercial human spaceflight puzzle.
Does anyone know which news conference that was. Like I said, it was either a post launch or post landing...I just don't know which and I don't know what mission it was on.
Any help would be GREATLY appreciated!!!!
Thanks!!!
Jeff
