SpaceX resurrects California Starship factory plan just one year after abandoning it

Just nine months after scrapping temporary Starship facilities built at a Los Angeles port, the company has unexpectedly reconsidered that decision, restarting talks to build a steel Starship factory in California.

In March 2018, nearly two years ago, the public first became aware of SpaceX’s plans to build a Starship factory in Port of Los Angeles. Begun while Starship was still known as BFR (Big Falcon Rocket) and designed to be built almost entirely out of carbon-fiber composites, the company’s first in-house effort to build its next-generation rocket began in an unassuming tent erected on port property around December 2017. Unintentionally foreshadowing the future of both Tesla Model 3 and SpaceX Starship production, that temporary tent was completed in just a month or two and officially began supporting BFR prototype production in April 2018.

In December 2018, CEO Elon Musk rebranded BFR as Starship and revealed that SpaceX would take the extraordinary step of redesigning the fully-reusable rocket to use stainless steel instead of carbon fiber. One year after SpaceX began building carbon fiber hardware, Musk moved quickly to make the radical move to steel permanent, literally scrapping its BFR prototype tent and abandoning its lease of a separate facility that was meant to host a more permanent composite Mars rocket factory in the near future. Now, almost exactly a year canceling its Port of LA factory, SpaceX has returned with plans to build and finish new port-based Starship production facilities just a few months from now.

Completed in September 2018, the closest SpaceX ever got to producing its 2017 BFR iteration was a large ring-like composite structure, also known as a barrel section. Measuring some 9m (30 ft) wide and 4-6m (12-20 ft) long, both 2016, 2017, and 2018 variants of SpaceX’s next-generation fully-reusable rocket would have been assembled from a number of similar components — all to be built out of carbon composites with giant mandrels (a bit like inverse molds).

While it’s more than likely that SpaceX could have managed the feat, building a reusable orbital spacecraft like Starship out of carbon fiber posed a vast array of challenges. When Musk revealed that SpaceX would move from carbon fiber to steel in December 2018, the CEO went into some detail to explain several of those challenges and why the major change was thus worth the substantial body of work it would force the company to scrap and redo from scratch.

The two biggest hurdles for BFR were quite simple. From a technical perspective, carbon fiber is dramatically less temperature-resistant than most metals (especially steel), meaning that despite it offering a much higher strength-to-weight ratio on paper, almost every inch of the spaceship and booster’s exposed surfaces would have to be insulated. For Starship, this would be exceptionally challenging given that the spacecraft must fundamentally be able to survive numerous orbital-velocity reentries with little to no refurbishment in between. While a steel Starship would still need a proper heat shield on its windward half, the other half of its steel hull could likely be almost entirely unshielded thanks to the fact that most steels remain structural sound at much higher temperatures.

Beyond the “delightfully counterintuitive” technical properties that could make a steel Starship as light or even lighter than the carbon composite alternative, Musk also noted that a huge motivator for the switch was the fact that the cutting-edge composites SpaceX would have to buy were incredibly expensive. In September 2019, Musk stated that composites would have cost some $130,000 per ton, whereas a ton of the stainless steel SpaceX is now using can be purchased for just $2500. In simpler terms, from a material cost perspective, steel Starships and Super Heavy boosters could cost an incredible 50 times less than their carbon composite twins.

Port Factory 2.0

For now, it’s unclear exactly what SpaceX foresees for Starship’s newly re-proposed Port of LA factory. The same primary constraint remains: there is still no affordable way to ship full-scale 9m-diameter Starship hardware by road. The most likely explanation for the resurrected interest in port facilities is that SpaceX still wants to keep some major aspects of Starship manufacturing within reach of California’s vast aerospace talent pool, as well as the company’s own California headquarters, situated just 20 or so miles from Port of LA.

Before SpaceX vacated its prospective BFR factory at Port of LA Berth 240, it had performed a small amount of earthmoving and foundation work. (Pauline Acalin – November 2018)

At the same time, SpaceX probably has all the space it could possibly want at its Hawthorne, CA headquarters after a massive Triumph facility was recently vacated, meaning that any intentional expansion in Port of LA is probably motivated by the need to transport massive rocket parts from California to Texas and Florida. Daily Breeze also reports that “SpaceX would manufacture its…Starship spacecraft and…Super Heavy [booster] on the property” if it receives approval, seemingly implying interest in full-scale rocket production at its prospective port factory.

Regardless of whether SpaceX wants to build smaller Starship subcomponents (i.e. nose cones, header tanks, fins, plumbing, crew compartments, etc.) or complete spaceships and boosters, the company is seemingly far more eager to get port facilities in place, this time around. Specifically, SpaceX told a city council member that it wanted to get a Port of LA facility up and running just 90 days after it expressed new interest in the concept.

At SpaceX’s Boca Chica, Texas outpost, the company has used Sprung Structures to add 100,000+ square feet of enclosed factory space in just a month or two. (NASASpaceflight – bocachicagal)

To do so, SpaceX will copy the methods used to create both Tesla’s General Assembly 4 factory addition and its own massive Starship production space in South Texas, relying on Sprung Instant Structures to erect a massive semi-permanent tent or two in an extremely short period of time. Unfortunately, because of how abruptly SpaceX abandoned its Port of LA factory lease, the company will have to repeat the permitting and environmental review process from scratch, making it very unlikely that it will be able to begin construction within the next month or two.

Regardless, SpaceX certainly remains as agile as ever. Stay tuned for updates on this surprise resurgence of plans for a Port of LA Starship factory.

Tesla adds new feature that will be great for crowded parking situations

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.

Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.

Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.

However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.

It also reveals the distance you are from your car, which is a big plus.

Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.

Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’

Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”

Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.

Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.

While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.

Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.

The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”

This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.

Jeff Dean, the Chief Scientist for Google DeepMind, said on X:

“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”

Musk replied:

“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.

Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.

According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.

The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.

The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.

Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.

Tesla teases new AI5 chip that will revolutionize self-driving

AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.

Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.
