Ship 29 is the newest oddity at the Production Site, but we may know what's happening this time around. Let's take a look at this new article that SpaceX is producing, and why we believe it may be a Structural Test Article. (1/13)
@ChameleonCir Starting off looking at S29's nosecone, we can see some TPS pins on the side. This is likely because S29 was intended to be a normal Ship. With the cone now outside of the tent and having other work done, the pins will likely not be finished. (2/13)
@ChameleonCir@nomadd13 Well then, it's probably just another S26, right? That was a possibility until SpaceX began properly developing the flap mounting surfaces. This typically happens after tiling, and if this nose has no tiles, it would burn up before needing flaps. (3/13)
@ChameleonCir@nomadd13@RGVaerialphotos A nosecone test article would need these mounting points though, because flap simulators are installed for the structural testing. (4/13)
@ChameleonCir@nomadd13@RGVaerialphotos@BocaChicaGal If this is for a test article, we expect that the tip of the nosecone would be removed, similar to what happened to SN12's nosecone nearly two years ago. This is yet to happen, but we anticipate that it will soon enough. (5/13)
@ChameleonCir@nomadd13@RGVaerialphotos@BocaChicaGal Now, let's move down to the Payload Bay. It had a fairly normal trip through the production process until SpaceX installed only a stripped-down base portion of the dispenser. (6/13)
@ChameleonCir@nomadd13@RGVaerialphotos@BocaChicaGal@NicAnsuini This piece did not have the expected electrical parts and systems that a working PEZ dispenser has. Typically a PEZ dispenser is installed as one unit, with all of the hardware preinstalled. (7/13)
@ChameleonCir@nomadd13@RGVaerialphotos@BocaChicaGal@NicAnsuini@StarshipGazer@chrisk_91 All of this suggests that S29 may be an article used to verify the design of Starship's upper half during flight, like what was done with SN12’s nosecone last year. Hopefully, we'll get to see this put together soon and, more importantly, pass testing. (13/13)
As SpaceX prepares to structurally qualify its new interstage design, intended to be used for hot staging, let’s look at the new parts that will be used for this, and what we can learn from these new parts. (1/12)
The test article at the Massey’s testing site is labelled the “Hot Stage Load Head”, and will be used to qualify the interstage against the aerodynamic forces it will experience during flight. There are 3 main components to this. (2/12)

The bottom barrel section is the old Booster 11 forward dome section that was reassigned to become a test article for this, seemingly back in January of this year, possibly suggesting when this design decision was made. (3/12)
Ship 24.2. A confusing test article with a confusing name that has had a confusing life thus far. Today we’re going to talk about how SpaceX is planning to structurally verify the Starship Payload Bay, and why this monstrosity exists. (1/16)

Ship 24.2 will be a 7-ring tall article composed of 3 main sections: a top ring with a dome and 24 external attachment points, a Ship Payload Bay that features a PEZ dispenser rack, and a bottom ring with a hatch in the side. (2/16)

Knowing that this is a 7-ring tall test article, we were able to quickly determine that the newly reconfigured nosecone cage is the perfect height to support this. We’ll come back to this later. (3/16)
With this new photo from Elon Musk, there’s been a lot of discussion about what exactly we’re seeing. Today’s quick thread is going to go a bit deeper into what we can learn from this photo. (1/10)
For starters, let’s figure out the positioning of things. The Quick Disconnect is located in the upper right of the photo, and aft flaps can be identified from the frames the motors sit in. This means that the tiled side is on the lower left of this photo. (2/10)

We can immediately see the Hydraulic Power Unit that powers Ship 25’s Thrust Vector Control in the lower left of this image. Ship 25 is the last Starship to use this, as B9+ and S26+ use an electric TVC system. (3/10)
Some interesting developments have been happening lately with Starship 28, with one of the major ones being the removal of its sliding Payload Bay door. Let’s take a closer look at how this was done, and what it could mean. (1/6)
On June 15th, crews attached a crane to Ship 28’s sliding door, and after somehow reorienting it inside of the vehicle, slid it out. We’ve included an animation of how it was removed if it’s hard to tell from the recording. (2/6)
This is simply the sliding panel that we all see from the outside of the Ship. On Ship 28, you can see that it’s now missing, and what is likely related to the actuation mechanism can be seen hanging in the doorway. (3/6)
Ship 25 has had quite a life so far, and it hasn’t even had its first static fire. Let’s take a look at why this Starship has been so confusing, why many thought it was retired, and how it’s different from Ship 24. (1/13)
@RGVaerialphotos Ship 25 was fully stacked in the Highbay on September 12th, 2022, and was moved to the Launch Complex for cryogenic testing on October 19th. It conducted 3 cryo tests, before being moved back to the Highbay to receive its engines. (2/13)
@RGVaerialphotos@NASASpaceflight@LabPadre In the Highbay, all 6 engines were installed on Ship 25, and the PEZ Dispenser slot on the front was welded closed. Ship 25’s engines still use hydraulically-powered TVC, which changes to electric on Ship 26. (3/13)
One of the major changes on Booster 10 is the beginning of the transition to using SpaceX’s new, flatter smooth domes. While the transition to using these smooth domes hasn’t been as smooth as many hoped, let’s take a closer look at this Super Heavy. (1/6)

@CosmicalChief August 18th, 2022 saw one of these new domes lifted onto the sleeving stand, and it was sleeved by a Booster common dome sleeve shortly thereafter. The common dome separates the CH4 and LOX tanks inside of the vehicle. (2/6)
🎥 @CosmicalChief @NicAnsuini
@CosmicalChief @NicAnsuini Prior to this change, the common dome looked like one of the normal older style domes, just with a hole in it for the massive CH4 transfer tube to pass through. (3/6)
