Quite a long TFR until Feb 28th

Altitude: From the surface up to and including 1800 feet MSL

https://tfr.faa.gov/save_pages/detail_0_0024.html

This is not a new TFR; it is a continuation of the usual low-level TFR that has been over the area for many months now.

Can’t quote user Chopsticks because previous thread is locked, but yes, the new nosecones are shinier then the SN9,8,...iterations. SN8 always looked like a lead-tipped bullet with its dull nose. I actually grew to like the look. The new iterations of nose (starting with SN10 I believe) look to be more like the same type of stainless as the rest of the vehicle.

Yes. SN10's nosecone is shiny apart from one piece which is still dull. Easy to spot which piece.

Can't never could.   ;)

Back to the actual prototypes, there's been a little something I've been wondering. Maybe I'm seeing things, but do the latest nosecones look shinier or different? Perhaps it's just me, but it seems like a few months ago they were more of a matte grey and looked kind of dirty or maybe unpolished. Some of the latest nosecones showing up over the past couple of months though seem to have the same look that the rest of the rocket has. SN9 looks pretty uniform, but if you check back to July or so, the cones then didn't look as nice. Just an observation on my part that I don't remember seeing discussed.

SN9, if I err not, is the first SN to be completely 304 stainless. I don't know if this means the nosecone as well or if it's just the tank section. But I'm curious what changed. Do we know for sure what kind of steel is being used for the nosecones or are we assuming it's the same thing they use for the the tanks?

Also, it's interesting that if SN9 is 100% 304L (including the nosecone) and presumably SN10 is as well, why they look different. Maybe I'm overanalyzing it and all they did is do some polishing.

Remember, they knocked out a bunch of nose cones several months back. As long as they continue to fit the newer bases and there haven't been any major internal changes that obsolete the existing cones, it stands to reason that any *recent* lessons-learned in welding techniques or materials will be "behind" when comparing nose cones to rocket bodies.

They scrapped most of those nosecones, though.

Yes they did, per Elon "They were pointer than needed" or something to that effect.

The current ones are equally pointy (shaped to minimize drag forces going up).  What was scrapped were presumably noses intended for the SNs lost in pressure tests, with the new shape (presumably made blunter for increased cargo volume) generally expected as part of the large set of changes due with SN15.

actually a tanker of LN2 is only about $4000-$5000 if you order enough on contract
And.....just how many of those tanker trucks are needed to fill up SN9 *ONCE*?

From last tweet of RGV. Do you think this is new type of parts for future build of nosecones without horizontal sections? (edit: and less pointy ;) )

That's not the MK1 cone is it? It was shiny and kind of wrinkly looking as this one is. Also, is that a thrust in the upper part of the picture?

Edit: Yes, it definitely is a thrust puck - the updated version

Yes that is Mk1's nosecone to the right of the bay.
And yes there's a starship thrust puck above the Mk1 nosecone. It's a new design.

Zoom on the part (s?) on the rack I was talking about.

Looks to be double curved

Is this a section for a nose cone assembled out of vertical pieces?

Raceway to cover up the pipes and electronics running down the back of the ship?  They’ll need all of that tucked in before they gain significant speed on a launch.

On a different topic - those expecting an early test of SN9 - remember that at least for now, there’s nowhere for them to land it.  It’ll be a while.

Finally, with SN10 looking stacked and ready for roll out soon (just engines to mount?  Have they solved the issue with mounting SN9’s yet?), is the launch mount fixed yet?  I imagine SN9 ended up on the secondary mount because the primary was getting an upgrade instead of a patch up job from the concrete blasting incident.

Big dent has appeared above lox access hole.

Errr... is this bad?

I do not think it is "new" - combination of angle/lighting and typical "surface irregularities"

In combination with vertical robotic welder it really starts looking like that! I´m expecting see soon some new tooling and tall nose cone gantry from tent number 3, moved into low-bay (or similarly tall gantry crane).

Compare to an earlier photo with close-to-identical lighting:

This happened several times to SN8 while it was on the pad in about the same location, and at about the same time of day (don't know if it was ever posted about here, but we freaked out about it in the LabPadre chat when we saw it appear for the first time).

It always popped back out after a few hours and never seemed to be a concern to the SpaceX workers on site.
