SpaceX Starship factory overflowing with new and flight-proven rockets
After a relatively relaxed period of production and testing, SpaceX’s South Texas Starship factory is practically overflowing with new and flight-proven ships as the company prepares for the rocket’s next major tests.
Even before the one-off Starship Mk1 prototype failed a pressure test late last year, SpaceX was in the process of upgrading its Boca Chica production facilities and refining the ship’s design and manufacturing processes. Starship SN1, the first prototype built as part of that upgrade, rolled to the launch pad on February 25th, 2020, followed by Starship SN2 (turned into a test tank) just a week or so later. Starship SN3 and SN4 would both follow in early and late April, ultimately ending with the latter prototype’s spectacularly violent demise in late May.
Over the remaining three or so months, the pace of testing has slowed a bit as SpaceX’s Starship development program enters the full-scale flight testing phase. Starship SN5 began testing on July 1st, followed by SN6 around six weeks later. Both prototypes successfully hopped just 30 days apart. Now, although SpaceX still plans to hop SN5 a second time and may hop SN6 twice, too, the Starship program’s focus has shifted to high-altitude, high-velocity flight tests and the adoption of a new steel alloy.
Presumably in anticipation of a learning curve as that new steel alloy begins to be tested at full-scale for the first times, SpaceX is churning out Starship prototypes at an unprecedented pace. Intriguingly, that production ramp is hinged upon the assumption that a 304L-class steel alloy (compared to the 301 stainless steel used to build SN1 through SN6) will be as good or better than 301 steel in every significant way.
Currently, that assumption isn’t entirely baseless but is still built upon the success of Starship SN7, SpaceX’s first 304L test tank. SpaceX never confirmed its results but it’s believed that that test tank – more of a material demonstrator than an actual structural Starship prototype – surpassed all previous pressure records before it burst in June.



Given that SN7 performed quite well, it’s at least a bit less surprising that SpaceX is hinging months of work and at least four full-scale Starship prototypes on an otherwise unproven steel alloy. The next big test for 304L Starships will be a second test tank known as SN7.1. Rolled to the test site on September 7th, essentially as soon as Starship SN6 was safed and returned to the factory after its hop debut, SN7.1 is significantly more complex than its sibling and will test a ~304L Raptor mount (thrust puck) and skirt section. The forces and general conditions those new parts will be subjected to are substantially different than most of what SN7 was subjected to, meaning that there is a chance that 304L steel is less optimal in different scenarios.
With any luck, SN7.1’s test campaign – scheduled to begin as early as 9pm CDT (UTC-5), September 10th (today) – will be a flawless success, proving that SpaceX’s new steel alloy is universally superior to 301 for Starship-related applications. If that’s the case, Starship SN8 – the first full new-alloy prototype – will likely be fully outfitted with a nosecone and header tanks before beginning acceptance testing.


Eventually, if SN7.1 aces its tests and SN8 performs well during preflight preparations, Starship SN8 could become the first prototype to launch with a full nose, header tanks, and flaps, as well as the first to fly with three Raptor engines. If Starship SN8 fails for any reason or is damaged during testing, though, it appears that SpaceX will have no shortage of ships built out of the same new steel alloy to choose from.
In just the last ten days, labeled parts and rings for Starships SN9, SN10, and SN11 have all been spotted, implying that SpaceX is concurrently building at least four new Starships. Notably, both Starships SN9 and SN11 already appear to have some of the studs needed for heat shield tile installation affixed to sections of their steel hulls. Based on the sheer number of steel ring stacks spotted over the last week, it’s also safe to assume that SN9’s tank section (and possibly SN10’s, too) is largely prefabricated.






Assuming two of the in-work nosecones are ultimately meant for flight, SpaceX may already have enough hardware on hand to fully assemble two Starships (presumably SN8 and SN9) – including nosecones, header tanks, nose rings, and flaps. It’s safe to say that if SN7.1 achieves its goals, preparations for the first triple Raptor hop, 20 km (~12 mi) test flight, and skydiver-style landing attempt could come together incredibly quickly.

