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 has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.
Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.
There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.
Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.
Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.
Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.
🚨🚨 Tesla Supercharging had a HUGE year, and they deserve to be recognized.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.
Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.
Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla shocks with latest Robotaxi testing move
Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.
Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.
However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:
🚨 Tesla is using Model S vehicles fitted with LiDAR rigs to validate FSD and Robotaxi, differing from the Model Ys that it uses typically

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.
Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.
Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”
However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.
Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla
Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.
Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.
Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.
CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.
He said:
“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”
At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:
“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”
The Hardware
Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.
It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.
ACM3 specs include:
- 1600 sparse INT8 TOPS (Trillion Operations Per Second).
- The processing power of 5 billion pixels per second.
- RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
- RAP1 is enabled by an in-house developed AI compiler and platform software
As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”
More Details
Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.
More than any other feature, our owners have asked for more hands-free miles.
With Universal Hands-Free, you can now enjoy hands-free assisted driving on any road with clearly defined lanes. That’s roughly 3.5 million miles in the U.S. and Canada.
Look for it in our next… pic.twitter.com/ZFhwVzvt6b
