Big chunk of the RSS came down sometime in the last 48ish hours. Not much of it left at this point :)

That RSS must be totally gone by NOW. (?)

I don't think it will ever be totally gone, just smaller with the crew access arm mounted on it.

The RSS was way too short for that.

Note you're confusing the Fixed Service Structure (FSS) with the (nearly removed) Rotating Service Structure (RSS).

FSS will have CAA.  RSS will be completely removed.
Alphabet soup, anyone?

Good pictures Rocketlover.

Yea, it's almost all gone!
That was SpaceX's plan from the start, as I understood.
I thought they were also planning to add a few new levels to the Fixed Service Structure (FSS) and a crane on top for crew dragon access arm and  for being able to vertically integrate payloads for USAF/DoD missions that require it.

Is that still the plan?  That was from awhile ago.  It looks like the FSS is tall enough they could almost put a crew access arm on that top level and have it reach Dragon ok?

Yeah, the RSS will go, not sure if they still plan to add on the the FSS, also, these are not my pictures, just to make sure you know, I found them on the Facebook group.

The recent NASA Advisory Council HEO meeting had an update on Commercial Crew which specifically called out adding levels to the FSS.

So in these pictures the large crane is obviously working on the RSS. Any recent, yesterday or today photos of the pad? RSS must be gone by now.

On way back on the bus from the Pad 39A, there is 2 story high of steel structural covered with canvas, surrounded by steelworkers and welding tools to the west of Launch Pad 39 Observation Gantry. Since the host bus said no camera shooting is allowed from inside the bus, no photos was taken of this structure.

This structure seems to have the same dimensions as FSS's so maybe this is the one that will be dismantle in sections and transport to the top of FSS?

247 ft + ~40 ft (20 ft level height x 2 levels previously mentioned) = 287 ft.

High enough for a VI crane + Category 3 fairing?

Is the other crawler still parked there? Might be that.

Wow! That is very much gone. It is going to be interesting to see how/if they remove the hinge portion. Surely they will, but that alone will be an incredibly heavy piece to remove unless done in segments.

It has been speculated that the hinge is structural and will remain by someone who was familiar with the original construction on this site, IIRC.  Sorry I don't have a reference for that.

In the simulations released by spacex of the finished 39a the hinge is left in place.

Yes that's where the crawler is usually parked there but this time, the canvas covered structure is perfect box shape like, more like approx 30' high by 40' x 40', too small to be mistaken for much wider crawler.

Correction: Was informed that it's just a big weight/mass simulator taken from VAB and covered by scaffolding for refurbishing.

By the way, whatever happened to the old hammer head crane on top of the tower (carried over from Saturn to Shuttle)?

Stupid question:

what does RSS mean? What was it's purpose on the shuttle/saturn times?

Rotating Service Structure--allowed for "clean room" payload operations at the pad for loading the payload in to shuttles.  Also provided protection to the shuttle orbiter while at the pad.

EDIT:  no question is stupid, though sometimes I challenge that...

Speaking of that FH Animation..Curious if they still intend to cover the FSS in that metal grating type covering?