Taiwan power firm bets big on Tesla Megapacks as AI data center thirst grows
Taiwan’s Apollo Power orders 260 Tesla Megapacks, betting AI data centers will need more electricity.
A Taiwanese power company has ordered 260 Tesla Megapack 2XL units, roughly 1GWh of storage, betting that electricity rather than chips will decide how fast AI data centers come online. Apollo Power signed the contract with Tesla’s Taiwan energy arm on October 8, according to the company’s filing with the Taiwan stock exchange.
The filing says the units are meant for behind the meter storage and resilient grid projects, with delivery in batches from the end of 2027 and sites operating in 2028. Apollo and Tesla did not disclose a price, citing a confidentiality agreement. Apollo plans to pay for the equipment through a cash capital increase and bank financing, and it noted the purchase is not revenue and does not mean it holds firm orders from its partners.
Biggo reported that only about 33 units are under signed customer contracts, with roughly 150 more in negotiation. The same report put total project investment near NT$130 billion, but that figure includes installation work, with the equipment itself making up about 40 to 50 percent. In other words, a large share of this order is Apollo reserving supply ahead of demand. Apollo’s chairman told local media global large storage supply is tight, which is why the company locked in the units early, according to Yahoo Taiwan Finance.
Apollo also launched an AI data center and grid resilience alliance with Phison, Gigabyte and Shihlin Electric. The pitch rests on a pilot at Phison’s Zhunan plant, where Apollo and Tesla Energy Taiwan installed grid forming Megapack 2XLs in June. Tesla Energy Taiwan general manager Sun Hsiao-Han said the project went from demo to 1GWh in four months, and that Tesla Energy has deployed more than 50GWh worldwide.
Taiwan’s cabinet has approved amendments that would require large energy users to install their own generation and storage, which gives enterprise storage a regulatory tailwind.
The deal fits a pattern Teslarati has tracked. Tesla’s Megablock targets 1GWh commissioned in 20 business days, a pitch aimed squarely at fast moving data center builds. Megapacks already back xAI’s Colossus in Memphis and a 400MW AI campus in Brazil. Sun Media adds that Megapack 2XL was named among the first products in Nvidia’s DSX Ready qualification for battery storage in AI factories.
Deliveries are more than a year away, so the real test is how much of that 260 unit order turns into signed customer contracts.

Tesla Cybercab and Robotaxi’s real advantage won’t be the ride service
For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.
Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.
Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.
Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant
Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.
This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?
If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.

Why Elon Musk’s target date for buying an Optimus robot is harder than it sounds
Musk says China’s magnet export ban cost Optimus months, and robot hands remain shockingly hard.
Elon Musk says China’s export curbs on magnets used in electric motors set back Tesla’s Optimus program by two to three months, and that the robot’s hands remain the hardest part of the project. He made the comments Saturday during a live interview with Tesla Owners Silicon Valley at the X Takeover event at Giga Texas, in front of roughly 2,000 attendees. The Optimus discussion begins around the 49 minute mark of the stream.
On the hands, Musk was blunt and noted that a general purpose humanoid needs fine motor skills that are “incredibly difficult to get right. Shockingly difficult,” he said in the interview. He pointed to a problem he says no one has demonstrated yet: “One of the hardest things also generally is to do precision and force at the same time,” such as driving a small self tapping screw into wood. Touch sensors add another layer, since it is “actually kind of hard to get touch sensors that elastically deform and can handle high cycle life and it won’t just break after a few thousand cycles.”
He also took aim at rival robot videos. “Any complicated looking robot demo, it’s a canned demo. It’s not real,” Musk said, adding that real AI means showing a robot something it has never seen and watching it still cope, the way FSD handles a city it has never driven.
Musk expects the Optimus ramp to be slower than a new vehicle production ramp. “The initial part of that S curve of production ramp is going to be very slow at the beginning,” Musk said, partly because “unlike cars, there’s no pre existing supply chain for robot stuff.” That echoes his July reply on X that Optimus production “will be extremely slow at first, as everything is new.”
The magnet disclosure puts a number on a problem Musk first raised in 2025. He said China “prevented the export of magnets for use in electric motors” and that it “set back the Optimus program by like two or three months.” Then he added: “We had robots with no arms.” Tesla’s fix is to bring the supply chain home. “You’ve got to be able to make all the parts domestically,” he said. Teslarati reported in April 2025 that Musk tied the issue to permanent magnets in the arm actuators, where motors have to be as small as possible.
Tesla Optimus V3 hand and arm details revealed in new patents
Production is moving regardless, with a reported internal goal of more than 1,000 a week by the end of 2026. Teslarati recently covered how Tesla is certifying supply partners in China for Optimus parts, while the company’s hand design has been the subject of new patent filings.
Musk has said he wants Optimus available to the public by late 2027, though Tesla has not confirmed that date or published updated production figures.
