SpaceX nails first Starship landing weeks after NASA Moon lander contract [updated]

Published

Update: For the first time ever, SpaceX has successfully landed a Starship prototype in one piece and kept the giant steel rocket intact throughout the post-flight safing process. The fun, however, is just beginning.

First and foremost, excluding simpler Starship prototypes SN5 and SN6, Starship SN15 is the first prototype to actually complete that safing process. In theory, safing a liquid fuel rocket is a fairly novel task given so few rockets are actually reusable. It involves detanking, purging plumbing and Raptor engines, deactivating explosive flight termination system (FTS) charges, and more generally verifying the health and status of all systems. With a rocket as complex as Starship, SpaceX is treading new ground with almost every step, meaning that even something as seemingly benign as keeping a rocket intact after a successful landing carries risk (e.g. SN10).

SN5 and SN6 also had a rough go of things even after surviving their landings and it took anywhere from 12 to 24+ hours before SpaceX declared either vehicle safe to approach. The degree to which Starship SN15’s launch and landing was a success is hinted at by the fact that SpaceX had teams approaching the rocket less than four hours after touchdown. Still, more than six hours after landing, those SpaceX teams were still working to transport a crane to the site after rolling a self-propelled modular transporter (SPMT) within the vicinity of Starship SN15.

Eventually, that crane will lift SN15 onto a custom jig installed on said SPMT and take its flimsy, unreliable legs out of the equation. At that point, the Starship prototype will well and truly be safe and secure and ready for whatever else SpaceX may have in store, be that a quiet future as a permanent display or the program’s first reuse. Stay tuned for updates as SpaceX secures the historic rocket and prepares to reopen the highway to the public.

In perhaps the best possible news that could have followed NASA’s historic SpaceX Moon lander contract, the company has successfully landed a Starship prototype in one piece – without it exploding – for the first time ever.

In spite of unusually unreliable live views from the rocket’s onboard cameras, possible due to SpaceX using Starlink as a Starship antenna for the first time, Starship serial number 15 (SN15) touched down at the very edge of the landing pad a bit less than seven minutes after lifting off from SpaceX’s Boca Chica launch facilities.

Like all four of its predecessors, Starship SN15 ignited all three of its Raptor engines and gradually ascended to an altitude of ~10 km (6.2 mi), shutting down one engine every 90 or so seconds along the way. At apogee, after briefly hovering under the power of one engine, the last Raptor cut off and Starship angled over onto its belly and simply fell back to Earth.

Using four large steel ‘flaps,’ the rocket controlled its descent like a skydiver down to approximately 500m (~2000 ft) above the ground and ignited two or three of its Raptors to aggressively flip into a tail-down orientation. SN15 then slowed all the way down under the thrust of two of those engines for an exceptionally soft – albeit inaccurate – landing on a concrete pad.

Much like SN10, which caught on fire shortly before touchdown, landed intact, and then exploded after that fire continued to burn, Starship SN15 appeared to catch fire shortly after landing and a significant fire burned for at least five minutes before disappearing. As a result, be it intentional on behalf of SpaceX or simple luck, SN15 did not explode after touchdown. The Starship also landed far more gently than Starship SN10, which effectively pancaked its tiny legs and embedded its skirt directly into concrete.

Ultimately, Starship SN15’s fully successful launch and landing is an immense achievement after four failed – but data-rich – attempts and confirms that SpaceX is on the right track. Perhaps even more importantly, the success is quite possibly the best conceivable vindication for NASA after the space agency made the shocking decision to return humanity to the Moon with SpaceX’s Starship.

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 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:

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.
