SpaceX CEO Elon Musk & Raptor engine make surprise visit to Florida Starship
While on the East Coast for Falcon Heavy’s third launch, also described as SpaceX’s most difficult launch yet, CEO Elon Musk dropped by the company’s Florida Starship campus and recorded a small acceptance speech for his 2019 Stephen Hawking Medal.
On the very same day, at the very same site, a lone Raptor was effectively displayed for all to see to such an extent that unaffiliated photographers were able to capture impressively detailed photos. Almost the certainly the first time a full-scale Raptor has traveled east of Texas, the engine’s presence at SpaceX’s Florida Starship site is truly surprising in light of the fact that the East Coast campus is solely focused on building orbital-class prototypes. Why, then, is one of SpaceX’s small handful of completed Raptors in Florida?
About a month ago, Elon Musk was announced as the recipient of 2019’s Stephen Hawking Medal of Science Communication. Meant to be awarded in person at a ceremony in Switzerland, Musk was unable to attend the event due to a schedule conflict with Falcon Heavy’s third launch, but the infamously busy CEO managed to film a brief thank you message that was then broadcast in Switzerland.
In what seems to be a coincidence, Musk’s message – either recorded or streamed – was filmed on SpaceX’s Florida Starship development campus, a surprisingly large facility uncovered less than two months ago. The CEO was standing in the sun directly in front of two large segments of the second orbital-class Starship prototype, part of a parallel development process featuring a second Starship prototype (and separate Starhopper) in Texas. Musk’s appearance at Starship Florida is not particularly surprising; if he flew all the way to Florida for Falcon Heavy, might as well tour SpaceX’s newest Florida facilities on the same trip.
Raptor Mystery: Episode II
What is surprising, however, is the presence of what looks like a finished Raptor engine in Florida. Looks can certainly be deceiving but SpaceX’s Florida Starship prototype – while undeniably flying through preliminary assembly – does not appear to be anywhere near flight-readiness. In Boca Chica, a partially separate SpaceX team is working to prepare Starhopper – a partial-fidelity, suborbital prototype – for low-altitude, low-velocity hop tests
Back in May, a mystery Raptor engine – believed to be serial number 04 (SN04 – appeared in South Texas and was soon installed on Starhopper for fit-checks and tests of the engine’s thrust vectoring capabilities. SN04 was soon uninstalled and shipped elsewhere; perhaps to SpaceX’s rapidly-progressing Florida Starship. If the surprise Florida Raptor is, in fact, SN04, then it’s safe to assume that it will remain inert for the time being, serving as a fit-check article and opportunity for training and familiarizing technicians and build engineers. At the moment, Florida’s Starship lies in several large segments, including what appears to be the early stages of its first propellant tank bulkhead(s).
Nevertheless, as partially demonstrated above, SpaceX’s Florida team is wasting no time at all. By all appearances, they are rapidly catching up with Texas, at least as long as Boca Chica’s Starhopper work is excluded. Given the benefit of the doubt, SpaceX Texas would likely be at a similar stage of Starship develop after a similar amount of time (~2-3 months), but much of the Boca Chica workforce has been focused intently on building, upgrading, and testing Starhopper, essentially a flying testbed for Raptor and BFR development.
To an extent, Florida’s orbital Starship prototype looks even more refined than its relatively rugged Texas cousin. Given an additional 1-2 months of nonstop work and a rate of progress similar to the last two months, it’s not out of the question that the Florida prototype will begin to seriously resemble a finished Starship. By all realistic accounts, some of the most difficult work will be found inside and around Starship’s finished aeroshell, though, and the process of outfitting avionics, plumbing the propellant/propulsion sections, and implementing hydraulic/actuation systems will be a huge amount of work.
Even after Starship East is effectively complete, SpaceX will still face the seemingly immense challenge of transporting a massive spacecraft that weighs several dozen tons and measures 9m (30 ft) in diameter and 60m (200 ft) tall from Cocoa to Pad 39A, a full 20-30 miles of public roads and highways. In fact, the easiest method of transporting may involve getting Starship onto a barge in the nearby Indian River and towing it 100+ miles by water to the beach adjacent to Pad 39A. Regardless, neither method is going to be quick or easy and both will put on quite a show for local observers.

