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 confirms Robotaxi is heading to five new cities in the U.S.

After launching in Austin, Texas, in late June and the Bay Area of California just a few weeks later, Tesla has been attempting to expand its Robotaxi suite to new states and cities in the U.S., and even outside of the country.

Tesla Robotaxi will hit five new cities in the United States in the coming months, the company confirmed.

After launching in Austin, Texas, in late June and the Bay Area of California just a few weeks later, Tesla has been attempting to expand its Robotaxi suite to new states and cities in the U.S., and even outside of the country.

The Robotaxi suite is a ride-hailing service Tesla offers, but the details of it change with each jurisdiction, as regulations vary. For example, in Austin, Tesla can operate the Robotaxi suite without anyone in the driver’s seat, as long as the vehicle does not enter a freeway.

In the Bay Area, a Safety Monitor rides in the driver’s seat, essentially acting as the vehicle operator with Full Self-Driving controlling the car.

The local regulations and how Tesla handles them will continue to be a relevant part of the discussion, especially as the company aims to expand the Robotaxi program to different areas. This has been a primary focus of the company for several months, especially within the United States.

CEO Elon Musk said that Tesla was aiming to launch Robotaxi in Nevada, Arizona, and Florida. However, the company detailed five specific cities where it will launch Robotaxi next during the Annual Shareholder Meeting on Thursday.

Tesla will launch Robotaxi in Las Vegas, Phoenix, Dallas, Houston, and Miami next, broadening its Service Area for the suite to more major cities across the U.S.

It has said it plans to offer the service to half of the U.S. population by the end of the year, but it does not seem as if it will expand to more than a handful of cities this year, which is still tremendous progress, all things considered.

As far as autonomy is concerned, Tesla has always had lofty expectations and has made some even loftier statements.

At the Shareholder Meeting, Musk said that the company would likely be able to enable vehicle owners to text while the vehicle drives, alleviating them from potentially having some of the responsibility they have behind the wheel.

It is not confirmed that Tesla will roll this out in the next few months, but Musk said there is a possibility.

Tesla launches another new Model Y trim at a bargain price with massive range

It is the second most-affordable Model Y trim level in China, trailing the base Rear-Wheel-Drive and coming in under the All-Wheel-Drive.

Tesla has launched yet another new Model Y trim level, but this time it is in China, and it is at a bargain price.

It also has an insane range rating.

On Friday, Tesla launched the new Model Y Long Range Rear-Wheel-Drive in China, priced at 288,500 yuan ($40,500), an incredible deal considering it is not a stripped-down version of the vehicle like the Model Y Standard.

It is the second most-affordable Model Y trim level in China, trailing the base Rear-Wheel-Drive and coming in under the All-Wheel-Drive.

The big appeal with this new Model Y trim is obviously its price, but its range rating is also one of the best we’ve seen. Rated at 821 kilometers on the CLTC scale, it converts to 510 miles. It uses a 78.4 kWh CATL battery.

Converted to real-world range, however, that 821-kilometer range rated by the CLTC actually is equivalent to about 357 miles on the EPA scale, which is still a very respectable number and comes in at a higher range than the Long Range All-Wheel-Drive configuration that is available in the U.S.

Tesla has truly brought a wide variety of Model Y trims to the Chinese market, including a new Model Y L configuration that features a slightly longer wheelbase, as well as additional interior features like extended thigh legrests and captain’s chairs with armrests.

It is unclear whether Tesla will bring a Premium Rear-Wheel-Drive option of the Model Y to the U.S., especially as it has already rolled out four configurations of the all-electric crossover in the market. With the new Standard offerings, Tesla will likely keep its lineup as simple as possible.

However, the company has hinted that there is a slim possibility the Model Y L could come to the U.S. sometime late next year, but CEO Elon Musk said that it is not a guarantee.

Tesla is more concerned with self-driving efforts in the U.S., and despite calls from customers for larger vehicles, it does not seem concerned with making them available, at least not for now.

Tesla’s new Model Y Performance is set to arrive in a new market in Q1 2026, a company executive confirmed on Friday.

The lightning-fast trim level of the all-electric crossover packs a variety of new improvements, including more range and better acceleration, thanks to aerodynamic improvements and other performance-based changes.

It was initially launched in Europe, and then it made its way to the United States. However, it will soon be available in a new market: Canada.

Raj Jegannathan, a Tesla executive, confirmed on Friday that the company would be bringing its Performance trim of the Model Y to the Canadian market early next year:

Interestingly, the Model Y Performances that enter the Canadian market will likely come from Gigafactory Berlin and not Gigafactory Texas, even though it is logistically more advantageous.

There is a 25 percent tariff on U.S.-built vehicles currently, and Tesla has been sending Germany-built Model Y vehicles to Canada to avoid this and keep prices reasonable for customers.

Some Model Y owners in Canada have already confirmed that their units came from the German production facility, not the United States.

Model Y Performance deliveries have not yet started in the United States, but are slated for late November or early December.

Tesla refined the Model Y Performance’s exterior design with new front and rear fascia designs, a new performance carbon spoiler, 21″ Arachnid wheels and tires, and adaptive damping to help with better handling.

There are also new Drive Modes for better control during high-speed driving.

It also packs the same improvements as the new Model Y features over its predecessors, including acoustic glass and premium sound-damping materials for a quieter cabin, and heated and ventilated front sport seats.

In the United States, it is priced at $57,490. It will very likely be higher in Canada due to logistics costs and other factors.
