SpaceX Starship blew its top during rocket fueling test (updated)
Update: SpaceX has released an official statement indicating that Starship Mk1’s November 20th failure came after a decision to intentionally pressurize the rocket prototype to its limits. This likely means that the test was to max flight pressures and not an intentional burst test, so Starship’s dome failure is still a significant concern and was definitely not planned.
More importantly, SpaceX says that it had already decided to retire Starship Mk1 before any kind of flight testing, treating the vehicle as a pathfinder. Instead, SpaceX will build and use Starship Mk3 – the next Boca Chica prototype – for Starship’s first attempted skydiver-style landing and 20 km (12 mi) flight test.

SpaceX’s first full-scale Starship prototype has suffered a significant failure during testing, destroying or severely damaging large sections of the rocket. However, SpaceX CEO Elon Musk has already commented on the anomaly and is not all that concerned.
On November 20th, SpaceX – having canceled a planned road closure the day prior – unexpectedly requested a last-second road closure and entered into a much more serious round of testing with Starship Mk1, the rocket’s first full-scale prototype. This followed testing on November 18th that concluded with Starship Mk1’s very first ‘breath’ – some venting activity near the end of a tank proof test. SpaceX technicians spent the next 36 or so hours inspecting and working on Mk1, presumably looking for and patching minor leaks along its tank section.
The November 20th testing progressed far faster than the previous round of tests and Starship Mk1 was quickly venting again. Soon after that, frost began to appear on the exterior of its steel liquid oxygen and methane tanks, a telltale sign that some form of cryogenic testing was ongoing. Based on a distinct lack of activity at the nearby flare stack, SpaceX was using liquid oxygen (LOX) or liquid nitrogen (LN2) to verify that Starship performs as expected when filled with supercool propellant.
After initial venting and visible frost formation, SpaceX appeared to push forward, rapidly loading Starship Mk1 with LOX or LN2. This progress was easily visible thanks to the fact that the mass and pressure of all that cryogenic liquid made quick work of the slight imperfections on the exterior of Starship’s steel hull, turning the vehicle’s reflection from a speckled patchwork to an almost mirror-like finish. Roughly half an hour later, the otherwise peaceful scene was interrupted by the rapid failure of Starship Mk1’s upper LOX tank dome, instantly thrown several hundred feet into the air.
Seconds later, the crumpled upper half of Starship Mk1’s tank section appeared out of the clouds created and began hemorrhaging a huge volume of liquid oxygen, immediately boiling and vaporizing as it was exposed to the Earth’s comparatively white-hot atmosphere. Impressively, Starship appeared to remain functional after its top quite literally blew off, and the vehicle rapidly detanked and appeared to safe itself. Some ten minutes after the overpressure event, the freed liquid oxygen had boiled to nothing and Starship appeared to be quiet.
By all appearances, Starship Mk1 appeared to perform extremely well as an integrated system up to the point that its upper tank dome failed. The first frame from LabPadre’s stream with anything visibly amiss explicitly implicates the weld connecting the LOX dome to the cylindrical body of Starship’s LOX tank, point to a bad weld joint as the likeliest source of the failure. Although that hardware failure is unfortunate, Mk1’s loss will hopefully guide improvements in Starship’s design and manufacturing procedures.
Moving forward
Minutes after the anomaly was broadcast on several unofficial livestreams of SpaceX’s Boca Chica facilities, SpaceX CEO Elon Musk acknowledged Starship Mk1’s failure in a tweet, telegraphing a general lack of worry. Of note, Musk indicated that Mk1 was valuable mainly as a manufacturing pathfinder, entirely believable but also partially contradicting his September 2019 presentation, in which he pretty clearly stated that Mk1 would soon be launched to ~20 km to demonstrate Starship’s exotic new skydiver landing strategy.
Musk says that instead of repairing Starship Mk1, SpaceX’s Boca Chica team will move directly to Starship Mk3, a significantly more advanced design that has benefitted from the numerous lessons learned from building and flying Starhopper and fabricating Starship Mk1. The first Starship Mk3 ring appears to have already been prepared, but SpaceX’s South Texas focus has clearly been almost entirely on preparing Starship Mk1 for wet dress rehearsal, static fire, and flight tests. After today’s failure, it sounds like Mk1 will most likely be retired early and replaced as soon as possible by Mk3.
Above all else, the most important takeaway from today’s Starship Mk1 anomaly is that the vehicle was a very early prototype and SpaceX likely wants to have vehicle failures occur on the ground or in-flight. As long as no humans are at risk, pushing Starship to failure (or suffering unplanned failures like today’s) can only serve to benefit and improve the vehicle’s design, especially when the failed hardware can be recovered intact (ish) and carefully analyzed.
A step further, SpaceX is simultaneously building a second (and third) Starship prototype at its companion Cocoa, Florida facilities, and Starship Mk2 is nearly finished. Coincidentally, technicians installed its last tank dome – the same dome that failed on Mk1 – just days ago, and any insight that the Boca Chica team can gather from Mk1’s troubles will almost certainly be applied to Mk2, whether that means reinforcing its existing domes or fully replacing the upper dome with an improved design.