Tesla released Full Self-Driving version 14.3.6 last week, and after what was potentially one of the best FSD releases in v14.3.5, there has been a bit of a regression. While there are some bright spots, the changes made to v14.3.6 seem to have backtracked some behaviors.
Overall, it is hard to really complain about FSD in any sense; it has revolutionized how I travel literally anywhere. According to my self-driving app, the last time I went a day without using it was 59 days ago.
However, I think it’s also important to recognize when things are just plain bad with FSD. There are times it does truly mind-boggling things, and I’ll dive into those here. Additionally, I only had these issues on local roads, not on highways. Highway operation, generally, is always incredible other than the occasional complaint about speed or left lane camping.
With those things being said, my personal experience may not represent others’ experiences. A handful of people have said they have had a similar experience on v14.3.6, while others have said it is more than normal.
Turning Hesitancy, Inaccuracy
I’ve noticed more inaccuracy turning into multi-lane stretches of road than in any version I can remember. I’ve had at least three instances of FSD turning into a stretch of roadway that has two or more lanes, and not selecting a lane confidently as it has in past versions.
I think Tesla FSD v14.3.6 is a regression from previous .3 branches
This version in particular has been incredibly hesitant, jerky, and indecisive at times. There’s actually been two drives that I have decided to not used FSD for the remainder of the trip. These were local trips… pic.twitter.com/YobHDOKRS6

Instead, the car will drive over one of the dashed road lines, and the steering wheel will jerk back and forth before picking the lane. It should be said that it has always picked the correct lane when choosing based on the navigation, but it is still very indecisive. The steering wheel jerking is reminiscent of some of the later versions of v13.
I admit I really hate to see the steering wheel jerking come back. However, I think when Tesla releases v14.3.7, it won’t be present. When there are occurrences of it in FSD versions, it is usually resolved by the following release.
FSD Disregards Manual Turn Signals
This is my biggest bone to pick with FSD other than Navigation issues, but this one seems like it would be such an easy fix.
If Tesla is going to put the word “Supervised” on the end of “Full Self-Driving,” then when I tell the car to do something, it should do it. If I input an increase in speed by pressing the accelerator, the car will immediately respond. It does not disregard my input because it feels it is traveling at the right speed.
FSD should never disobey and turn off turn signals that the driver inputs. Trying to direct the car into the correct lane, I had initiated the left turn signal not once, not twice, but three times, with the car turning it off all three times and continuing in a lane that would end in just one block. The only solution at this point would be to zipper merge.
This goes back to the fact that self-driving’s biggest bottleneck might be rider preference. A zipper merge might have been more than reasonable, might have saved me time that I spent sitting through an additional light cycle, and might be something many drivers would do. I was in no hurry, I traditionally do not try to zipper merge because it feels inconsiderate, and lastly, the car should have just followed my input.
This caused me to disengage and drive manually the rest of the way home. Sometimes I just do not need FSD to try to pass every car it can at intersections.
Bird Braking is a Thing of the Past
The big complaint with recent versions of Full Self-Driving has been what we’ve coined as “bird braking,” which is when the car will brake suddenly as a bird flies past.
There have been zero issues with this so far in v14.3.6, which is an excellent improvement.
FSD Might Already Be Taking Note of Driver Preferences
Another thing I have noticed over the past few days is that v14.3.6 seems to already be taking my preferences with navigation into account.
This is something that is supposed to be rolling out with the Summer Update, but I have a hunch it’s already present and might have been included in this v14.3.6 build. On Friday, FSD pulled into an entrance to a local convenience store that it had never attempted to go into before.
Typically, I manually pull into this entrance because it avoids heavy cross traffic at the main entrance. FSD has always chosen that congested main entrance.
I don’t want to get anyone excited but my Tesla running FSD v14.3.6 just:
✅ Pulled into an entrance at my local Sheetz that I routinely pull into manually but FSD never has entered
✅ Pulled into my assigned parking space at home despite many other spots being vacant https://t.co/ZUShvknTWO pic.twitter.com/83O5a2S0eh

Additionally, FSD has pulled into my assigned parking spot at my townhouse community on multiple occasions with this release. This is something that used to happen ocassionally, but not consistently.
It also navigated back to the same convenience store last night, drove through crazy cars scrambling to gas pumps, navigated out of the parking lot correctly, drove me home, and, once again, parked in my assigned spot.
As previously stated, this release just seems to have a few things that need to be brought to Tesla’s attention, and also to make others who use FSD aware of some things that I’ve experienced. I look forward to the next release that will remedy these issues, just as Tesla has always done in the past.
Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.
“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.
The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.
In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.
However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.
Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.
The sheer scale of TERAFAB is going to be insane.
Elon said it wouldn’t be suitable for anywhere on Giga Texas property because it’s too big:
“We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.
“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”
He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”
SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.
Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.
All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.
Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:
This flight intentionally had much higher acceleration to test how well the heat shield tiles would remain attached at high dynamic pressure.
Test was successful.
— Elon Musk (@elonmusk) July 25, 2026
SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.
Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.
The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.
