Those "holes" are the usual ones for the fairing conditioning. The umbilicals were connected to the second stage. On the "moon shot" of Falcon 9 on the pad you can see the new hardware and on the strongback there's an extra QD going to the top of the second stage, this is the QD for methane and oxygen for this lander.

And for those curious, T0 to the second was 1:05:37AM EST (06:05:37 UTC) for this launch.

With this hindsight, the most easily observable confirmation is the gradual addition and outfitting of boxes/plumbing (presumably all the valves, sensors, and controllers needed for methalox loading) on opposite sides of the 39A T/E for several months preceding IM-1. The cutouts are visible by Oct 2023 (Psyche), followed by the appearance of two new partially plumbed control boxes around the end of 2023 (USSF-52), and finally both fully-installed boxes with insulated plumbing by Jan/Feb 2024 (Ax-3/IM-1).

Regarding the mission update, note that any posts unrelated to the launch itself should now go in the IM-1 mission thread.

I notice that the F9 second stage is still close to the Nova-C, do we know if the stage will be left on this trajectory, and if so what will happen to it? I'm guessing it will swing past the Moon and end up orbitin the Sun out of the way?

If it flies by the Moon, it will be on the inbound side of an elliptical orbit that has an apogee beyond the Moon.  Not sure what happens then.  The Moon won't be there when it is ascending toward apogee.

Celestrak data at https://celestrak.org/NORAD/elements/table.php?INTDES=2024-030 now shows the two objects (IM-1 and Falcon stage 2) have markedly different apogees. Is it reasonable to conclude the second stage performed a third MVac burn to accomplish this?

Likely not a burn, but a blowdown of tank residuals through the MVac nozzle as part of its inerting process.

As per Bill Harwood's usual practice, if launch is on the :00 second, it is truncated.

IM-1 is on its way to be the first American spacecraft to land on the lunar surface since the Apollo program ended more than 50 years ago!

Another good choice would be the Blue Danube waltz (a la "2001" - the scenes when Heywood Floyd is heading towards the moon).

Thanks Ed, and to the others who posted info. It seems that the second stage will have vented it's tanks to become inert, which along with the Nova-C burn will have separated the two vehicles. I suspect the stage will eventually re-enter the Earth’s atmosphere, but I'll keep a look out for updates.
