SpaceX’s Florida Starship hits growth spurt as Texas Starship begins bulkhead installation

In the last week alone, SpaceX’s twin orbital Starship prototypes have made some truly jaw-dropping progress. Onlookers have witnessed Florida’s Starship push through a rapid growth spurt, while the company’s Texas team has begun to install propellant tank bulkheads and work on a triple-Raptor thrust structure.

Meanwhile, SpaceX CEO Elon Musk has suggested that one or both of the orbital-class Starship prototypes could be “almost ready to fly” by August 24th, the date of the CEO’s next official update on Starship (formerly BFR and ITS). Although the actual challenge of building a massive, orbital-class launch vehicle is far subtler than the visible steelwork needed to build its primary structure and pressure vessels, the veritable leaps forward made in both Texas and Florida in the last 7-10 days are extremely encouraging signs.

Bulkheads galore

Starting off in Boca Chica, Texas, SpaceX’s team of engineers and technicians have been simultaneously handling Starhopper’s first untethered flight test (completed on July 25th) and building the facility’s orbital-class Starship prototype. Most significantly, after a few days of preparation, what is likely the Texas Starship’s first bulkhead was lowered inside its ~25m-tall (80 ft) barrel section, composed of the spacecraft’s propulsion section and propellant tanks.

Pictured below, technicians carefully craned the first 9m (30ft) diameter dome inside the Texas Starship on July 30th. Based on its orientation and the recent arrival of a similar dome, this particular bulkhead is almost certainly the bottom dome and first of three to be installed. It will thus serve as the bottom of the Texas Starship’s liquid methane propellant tank, as well as a significant structural member of the rocket’s thrust structure, needed to safely transfer the force of 3-6 Raptors to the rest of Starship.

SpaceX Texas also accepted delivery of the first multi-engine Starship thrust structure, featuring three obvious spots for three Raptors, meshing with Musk’s August 3rd statement that “Starship Mk1” would feature three of the engines.

11 meters, 5 days

Meanwhile, at SpaceX’s similar Florida Starship facility, the similar-but-not-quite-identical spacecraft has experienced even more rapid growth. Over the course of perhaps 4 or 5 days, technicians installed a full six new rings worth of steel segments on the vehicle’s tank section, separated from the curved nose section just like SpaceX’s Texas Starship. With an individual height of almost exactly six feet (~1.8m), the six new rings combined to add more than 10.5m to the Florida Starship’s relative height in just a few days. Combined, the nose and barrel sections would likely reach a height of 45-50m (145-165 ft), roughly 10-15% shy of full height (55m).

No fewer than 7 additional rings are visible in various stages of work (c. Aug. 4) across the Cocoa campus after the recent growth spurt.

Taken on August 4th by local John Winkopp, SpaceX’s Florida Starship campus is buzzing with activity. Just five days ago, the large barrel section was barely 50% as tall. (Seamore Software)

Of note, a bulkhead visible between the Florida Starship’s barrel and nose sections in mid-July disappeared around the third week of the month, a strong indicator that SpaceX’s Florida campus actually beat Texas to their first Starship tank dome installation by as much as ~10 days. The fact that SpaceX is effectively racing itself to build the first flight-ready orbital-class Starship is deeply entertaining, but it also serves as an extremely unique example of the application of A/B testing (commonly used in software dev.) to spacecraft assembly.

Per Musk, the goal is not meant to be cutthroat (i.e. two groups enter, one group leaves) and both groups (Boca Chica and Cocoa) were said to be actively cooperating and sharing important lessons learned. Still, the geographically separated groups are visibly utilizing different methods, facilities, materials, and approaches. In effect, SpaceX has encouraged two of its own groups to duel (albeit in a semi-friendly manner) as a deeply unorthodox method of getting Starship to operational readiness as fast as physically possible.

Although Musk did partially contradict himself on August 3rd, implying that the first orbital Starship prototype(s) could be “almost ready for flight” by late August, the SpaceX CEO stated on July 19th that both Florida and Texas Starships could be ready for their first (suborbital) flights in “2 to 3 months”, or September/October. The first orbital Starship launch would follow as few as 2-3 months after that (or those) first flight milestones.

In short, Musk’s official August 24th Starship presentation is likely to be downright jaw-dropping. Stay tuned!

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.

Tesla Full Self-Driving gets an offer to be insured for ‘almost free’

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.
