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.

Tesla’s little-known secret about its Diner might be the best feature of all
Tesla is not letting its servers go untipped, it’s taking care of that for its employees on its own.
Tesla’s Supercharger Diner in Los Angeles has a little-known secret, and in all honesty, it might be the best part of the entire thing.
Tesla opened its Supercharger Diner earlier in June, and in its first week of operation, it has done nothing but garner attention from fans, food critics, and general onlookers who are surprised to see the company gaining traction in the culinary space.

However, there is a little-known secret about the Diner that many people have not shared, and it has to do with the staff and customers.
Traditionally, restaurants in the United States do not pay their servers a normal wage. They are paid a lower hourly rate because they make most of their money through tips or gratuity. While it is sort of strange and has recently become a more controversial topic, tipping culture in the U.S. has garnered plenty of attention lately.
Many people outside the U.S. have trouble grasping the idea of tipping servers, as many believe the restaurant should pay them a livable wage and stop relying on customers to keep the employees to a point where they can live reasonably well.
In the U.S., people seem to be on board with one side or the other: tip them because the restaurant doesn’t pay them a wage, or “I’m not tipping them for doing their jobs.”
Whichever side of the argument you’re on, I think it seems reasonable to want servers to make enough money to live comfortably and expect the restaurant to take care of that.
Tesla has done just that for the staff at the Supercharger Diner, as it has been revealed that the company covers tipping. There is no option to tip the servers or wait staff; Tesla will do it for you.

This is a great gesture by Tesla because more and more people every day seem to be against tipping in an effort to force restaurants to pay employees more money. While it seems like a good strategy at first, it only impacts the servers, while this decision does not impact the restaurant and its owners.
Tesla is taking that risk out of the equation by providing gratuity to employees through its own means.

xAI, Musk Foundation helps schools near Memphis supercomputer site
Reports of xAI and the Musk Foundation’s work were recently posted by local news media.
Elon Musk’s artificial intelligence startup xAI and the Musk Foundation have been supporting Memphis-Shelby County Schools with HVAC repairs and facility upgrades, while also funding youth programs for students in the area.
Reports of xAI and the Musk Foundation’s work were recently posted by local news media.
xAI’s school visits lead to facility repairs
Representatives from xAI visited John P. Freeman Optional School, Fairley High School, and Westwood High School, all of which are located near its Colossus supercomputer site, to assess HVAC systems, plumbing, gym facilities, and athletic fields. The visits resulted in a list of priority repairs, some of which were completed in April and May.
In addition to the repairs, xAI also shared a number of initiatives that are planned for students in the area, as stated in a Commercial Appeal report.
“xAI is working on providing STEM workshops for local students, donating equipment to technical training programs, and supporting job fairs to boost employment opportunities. These initiatives reflect xAl’s commitment to fostering education and economic growth in Memphis,” xAI noted in a statement.
Musk Foundation donation
Apart from xAI, the Musk Foundation also donated $350,000 to the Boys & Girls Clubs of Greater Memphis, enabling the reopening of two club sites located at Booker T. Washington High School and Westwood High School. Both locations had closed earlier this year due to lapses in funding. As per xAI, the Musk Foundation’s donation allows clubs to reopen for almost 1,000 students.
The donation will fund staffing, supplies, and transportation, among others. “Kids are the future of humanity,” Elon Musk said in a statement, adding that students need “every chance to shoot for the stars.”
“We’re honored to support the Boys & Girls Clubs of Greater Memphis in reopening these sites, giving kids in underserved communities the tools to build brighter futures,” Musk said.
The gift was praised by local officials, including Boys & Girls Clubs board chair Michael Garriga, who stated that the “commitment will ensure the youth of our community have the opportunities they need to develop their skills and talents to become successful students and future citizens.”

What to expect from Tesla CEO Elon Musk’s new Master Plan
While Musk only shared a few tidbits about his next plan, he did hint at its theme.
Tesla CEO Elon Musk is working on another Master Plan. The executive mentioned this during the company’s second quarter earnings call earlier this week. While Musk only shared a few tidbits about his next plan, he did hint at its theme.
Master Plan Part Four
Elon Musk’s Master Plans have been a huge guiding hand for Tesla over the past couple of decades. His first Master Plan, which was published in 2006, featured a pathway towards the production of the Model 3 and energy storage systems. Master Plan, Part Deux, which was published ten years later in 2016, featured a pathway towards a Robotaxi network.
Master Plan Part 3 was more ambitious, as it presented a case towards a world where there is sustainable energy for the entire planet. Considering the scale and ambitious nature of Master Plan Part 3, it was widely speculated that Elon Musk’s next Master Plan would not be around for some time. During the second quarter earnings call, however, Musk confirmed that he is indeed creating his next big plan.
Master Plan Part 4
Elon Musk mentioned his next Master Plan when a question was asked about the work that goes on inside the Tesla Design Studio during the Q2 2025 earnings call. In response to the inquiry, Tesla Chief Designer Franz von Holzhausen emphasized that while earnings calls are not the venue for disclosing new product-related information, Tesla is working to ensure that the future remains exciting. Musk agreed, stating that there are lots of exciting things happening in the Tesla Design Studio.
“What’s going to happen over the next several years is a fundamental transformation of the company from a pre-autonomy world to a post-autonomy. And I’m working on a new Master Plan to articulate that to the Tesla team. And there will be some teething pains as you transition from a pre- autonomy to post-autonomy world, but I think the future vision for Tesla is incredibly exciting and will profoundly change the world in a good way,” Musk said.
A Post-Autonomy World
Considering Musk’s comments, it would appear that Master Plan Part 4 will be focused on a path towards what the CEO has been describing as “sustainable abundance.” If Master Plan Part 3 was focused on fostering sustainable energy for the entire planet, Master Plan Part 4 will likely present a path towards abundance in a world populated by self-driving vehicles like the Cybercab and humanoid robots like Optimus.
Master Plan Part 4 will likely have been farfetched just a couple years ago. Yet with Tesla now operating its Robotaxi service in Austin and Optimus V3 expected to enter production next year, the idea of a world filled with “sustainable abundance” does seem quite feasible. It will be ambitious like Elon Musk’s other Master Plans, of course, but it will be attainable.
