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

None? The fixed service structures have been there since the start of the Shuttle program, they're part of the pad not the MLPs
Quote from: brickmack on 07/11/2018 06:44 pmNone? The fixed service structures have been there since the start of the Shuttle program, they're part of the pad not the MLPsThe 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.

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 2004ML-2 (MLP-2): LUT became 39A FSSML-3 (MLP-1): LUT became 39B FSSIs that right?Thanks for the help!
What "triggers" the Roll Program? MET? Velocity? Altitude?
-Did the SRB's ignite at T + 3 seconds? I can hear a voice in the nasa feed counting up, "T+1, T+2, T+3".
-When chase is counting down the number of feet to TD where is that altitude coming from? Radar on the chase?
"Roll Program" - What is the crew looking for to cue them to say "Roll Program" and "Roll Program Complete"?What "triggers" the Roll Program? MET? Velocity? Altitude? STS-1 -Pre launch I thought I heard the phrase, "up arrow, down arrow"?-Did the SRB's ignite at T + 3 seconds? I can hear a voice in the nasa feed counting up, "T+1, T+2, T+3".-What is being called down by the crew at approx. 1:04:00 in the video feed. It is shortly after, "Go at 40". Sounded to me like, "434 max q 48"
