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

Dome to barrel weld made it to 7.1 bar, which is pretty good as ~6 bar is needed for orbital flight. With more precise parts & better welding conditions, we should reach ~8.5 bar, which is the 1.4 factor of safety needed for crewed flight.— Buff Mage (@elonmusk) January 10, 2020
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.
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.
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 ramps production of its ‘new’ models at Giga Texas
The vehicles are being built at Tesla Gigafactory Texas in Austin, and there are plenty of units being built at the factory, based on a recent flyover by drone operator and plant observer Joe Tegtmeyer.
Tesla is ramping up production of its ‘new’ Model Y Standard at Gigafactory Texas just over a week after it first announced the vehicle on October 7.
Earlier this month, Tesla launched the Tesla Model 3 and Model Y “Standard,” their release of what it calls its affordable models. They are priced under $40,000, and although there was some noise surrounding the skepticism that they’re actually “affordable,” it appears things have been moving in the right direction.
The vehicles are being built at Tesla Gigafactory Texas in Austin, and there are plenty of units being built at the factory, based on a recent flyover by drone operator and plant observer Joe Tegtmeyer:
News: the @Tesla Model Y Standard production is well underway at Giga Texas today!
This consistent with what I was told to expect during the unveiling day last week!
The outbound lot had many Premium Model Y’s and @cybertruck too!
More coming soon! pic.twitter.com/WU489QKPLB

The new Standard Tesla models are technically the company’s response to losing the $7,500 EV tax credit, which significantly impacts any company manufacturing electric vehicles.
However, it seems the loss of the credit is impacting others much more than it is Tesla.
As General Motors and Ford are scaling back their EV efforts because it is beginning to hurt their checkbooks, Tesla is moving forward with its roadmap to catalyze annual growth from a delivery perspective. While GM, Ford, and Stellantis are all known for their vehicles, Tesla is known for its prowess as a car company, an AI company, and a Robotics entity.
Elon Musk was right all along about Tesla’s rivals and EV subsidies
Tesla should have other vehicles coming in the next few years, especially as the Cybercab is evidently moving along with its preliminary processes, like crash testing and overall operational assessment.
It has been spotted at the Fremont Factory several times over the past couple of weeks, hinting that the vehicle could begin production sometime next year.
Tesla could be greatly impacted in one of its strongest markets as the government is ready to eliminate a main subsidy for electric vehicles over the next two years.
In Norway, EV concentrations are among the strongest in the world, with over 98 percent of all new cars sold in September being electric powertrains. This has been a long-standing trend in the Nordic region, as countries like Iceland and Sweden are also highly inclined to buy EVs.
However, the Norwegian government is ready to abandon a subsidy program it has in place, as it has effectively achieved what it set out to do: turn consumers to sustainability.
This week, Norway’s Finance Minister, Jens Stoltenberg, said it is time to consider phasing out the benefits that are given to those consumers who choose to buy an EV.
Stoltenberg said this week (via Reuters):
“We have had a goal that all new passenger cars should be electric by 2025, and … we can say that the goal has been achieved. Therefore, the time is ripe to phase out the benefits.”
EV subsidies in Norway include reduced value-added tax (VAT) on cheaper models, lower road and toll fees, and even free parking in some areas.
The government also launched programs that would reduce taxes for companies and fleets. Individuals are also exempt from the annual circulation tax and fuel-related taxes.
In 2026, changes will already be made. Norway will lower its EV tax exemption to any vehicle priced at over 300,000 crowns ($29,789.40), down from the current 500,000, which equates to about $49,500.
This would eliminate each of the Tesla Model Y’s trim levels from tax exemption status. In 2027, the VAT exemptions will be completely removed. Not a single EV on the market will be able to help owners escape from tax-exempt status.
There is some pushback on the potential loss of subsidies and benefits, and some groups believe that the loss of the programs will regress the progress EVs have made.
Christina Bu, head of the Norwegian EV Association, said:
“I worry that sudden and major changes will make more people choose fossil-fuel cars again, and I think everyone agrees that we don’t want to go back there.”
With the loss of the $7,500 Electric Vehicle Tax Credit, it looks as if Tesla CEO Elon Musk was right all along.
As the tax credit’s loss starts to take effect, car companies that have long relied on the $7,500 credit to create sales for themselves are starting to adjust their strategies for sales and their overall transition to electrification.
On Tuesday, General Motors announced it would include a $1.6 billion charge in its upcoming quarterly earnings results from its EV investments.
Ford said in late September that it expects demand for its EVs to be cut in half. Stellantis is abandoning its plan to have only EVs being produced in Europe by 2030, and Chrysler, a brand under the Stellantis umbrella, is bailing on lofty EV sales targets here in the U.S.
How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies
The tax credit and EV subsidies have achieved what many of us believed they were doing: masking car companies from the truth about their EV demand. Simply put, their products are not priced attractively enough for what they offer, and there is no true advantage to buying EVs developed by legacy companies.
These tax credits have helped companies simply compete with Tesla, nothing more and nothing less. Without them, their products likely would not have done as well as they have. That’s why these companies are now suddenly backtracking.
It’s something Elon Musk has said all along.
Back in January, during the Q4 and Full Year 2024 Earnings Call, Musk said:
“I think it would be devastating for our competitors and for Tesla slightly. But, long term, it probably actually helps Tesla, that would be my guess.”
In July of last year, Musk said on X:
“Take away all the subsidies. It will only help Tesla.”
Take away the subsidies. It will only help Tesla.
Also, remove subsidies from all industries!

Over the past few years, Tesla has started to lose its market share in the U.S., mostly because more companies have entered the EV manufacturing market and more models are being offered.
Nobody has been able to make a sizeable dent in what Tesla has done, and although its market share has gotten smaller, it still holds nearly half of all EV sales in the U.S.
Tesla’s EV Market Share in the U.S. By Year
-
- 2020 – 79%
- 2021 – 72%
- 2022 – 62%
- 2023 – 55%
- 2024 – 49%
As others are adjusting to what they believe will be tempered demand for their EVs, Tesla has just reported its strongest quarter in company history, with just shy of half a million deliveries.
Will Tesla thrive without the EV tax credit? Five reasons why they might
Although Tesla benefited from the EV tax credit, particularly last quarter, some believe it will have a small impact since it has been lost. The company has many other focuses, with its main priority appearing to be autonomy and AI.
One thing is for sure: Musk was right.
