A bit less than a month after SpaceX’s first full-scale Starship prototype was partially destroyed during testing, the damaged rocket has been almost completely scrapped to make way for new and improved Starships.

On November 20th, SpaceX effectively tested the Starship Mk1 – the first full-scale prototype – to destruction, pressurizing the rocket’s tank section (lower half) until it quite literally popped its top. The pressure wave that failure created damaged almost every internal component of the massive vehicle, all but guaranteeing that SpaceX would have to scrap the vehicle and move on to new prototypes.

Those future prototypes will take advantage of the many, many lessons learned from Starhopper’s two test flights and several additional grounded tests, as well as the many learning experiences presented through Starship Mk1’s pathfinder manufacturing, assembly, and test campaign. As is SpaceX’s signature, the company is choosing to learn by building actual hardware and making the inevitable mistakes that come hand in hand with such an eccentric and ambitious program.

Above all else, SpaceX is trying to redefine the minimum infrastructure needed to build high-performance launch vehicles at a scale comparable to or even larger than NASA’s Saturn V, the largest rocket ever successfully launched. Modern rockets like Falcon 9 and Atlas V are built in relatively clean and environmentally-controlled environments and Saturn I and V – while quite a bit less sterile – were at least built inside large hangar-like facilities.

With Starship, SpaceX instead wants to build rockets even larger than Saturn V out in the elements and with a far more common (and thus affordable) workforce, (theoretically) made possible in large part thanks to its extensive use of stainless steel. Case in point, Starhopper – a low-fidelity Starship test bed – was quite literally welded together on the South Texas coast by welders far more familiar with building water towers. While not without its teething pains, Starhopper proved to be incredibly sturdy and resistant to anomalous behavior and successfully performed two separate flight tests in July and August 2019.

Three months after Starhopper’s second and final hop test, SpaceX’s Starship Mk1 tank section – the lower half of the rocket – was moved to the launch site and began a series of tanking tests. The first few tests were completed successfully and focused on searching for leaks with a neutral cryogenic liquid (likely liquid nitrogen). After the majority of those leaks were sealed, SpaceX moved into liquid oxygen load testing a few days later. For unconfirmed reasons, it turned out that that first liquid oxygen pressure test would also be Starship Mk1’s last.

On November 20th, SpaceX pressurized Starship Mk1 to its limits, with almost all of the visible creases and wrinkles in its steel surface visibly smoothing out as the supercool liquid oxygen caused frost to form on the exterior. Ultimately, SpaceX pushed the vehicle beyond its limits and its uppermost tank dome quite literally popped off of Starship’s tank section, whether the overpressure event was intentional or unexpected. The force of that overpressure event essentially sent a shockwave through Starship, crushing and warping its two remaining tank domes and transfer tubes like an aluminum soda can.

In simpler terms, very few parts of Starship Mk1 escaped unharmed, all but guaranteeing that it would not be worth the effort to repair it. Instead, SpaceX has almost entirely scrapped the prototype over a period of two weeks. According to an official statement released shortly after Mk1’s failure, SpaceX will attempt to recover and reuse as much of Mk1 as it can and those few salvageable parts will be added to an entirely new prototype, deemed Starship Mk3.

It took SpaceX about 10 days to go from ~80% of a Starship tank section to 0%. (NASASpaceflight – bocachicagal)

Although it’s disappointing that Starship Mk1 was unable to perform any kind of Raptor engine testing, let alone flight tests, it’s safe to say that the pathfinder prototype has been well worth the time and effort it took to build. Regardless of flight or engine testing, a ton of Mk1’s value lies in its utility as a hands-on, physical testbed for SpaceX employees to perform experiments and learn how to build steel rockets – and build them outside in less than friendly weather conditions.

SpaceX is in the midst of rapidly expanding its presence in Boca Chica, Texas, including a new launch control center, an expanded landing and launch pad, new production facilities, and more. The company has also just begun churning out numerous monolithic (single-weld) steel rings that will likely become part of Starship Mk3 in the near future. It will likely be several months before that next-generation prototype is as close to completion as Starship Mk1 was, but it should be well worth the wait and well worth its predecessor’s sacrifice.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner

Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.

Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.

A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.

Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.

The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.

For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.
