SpaceX just blew up a Starship tank on purpose and Elon Musk says the results are in

That's probably not gonna buff out. (NASASpaceflight - bocachicagal)

Before dawn on January 10th, SpaceX technicians and engineers intentionally blew up a miniature Starship tank in order to test recently-upgraded manufacturing and assembly methods, likely to be used to build the first Starships bound for flight tests and orbit.

SpaceX CEO Elon Musk quickly weighed in on Twitter later the same day, revealing some crucial details about the Starship tank test and effectively confirming that it was a success. While somewhat unintuitive, this is the second time SpaceX has intentionally destroyed largely completed Starship hardware in order to determine the limits of the company’s current methods of production and assembly.

Most notably, on November 20th, SpaceX is believed to have intentionally overpressurized the Starship Mk1 prototype in a very similar – albeit larger-scale – test, destroying the vehicle and sending its top tank dome flying hundreds of feet into the air. It’s generally believed that SpaceX (or perhaps even just Musk) decided that Starship Mk1 was not fit to fly, leading the company to switch gears and deem the prototype a “manufacturing pathfinder” rather than the first Starship to fly – which Musk had explicitly stated just a few months prior.

Instead, Starship Mk1 suffered irreparable damage during its pressurization test and was rapidly scrapped in the weeks following, although several segments were thankfully salvaged – perhaps for use on future prototypes. Along those lines, it can arguably be said that the results from the mini Starship tank’s Jan. 10 pop test have paved the way for SpaceX to build the first truly flightworthy Starship prototypes – potentially all the way up to the first spaceworthy vehicles.

Hours after the test, Musk revealed that the Starship test tank failed almost exactly where and how SpaceX expected it would, bursting when the weld joining the upper dome and tank wall failed. Critically, the tank reached a maximum sustained pressure of 7.1 bar (103 psi), some 18% over the operating pressure (6 bar/87 psi) Musk says Starship prototypes will need to be declared fully capable of orbital test flights. In other words, given the tank’s size, it survived an incredible ~20,000 metric tons (45 million lbf) of force spread out over its surface area, equivalent to about 20% the weight of an entire US Navy aircraft carrier.

Musk also revealed that SpaceX will require Starships to survive a minimum of 140% of that operating pressure before the company will allow the spacecraft to launch humans.

Some have less than generously taken to smugly noting that several modern spaceflight and engineering standards require that launch vehicle tankage be rated to survive no less than 125% of their operating pressure, while this test tank would be rated for less than 118% under identical conditions. However, this ignores several significant points of interest. First and foremost, the Starship test tank intentionally destroyed on January 10th was assembled from almost nothing – going from first weld to a completed pressurization test – in less than three weeks (20 days).

Second, all visible welding and assembly work was performed outside in the South Texas elements with only a minor degree of protection from the coastal winds and environment. Although some obvious tweaks were made to the specific methods used to assembly the prototype tank, it also appears that most of the welding was done by hand. For the most part, in other words, the methods used to build this improved test article were largely unchanged compared to Starship Mk1, which is believed to have failed around 3-5 bar (40-75 psi).

Additionally, it appears that almost all aspects of this test tank have smaller structural margins, meaning that the tank walls and domes are likely using steel stock that is substantially thinner than what was used on Starship Mk1. Nevertheless, thanks to the addition of continuous (single-weld) steel rings, a tweaked dome layout, and slightly refined welding, this test tank has performed anywhere from 20% to 200+% better than Starship Mk1 – again, all while coming together from scratch in a period of less than three weeks.

SpaceX technicians finished welding the tanks two halves together less than 24 hours before the tank was successfully pressure-tested. (NASASpaceflight – bocachicagal)

As Musk notes, with relatively minor improvements to welding conditions and the manufacturing precision of Starship rings and domes, SpaceX can likely ensure that Starships (and thus Super Heavy boosters) will be able to survive pressures greater than 8.5 bar (125 psi), thus guaranteeing a safety margin of at least 40%. Even a minor improvement of ~6% would give vehicles a safety margin of 125%, enough – in the eyes of engineering standards committees – to reasonably certify Starships for orbital test flights.

Technicians worked through the night and into the predawn morning to prepare the mini Starship tank for an intentional test to failure. (NASASpaceflight – bocachicagal)
Although several hours after a scheduled roadblock, SpaceX ultimately successfully completed the pressure test around 5 am CST (11:00 UTC), January 10th. (NASASpaceflight – bocachicagal)

All things considered, it’s safe to assume that SpaceX is going to begin building and assembling Starship SN01 (formerly Mk3) hardware almost immediately. Given that this test tank took just 20 days to assemble, it’s safe to say that the upgraded prototype’s tank section could be completed in just a handful of weeks. Stay tuned for progress reports.

