SpaceX has moved its newest finished Starship straight from its Boca Chica, Texas factory to a nearby ‘rocket garden,’ all but guaranteeing an early retirement.

Built as the first of several planned backups to Starship SN15, which debuted a number of significant upgrades in April and May, it appears that Starship serial number 16 (SN16) has been retired to a display stand after its only sibling became the first full-size prototype to successfully survive a launch and landing on May 5th. SN16 actually reached its full height before SN15 lifted off and was more or less complete by May 10th. Since then, the prototype has remaining more or less untouched, seemingly waiting for SpaceX to decide its fate in lieu of Starship SN15’s major success.

Ultimately, with SN16 now sitting side by side with SN15 at what will likely become a sort of open-air SpaceX museum, it appears that the company has made up its mind.

Once SN15 touched down, safed itself, and remained standing after a near-flawless 10 km (6.2 mi) test flight, questions about Starship SN16’s fate almost immediately arose. From the outside looking in, replicating that spectacular success was judged a logical next step by many in light of the four variously unsuccessful Starship launches that closely preceded it. If SpaceX could land SN15 and then successfully recover an entirely separate Starship weeks later, it would all but eliminate the possibility that – much like several different failure modes popped up on SN8 through SN11 – the first total success was a fluke.

Given that SN16 was quite literally completed within days of SN15’s launch and landing, it seemed an almost foregone conclusion that SN16 would fly. For a few weeks, it even looked possible that SpaceX would attempt to reuse Starship SN15. However, SpaceX appeared to decide against reuse and rolled its first flight-proven full-size Starship from the pad to a plot of land expected to host a future ‘garden’ for retired SpaceX rockets.

After its three intact flight-proven Raptor engines – valuable in their own right – were removed, Starship SN15 was seemingly retired around May 26th. Three weeks later, SN16 has (quite literally, to an extent) followed in SN15’s footsteps, bowing to an apparently virulent desire within (or at least atop) SpaceX to launch Starship into space and orbit as quickly as possible. From that perspective, assuming enough data was gathered by Starship SN15 to encourage significant confidence that its survival wasn’t an ‘accidental success,’ reusing Starship SN15 or flying Starship SN16 would only really benefit a line of prototypes that had just made itself obsolete.

Much like Starship SN15 debuted “hundreds of improvements” across the board, CEO Elon Musk revealed that Starship SN20 would also involve a “major technology [revision]” to produce the first prototypes with full heat shields, a stage separation mechanism, vacuum-optimized Raptor engines, and more. In fact, that process may still be ongoing, which could explain why SpaceX has yet to begin assembling Starship SN20 – various subsections and components of which have already been completed in Boca Chica.

Confirmed by Musk in March, SpaceX has been working towards a target of no later than July 2021 for Starship’s first orbital test flight. Given that Starship SN20 has yet to enter the assembly phase and that Super Heavy “Booster 2” (BN3) will be the first of its kind and likely need to pass several major tests on its own, July is no longer within reach. Of course, an orbital launch attempt anytime in 2021 would still be a staggering achievement for SpaceX, beating the likes of Vulcan Centaur, New Glenn, and Ariane 6 to the punch despite Starship’s superior performance, unprecedented design challenges, and grander ambitions.

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.

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 hints toward Premium Robotaxi offering with Model S testing

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:

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.

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.
