Nine days after becoming the first full-size prototype to survive a high-altitude launch and landing, SpaceX has installed Starship SN15 at the second of two identical launch mounts to prepare for potential reuse.

On May 5th, after a week or two of several minor delays, Starship SN15 – the fifth full-size prototype of its kind – lifted off from SpaceX’s Boca Chica, Texas launch pad under the thrust of three Raptor engines. Like all four of its predecessors, the 50-meter-tall (165 ft) steel rocket easily ascended to an apogee greater than 10 km (6.2 mi), shutting down one Raptor every ~90 seconds to its keep velocity low. When the final engine cut off, SN15 arced over onto its belly and free-fell to around half a kilometer above the ground, using four hollow steel ‘flaps’ to control its orientation like a skydiver’s limbs.

The most radical maneuver came around six minutes after liftoff when the sideways Starship reignited two or three of its Raptors, aggressively flipped into a nose-up position, deployed six stubby landing legs, and gently touched down a few hundred feet east of the stand it took off from.

Despite a fairly large fire that burned for several minutes after touchdown, SpaceX ultimately found itself – for the first time ever – with a full-size Starship prototype that survived its inaugural ~10-km launch and landing. A careful process of safing and securing then followed as operators commanded (or monitored) SN15 to disarm explosive flight termination system (FTS) charges, vent any remaining propellant, and eventually depressurize its fuel and oxygen tanks.

Unlike Starhopper, SN5, and SN6 – which also survived flights – SpaceX was apparently able to safe SN15 without any real issues and recovery teams were able to approach the rocket within a few hours of landing instead of the 12-24+ hours that were normal prior. SpaceX also debuted a sort of supersized version of the ‘Octagrabber’ robots that remotely secure Falcon boosters after drone ship landings, allowing the recovery team to secure Starship SN15 to a stable platform and transporter without a crane.

No longer at risk of toppling over, Starship SN15 then… sat where it landed. Less than two days after touchdown, CEO Elon Musk unexpectedly revealed that SpaceX “might try to refly SN15 soon,” indicating that initial post-flight inspections had revealed that the first flight-proven three-engine Starship was in excellent condition. SN15 would ultimately spend another four days (six total) sitting on a transporter at the landing zone. On May 11th, SpaceX rolled Starship SN15 from its landing spot to “Pad B” – the second of two identical suborbital launch mounts.

Perhaps due to stormy weather and high wind gusts in the area, SN15 once again sat still – this time for another three days. Ultimately, the Starship prototype was rapidly lifted onto Pad B’s launch mount, secured, and detached from the crane in a matter of hours of May 14th – possibly the smoothest pad installation yet. In the two days since then, SpaceX has begun more in-depth inspections that will ultimately determine whether the first flight-proven Starship is truly fit for a second launch.

That process likely wont take more than a few days and even if SN15 isn’t deemed (re)flightworthy, there’s still a very good chance SpaceX will put the Starship through some kind of test(s) before it’s retired. Stay tuned for more details likely to come this week.

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.

Tesla owners in California, Oregon, and Arizona can now use Lemonade Insurance, the firm that recently said it could cover Full Self-Driving miles for “almost free.”

Lemonade, which offered the new service through its app, has three distinct advantages, it says:

  • Direct Connection for no telematics device needed
  • Better customer service
  • Smarter pricing

The company is known for offering unique, fee-based insurance rates through AI, and instead of keeping unclaimed premiums, it offers coverage through a flat free upfront. The leftover funds are donated to charities by its policyholders.

On Thursday, it announced that cars in three states would be able to be connected directly to the car through its smartphone app, enabling easier access to insurance factors through telematics:

Tesla recently was offered “almost free” coverage for Full Self-Driving by Lemonade’s Shai Wininger, President and Co-founder, who said it would be “happy to explore insuring Tesla FSD miles for (almost) free.”

The strategy would be one of the most unique, as it would provide Tesla drivers with stable, accurate, and consistent insurance rates, while also incentivizing owners to utilize Full Self-Driving for their travel miles.

This would make FSD more cost-effective for owners and contribute to the company’s data collection efforts.

Data also backs Tesla Full Self-Driving’s advantages as a safety net for drivers. Recent figures indicate it was nine times less likely to be in an accident compared to the national average, registering an accident every 6.36 million miles. The NHTSA says a crash occurs approximately every 702,000 miles.

Tesla also offers its own in-house insurance program, which is currently offered in twelve states so far. The company is attempting to enter more areas of the U.S., with recent filings indicating the company wants to enter Florida and offer insurance to drivers in that state.