Tesla recently received its largest order for the all-electric Semi from Einride, a Swedish transport service, for 500 units, a groundbreaking invoice to receive before the first deliveries begin.
Even more remarkable, Einride CEO Roozbeh Charli said in a recent interview that he expects his company to take delivery of all 500 — the entire order — before the end of 2027. He even expects to have 75 Tesla Semi units in the Einride fleet before the end of this year.

Charli said the Tesla partnership was part of a broader push, along with its earlier partnership with Amazon. Einride is assisting Amazon with the use of its Saga AI platform, which helps eliminate questions about budgeting and forecasting for logistics companies.
The Semi, as well as Tesla’s production and subsequent delivery of the units to Einride, will help the company “to have a good supply of vehicles that we can deploy on the [Saga AI] platform,” Charli said. “Tesla is also a relationship we’ve had for a while, and as the Tesla Semi deliveries are firming up, we decided to do a larger commitment to that and deploy that on our platform.”
In its initial announcement, Einride said it anticipated taking delivery of the trucks over the next two years, but now it appears the company is expecting all 500 units within the next 16 months.
Built at a dedicated factory in Sparks, Nevada, the Tesla Semi has been perhaps the biggest and most intensive testing process the company has ever had for a single vehicle model. For the past several years, Tesla has been working with many companies, most notably Frito-Lay and PepsiCo, to gain knowledge on the performance on regional routes.
Tesla plans to launch the Semi officially on September 24, five months after production started ramping.
Additionally, drivers have said they are happy about the Semi’s performance and that its numerous safety and productivity features have made their jobs and routes much easier.
Tesla Cybercab is using a unique strategy for picking up the correct rider, which is a crucial part of ride-hailing to ensure people end up in the right place and are charged the correct price.
Cybercab will utilize an RGB strip in its front light bar that will illuminate in a variety of different colors to mark itself.
This identifying mark will also appear in the Robotaxi app, giving riders in the same location a notable distinction in an effort to avoid any confusion regarding who should get in each vehicle.

Other ride-hailing services use similar strategies: Lyft and Uber rides are recognizable through driver identity, vehicle type and color, as well as license plate. Waymo will display the rider’s initials on top of the vehicle, letting them know that the specific vehicle for them has arrived.
Tesla’s strategy is unique and interesting, but there are some flaws. Cybercab’s main purpose is aimed toward being an autonomous ride for all, including those who have disabilities like being blind or even color blind.
Tesla will likely have something in the pipeline for those who cannot see colors or have limited vision. There will definitely be multiple ways to identify which vehicle is the one that “you” specifically ordered.
Cybercab is set to start giving public rides next Thursday, September 3, in Austin, as it announced a dedicated event last week and invited many members of the Tesla community.
Additionally, members of the public will be invited as well. Tesla has been offering employee rides in Cybercab for nearly two months.
Tesla has said goodbye to one customization option for its vehicles: the wrap service it launched several years ago.
After launching an in-house wrap service in August 2020 for the first time in China. In the U.S., it launched in October 2023. Tesla continued to expand the program and adjust it with better pricing and fewer options for the Cybertruck.
By December 2023, it was giving owners of the Model 3, Model Y, and the Cybertruck the opportunity to give their vehicle a fresh look with a vinyl wrap.

It was only available in five locations: Costa Mesa, Oceanside, Santa Clara, West Covina, all in California, and Seattle, Washington.
However, Tesla made some big adjustments to its shop, and the wrap service is officially gone:
Tesla has made a LOT of changes to its online shop recently — price increases, price cuts, new options, and several products being removed entirely.
Some of the biggest increases are wheel covers. 👀

Wraps are very popular across the Tesla lineup, especially since the company offers relatively few colors. Many choose to wrap their Teslas with interesting colors, patterns, or even finishes, turning their cars from glossy to satin or matte.
However, Tesla’s wrap service was so limited geographically that it never really had a chance to get off the ground or compete with local shops. Every area in the United States is now overflowing with detailing shops, mobile detailers, and other automotive specialists, many of whom perform wrap services.
Tesla’s service was confined to the Pacific time zone and only spanned across two states. It was never going to be something Tesla was a major competitor in, nor was it going to disrupt the wrapping industry. Now that the program has ended, it seems pretty ideal to believe it was always going to be a short-term thing.
Along with the wrap service, Tesla removed several other products, but nothing too crazy. The Model 3 Door Pocket and Cupholder Liners, the Model S 19″ Magnetite Wheel and Winter Tire Package, Model X/Y Ski/Snowboard Carrier for Hitch Rack, Tesla’s Electric Summer Party Tee, and the Electric Summer Tee were the other items the company totally eliminated from its online shop.
