Anyone know the clocking of the holddown posts on the SRB Aft Skirt in relation to the Booster Z axis?

With regards to the above, is the clocking the same for the SLS boosters?

(Working on an RSRM model right now)

Were there potential Shuttle crewmembers that refused to fly on proposed Shuttle-Centaur missions (Galileo, Ulysses, Magellan)?

Flights of the ‘Death Star’

Quote
In early January 1986, [STS-61F commander Fred] Hauck recalled, "we were working an issue to do with redundancy in the helium actuation system for the liquid oxygen [and] liquid hydrogen dump valves and it was clear that the [Shuttle management] was willing to compromise on the margins in the propulsive force being provided by the pressurised helium. We were very concerned about it."

(STS-61F was to launch Ulysses.)

Quote
"We had discussions about it with the technical people, but we went to a [review] board to argue why this was not a good idea to compromise on this feature. The board turned down the request. I went back to the crew office and said to my crew, in essence, 'NASA is doing business differently from the way it has in the past. Safety is being compromised and, if any of you want to take yourself off this flight, I will support you.'"

Two Shuttles, Two Launches, One Planet…and a Five-Day Goal
By Ben Evans, May 17, 2012

John Fabian was announced as a member of the STS-61G (Galileo launch) crew in May 1985, and resigned from the mission a few months later.  (He resigned from NASA, effective January 1, 1986.)

Quote
One of the reasons for Fabian’s departure was his conviction that NASA prized commercial respectability above operational flight safety. He spent enough time with the 61G crew to see a technician clambering onto the Centaur with an untethered wrench in his back pocket and another smoothing out a weld, then accidentally scarring the booster’s thin skin with a tool. In Fabian’s mind, it was bad enough that the Shuttle was carrying a volatile booster with limited redundancy, without adding new worries about poor quality control oversight and a lax attitude towards safety.

Considering his post-NASA career, according to his NASA bio, last updated in December 1993, Fabian proceeded to
Quote
become Director of Space, Deputy Chief of Staff, Plans and Operations, Headquarters USAF.

Colonel Fabian retired from the USAF in June 1987 and joined Analytic Services Inc (ANSER), a non-profit aerospace professional services firm in Arlington, Virginia, where he is now President and Chief Executive Officer.

Which mobile launcher umbilical towers became the fixed service structures at 39A and 39B? I know ML-1's umbilical tower was scrapped, but I don't know which pads ML-2 and 3's umbilical towers went to.

Thanks for the help!

None? The fixed service structures have been there since the start of the Shuttle program, they're part of the pad not the MLPs

The Fixed Service Structures were created by disassembling the old Saturn V LUTs and trucking them, segment-by-segment to the pads. Pad A's FSS was created from the LUT on ML-2 and the FSS on Pad B was the ML-1 LUT. ML-3's LUT went into the "LUT Bone Yard" in the KSC Industrial Area after it had been removed from ML-3 in order to convert ML-3 into MLP-3 for the shuttle program.

Only the Rotating Service Structures were new builds.

Wasn't ML-1 renamed MLP-3 since it was the last to be reconfigured for Shuttle? I thought I read ML-1 became MLP-3 and ML-3 became MLP-1, with ML-2 becoming MLP-2.

So, would it be:

ML-1 (MLP-3): LUT disassembled, scrapped in 2004
ML-2 (MLP-2): LUT became 39A FSS
ML-3 (MLP-1): LUT became 39B FSS

Is that right?

Yes, that is correct.

Shuttle MLP-1 was formerly Apollo ML-3, and Shuttle MLP-3 was Apollo ML-1. ML-1 was the last ML converted for the Shuttles because it was used for Skylab crew launches, and the ASTP. In fact, MLP-3 wasn't used for Shuttle launches until 1990.
