Did anyone notice what appeared to be a jet of gas under the external tank in the DOAMS replay?
I saw it, though it looked more like water vapor dropping from the aft of the tank than a jet.

Anyone see the giant ice chunk stuck to the left SSME that burned off at Main Engine Start
As for the vapor, thats all it appears to have been. Not sure about the SRB gimbaling but it does not appeard to have affected the flight, if it happened.

Good burn concluded a few minutes ago. Crew working block 3 on the Post Insertion list and finishing up on the Ascent checklist.
This concludes with a mode changes to OPS 106.

Yes I'm sure whatever it was took an expanding jet appearance due the aero forces acting on it at those high speeds. I'm just surprised there would be enough water to form that feature for as long a duration as it did. Can anyone pull a screenshot? It was from the Patrick DOAMS.

That was odd. In that last view the SRB nozzles appeared to be gimbling like crazy for a while after the roll. But it was hard to tell if it was real or just atmospheric distortion or camera shake.
Okay, just saw this same thing from another angle. From that one, it looked more like the recirculation plume just dancing around a bit more than I've seen in the past.
Agreed. Normal dancing flame as far as my eyes can tell at first glance. In any case the SSME's were not doing any excessive gimballing.

Appears to have been some liberation just after OMS ignition. Looks like it missed thought

MCC advising that the GPC configuration will be a 'Single G2' setup.
This means only one GPC computer running the flight software, another will be configured to run the SM software with the remaining three shutdown.

Thoughts on potential liberation after OMS ignition (after SRB sep)?

Into block 1 of the PI checklist. First up one of the GPCs will be 'Freeze Dried' to store the guidance software.

Yup, thanks for the screenshots. Should be switching back to KSC for the post-launch presser pretty soon.

No problem and someone else can feel free to take the presser. I don't type fast enough for those!

Burn will be around 1:03 in duration and delta V is in the 135 fps region.
I would think 135 fps is a bit high. That would be right for a 2 OMS burn for a 180k lbs weight orbiter (2.14 fps/s), but I'll bet it weighs more
than that. So I'm guessing closer to 97 fps (for 250k lbs).
Cheers for beautiful launch!
