Falcon 9 / NROL-108 is rolling out to pad 39A in advance of Thursday's planned 0900 to 1200 ET liftoff. Nice photobomb courtesy of a KSC crawler.

I put this here because it looks like NASA is making room for construction of the second Mobile Launcher.
This might be MLP-1 being moved from maybe the East parking site so that construction can begin.

All IMHO.

I just noticed the multiple slabs of concrete on the deck--a load bearing test?

Again, the next day.
One of the old Space Shuttle MLPs is out and about carrying a whole load of concrete.

26 megapounds  with the ML loaded with concrete atop CT-2.

Max certified lift of flight hardware was 18 megapounds with EM-1 weighing 20 megapounds.  The numbers have changed over the years.  CT-2 got the extra 4 improvements that CT-1 did not.  Shuttles rating was 12 million pounds.

11,800 tonnes with the ML loaded with concrete atop CT-2.

Max certified lift of flight hardware was 8,200 tonnes with EM-1 weighing 9,100 tonnes.  The numbers have changed over the years.  CT-2 got the extra 4 improvements that CT-1 did not.  Shuttles rating was 5,400 tonnes.
As those bizarre units made my head hurt, I've replaced them as a public service. Conversions courtesy of Google, rounded to the nearest 100

Yes, pound are difficult.  Your Metric numbers merely fuddled any comments directed at the article which uses millions of pounds.

That is indeed one of the big issues with the news side of NSF.

The first umbilical – one of many swing arms that will provide power, communications, and propellants to a larger configuration of NASA’s Space Launch System (SLS) rocket – for the agency’s mobile launcher 2 (ML2) arrives at the Launch Equipment Test Facility (LETF) at NASA’s Kennedy Space Center in Florida on Oct. 28, 2021. The umbilical will go through rounds of testing at the LETF to verify it functions properly before getting installed on the ML2 tower. This particular umbilical will provide propellants, environmental control systems, and a variety of purge gasses to the rocket’s Exploration Upper Stage. ML2 will be used to launch SLS Block 1B and Block 2 configurations to the Moon, starting with the Artemis IV mission, allowing NASA to send astronauts and heavy cargo to the lunar surface.

Can't wait to see the fully constructed tower.  The launches from ML-1 may be helpful with ML-2, e.g. beefing up some components, adding blast protection in key areas.

Then there's the problem of what to do with ML-1.  What a tortured history for this structure!  Built, then modified for a handful of flights, then dismantled.  Alas, there is zero chance of keeping the tower as a visitor's display with SLS mock-up.  But nice to think about.

PS:  Some of you may remember a fund-raising campaign years ago to have one of the Saturn V LUTs reconstructed as a KSC visitor's display, complete with a Saturn V mock-up (SA-500F?).  The tower sections were still intact.  I think Boeing actually contributed to that fund.

If you would like to know a little more about ML-2 or its current/future status, Chris Bergin has put together an article with this and other information.

Thanks for article Chris.  Clears up the possible fate of ML-1.

Given that NASA’s Office of Inspector General recently estimated that the cost of the ML-2 launcher has more than doubled, has there been any latest progress in constructing the ML-2 launcher?

Why?  As a monument to waste?
