Oh that's pretty.

Also, a Raptor has been removed from SN8 for some reason (sorry for small image, I screenshotted it from the LabPadre stream)

I wonder if they are removing two of the Raptors to do a static fire test fed from the LOX header tank, once the nose cone is attached. If something goes wrong they don't want to lose all three Raptors.

Or they may even remove all three Raptors just to pressure-test the header tank, for the same reason.

If they were smart they would have a way to get inside the white nosecone, and build in floors (whatever material that would support people), then stage it to look like some sort of interior to get a sense of the available volume.

Excellent observation. I bet you are right.

Who's to say they won't?

Possible. We'll just have to see what they do.

It looked to me like they did a pressure test on the nosecone header tank this morning alongside the RCS tests, as we saw what was definitely venting. It makes sense, they wouldn't want to install the nosecone only to find that the header tank doesn't hold pressure.

Ah, good point. Yeah, so it's more likely they only remove 2 engines and leave the third if they want to do a header-flow static fire.

I just thought about this - wouldn't they want to keep all 3 Raptors if they were doing a header tank static fire? Wouldn't they want to see how the plumbing handles 3 engines drawing propellant at once?

My guess is that the plumbing from the header tank flows into a common entry point in the thrust puck plumbing along with the plumbing from the main tank, so testing one tests all of them.

However they may keep all three Raptors if they want to test the flow capabilities of the header tank.

For all I know they're just swapping this Raptor out for a different one for other reasons.

Yeah, I guess. Looking at the LabPadre feed, we saw an engine come out and get lowered out of view, then another Raptor (or possibly the same one and they just removed it for inspection) went in a while later. I'm not sure why.

This could be one of those ultimately historic days that’ll never be remembered... the last sunset without a complete Starship in the world. :cool:

Yeah, I hope so, unless it RUDs

Beautiful.

Even the airliner part? Wow.

Anyway, I can't help but cringe at that forced "mission control" pseudo-pun.
