As much as many of us would love to have access to L2 not all of us can afford it. So please enlighten us.

Who knows, since when there were these black and yellow markings on the floor of FSS (Level 195) around the elevator shaft and in front of the EES baskets?

Were there such markings already from the beginning of the shuttle program or not until later missions? Were there such markings on the RSS too?

What are they doing in the short term (today is 3/30/14) with 39A that is causing the visitor center to stop offering the "up close" tour of the pad?
Without getting into any L2 content I can tell you the KSC Visitor Center guides would tell you that the tours would end once SpaceX formally took possession of the pad.

Anyone know the length of the IAA structure (red line) and the length and width off the GH2 vent line haunch (blue and orange lines)?

And there you have it.

It's also public knowledge that MLP-2 is sitting at 39A. That's going to have go somewhere. Can't stay there forever!

Some insight into why the upclose VAB tours were shutdown.  (L1 content)

What is the diameter of the ET vent line? Based on photos it seems to be around 20-23" in diameter, is this about correct?

According to an old Apollo image I have of the hydrogen facility, the fill/drain line is 10" in diameter with the facility vent line being 18" in diameter. The MLP vent line seems to be about the same as the facility vent line.

At it's largest the ET vent line is 20". Most of the cross-country portion is 18". The MLP vent line varies between 14-16". The facility vent is 12". The fill line outer diameter is 10", but it has a vacuum jacket. The inner line is 8" I believe

A follow up to this Q&A: What is the outer diameter of the aft flexhose of the GH2 vent line? Another GH2 vent line Q is how was the Vent Line Handling Fixture on the IAA attached to the vent line when it was in the retracted position?

I have been trying to locate drawings of the Apollo LUT and MLP.  As well as the swingarms.  I have found a few, but they are usually just basic diagrams.

Does anyone know the distance between the FSS SE column and the RSS hinge column?

I believe it is 24 ft 0½ inches center-to-center.

Thanks. I had some trouble reading the number listed in the LC-39B FSS/RSS Demolition Package document.

I now have reason to believe the 24 ft 0½ inches measurement note in the LC-39B FSS/RSS Demolition Package document is in error. I just can't get the RSS to fit over the orbiter properly with that measurement.

It makes the PCR cover too much of the orbiter in the Z axis. After some experimentation, the real center-to-center distance is more like 28.57 ft.

Well, in in all fairness, it is marked "VERIFY".

After some further research, the center-to-center distance of the SW column of FSS and the RSS hinge column is 35 ft, according to the LC-39A Recordation document which has this:

Quote
The FSS has approximate overall dimensions of 75' in length (north-south),
40' in width, and 350' in height, which includes the tower, the trussing that connects the tower to
the RSS hinge column, and the lightning mast.

Knowing that the basic FSS is 40' square we can remove those 40' from the stated 75' length which leaves 35' for the FSS/RSS trussing.

Hi all,

is there  anyone, who has NASA drawings or dimensions of the ROFIs (Radially Outward Firing Ignitors) of the TSMs?
