SpaceX scraps first Starship prototype to make way for new and improved rockets
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.
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.

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 design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

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 (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.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Show room is empty. I asked and they have sold the demo cars too. Delivery numbers better be outstanding! pic.twitter.com/jq5N28Q6tZ

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.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

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.

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.

The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