Tesla warns consumers of huge, time-sensitive change coming soon

Tesla is urging customers to take delivery of their new EV by September 30 in order to take advantage of the $7,500 tax credit.

Tesla is continuing to warn consumers of a huge, time-sensitive change that is coming soon, as the end of the EV tax credit is less than two months away.

The EV tax credit has offered $7,500 off new EVs and $4,000 off used EVs for certain individuals who qualify due to income. For years, it has been a great incentive for consumers, and it has improved further as car companies were able to apply the credit at the point of sale starting in 2023.

Tesla is ready with a perfect counter to the end of US EV tax credits

However, with the Trump Administration, it always seemed as if the EV tax credit was in jeopardy. Earlier this year, the White House officially announced that it would do away with it completely.

On September 30, the tax credit will be abolished. In order to utilize it, customers will have to take delivery of their vehicle by that date. Orders placed before September 30 without delivery by that day will not be able to utilize the credit.

Tesla is truly pushing this point incredibly hard: the sooner an order gets in, the more likely you are to take delivery of the car by September 30.

The end of the EV tax credit is something that has been looming on the minds of electric carmakers, consumers, and investors.

The $7,500 discount for buying a clean energy vehicle truly puts many of the cars in a much more affordable price range. Without it, the least expensive Tesla model will be the Model 3 Rear-Wheel-Drive, which starts at $42,490.

That price comes down to $34,990 with the tax credit, and brings the monthly payment down about $130, depending on how much money is put down.

Despite the change, CEO Elon Musk does not believe it will impact Tesla negatively. In fact, he has been in favor of getting rid of the EV tax credit for several years, believing it will actually work to Tesla’s advantage.

Perhaps the most interesting thing that will come of this is how all EV makers will be impacted by the loss of credit. Musk believes Tesla will come out as the big winner here, especially as it plans to roll out new affordable models sometime this year.

Tesla is not releasing Unsupervised FSD to regular customers yet, but the company seems to be preparing something special for its FSD users nonetheless. 

This was, at least, according to Elon Musk in a recent post on X.

Tesla FSD V14

Tesla’s FSD program has been deemed by Elon Musk as one of the key factors that would determine the company’s long term success. Over the past months, however, Tesla has mostly been focusing on the rollout and ramp of its Robotaxi program in Austin and the Bay Area. Tesla’s Robotaxi service uses Unsupervised FSD, which is not yet released to customers.

However, in a post on X, Musk stated that Tesla is preparing its next big update for its consumer-grade FSD system—V14. Musk did not provide a lot of details about FSD V14’s capabilities, but the CEO did state that the update will feature a 10X higher parameter count, among other improvements.

“The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less,” Musk wrote in his post.

Tesla Unsupervised FSD Rollout

During the second quarter earnings call, Tesla executives were asked for a timeline on the rollout of Unsupervised FSD to consumer vehicles. In his reply, Musk stated that he believes Unsupervised FSD will be available for consumers in certain geographies. He did explain that Tesla will be extra careful with the system’s release. 

“We are getting there. I think it will be available for unsupervised personal use by the end of this year in certain geographies. We are just being very careful about it. This is not something we should rush,” Musk said, adding that “I am confident that by this year, within a number of cities in the US, it will be available to end users.

Elon Musk has reaffirmed the Tesla Semi’s mass production date. He mentioned the update in a post on social media platform X during the weekend.

Tesla Semi Factory

The Tesla Semi was initially unveiled in late 2017, and its first deliveries were held in December 2022. Since then, Tesla has only been delivering the Semi to a handful of customers while it builds a dedicated factory for the Class 8 all-electric truck near its Giga Nevada facility.

Drone flyovers of the Tesla Semi factory over the past months have suggested that progress in the construction of the facility has been steady. More recent flyovers have even suggested that Tesla is now busy outfitting the facility with the necessary equipment for the mass production of the Semi.

Elon Musk’s Recent Comments

In a recent comment on X, Elon Musk reiterated the idea that the Semi was indeed expected to be mass produced in 2026. Musk shared his update as a response to a Tesla bull who recalled that Bill Gates did not believe that the Semi was feasible due to the limitations of battery technology. In his response, Musk posted a laughing emoji together with “Tesla Semi will be in volume production next year.” 

The Tesla Semi factory near Giga Nevada is expected to be capable of producing 50,000 units of the Class 8 all-electric truck per year. While this number may not be attained by the facility right out of the gate, it would only be a matter of time before the factory manages to hit an optimal production rate.

In a video posted on social media earlier this year, Dan Priestley, who leads the Semi program at Tesla stated that the company is preparing for volume production over the coming quarters. With such a pace, the factory should be able to mass produce the Semi in 2026.
