SpaceX Starship just aced another explosive tank test and Elon Musk has the results [video]
SpaceX has successfully repaired a leak in a Starship prototype, filled the giant tank with an ultra-cold liquid, and pressurized it until it (spectacularly) popped — and Elon Musk has the preliminary results.
Designed to determine the quality and capabilities of SpaceX’s current manufacturing and integration procedures, the company technically performed its first explosive Starship test back in November 2019, when it decided that the first full-scale prototype – Starship Mk1 – was not fit to fly. Instead of entering the final stages of assembly with a vehicle that SpaceX simply couldn’t be sure would survive the rigors of even a low-stress flight test, the massive vehicle’s tank section was installed at the company’s South Texas launch facilities and pressurized with liquid nitrogen until it burst.
Built almost entirely unprotected on the South Texas coast, Starship Mk1 simply wasn’t up to the standards needed for SpaceX to trust that the giant rocket would survive the stresses of flight. Much like Falcon 9, Starship and its Super Heavy booster will be structurally stable while their tanks are empty, but a great deal of additional (and absolutely critical) structural strength will be added by pressurizing those tanks with a combination of liquid and gaseous propellant. Achieving the required pressures, however, can be a major challenge and the purpose of test tanks like the one above is to prove that the company is up to the challenge. According to Elon Musk, after tonight’s test, SpaceX almost certainly is.
In all truthfulness, the real start of explosive Starship pressure testing actually happened all the way back in 2017 when SpaceX intentionally pressurized a vast 12m-diameter (40 ft) carbon composite tank until it popped. Back then, Starship was known as Big Falcon Rocket (BFR) and was designed to use carbon fiber composites for nearly all of its structure — propellant tanks included.
According to CEO Elon Musk, said carbon composite tank met SpaceX’s expectations (i.e. the necessary pressures for flight) and was pushed to 2.3 bar (33 psi) before it burst in a rather spectacular fashion, launching almost 100 m (300 ft) into the air. Around 2.5 years after that test, it’s believed that Starship Mk1 reached something like 3-5 bar before it popped, and Musk recently revealed that the new steel Starship and Super Heavy designs will require tanks pressures of at least 6 bar (90 psi) to survive the stresses of orbital flight.
-->Thankfully, although Starship Mk1 didn’t achieve those necessary pressures, the prototype was effectively a worst-case scenario for manufacturing and assembly, revealing the rather unsurprising reality that SpaceX needed to improve its uniquely sparse methods of production and assembly. Although the stainless steel SpaceX settled on for Starship is much more tolerant than aluminum or most other metals when it comes to welding, steel welds still suffer if exposed to more than a minor breeze, as wind will cause the welded metal to cool less than uniformly.
With the latest series of steel Starship tank prototypes, SpaceX has significantly improved its production infrastructure, finally offering at least a semblance of protection against the elements. Based on the first test tank’s explosive performance on January 10th, those improvements have paid dividends. According to Musk, test tank #1 made it all the way to 7.1 bar (105 psi) before it burst and test tank #2 reportedly did even better.
Meanwhile, SpaceX’s South Texas team has already finished and partially tested a second Starship test tank, ultimately reaching 7.5 bar with water before a small leak sprung on January 27th. Over the last 24 hours, technicians have worked to repair the apparently minor damage and began filling the Starship tank with ultra-cold liquid nitrogen (boiling point: -196°C / -320°F) around 5:30 pm CST (23:30 UTC) on January 28th. After filling with liquid nitrogen, SpaceX kept the steel tank topped off for several hours. The likely purpose behind that otherwise odd move: something called cryogenic hardening. By exposing certain types of steel to liquid nitrogen temperatures, the material can be dramatically strengthened in some regards.
Around four hours after Tuesday evening’s testing began, the Starship tank prototype appeared to develop a significant leak in its upper dome, hemorrhaging liquid nitrogen that immediately produced large clouds after coming into contact with the South Texas air. As it turns out, whatever was observed was almost certainly not a leak: 30 or so minutes later, the tank was pressurized to failure, releasing a spectacular tidal wave of liquid nitrogen that doused the surrounding area, temporarily killing nearby floodlights and creating a near-zero-visibility storm of fog.
We’ll have to wait for dawn tomorrow to see the extent of the damage, but it appears that Test Tank #2’s demise was dramatically more violent than its predecessor — a largely expected side effect of performing the pressure test with a cryogenic liquid. In fact, just minutes after it appeared to fail, Elon Musk revealed that the second test tank had burst around 8.5 bar (~125 psi), soundly trouncing all records set by earlier tests and suggesting SpaceX is unequivocally ready to begin building the first orbital Starships. Critically, Musk had previously indicated that if Starship’s tanks could survive up to 8.5 bar, SpaceX would have the minimum safety margins it needs to deem Starship safe enough for astronauts.
In other words, if Test Tank #2 really did reach 8.5 bar, SpaceX has effectively solved the biggest structural engineering challenge its Starship program faces, kicking the doors wide open for the more or less immediate mass-production of the first giant orbital-class spacecraft. As it turns out, what Musk has deemed as the first “orbital” Starship prototype – ‘SN01’ – is already under construction, and it’s safe to say that any lessons learned from January 28th’s cryogenic pressure test will be fed back into SN01 and all future prototypes.

Elon Musk said in late November that he’s “tried to warn” legacy automakers and “even offered to license Tesla Full Self-Driving, but they don’t want it,” expressing frustration with companies that refuse to adopt the company’s suite, which will eventually be autonomous.
Tesla has long established itself as the leader in self-driving technology, especially in the United States. Although there are formidable competitors, Tesla’s FSD suite is the most robust and is not limited to certain areas or roadways. It operates anywhere and everywhere.
The company’s current position as the leader in self-driving tech is being ignored by legacy automakers, a parallel to what Tesla’s position was with EV development over a decade ago, which was also ignored by competitors.
The reluctance mirrors how legacy automakers initially dismissed EVs, only to scramble in catch-up mode years later–a pattern that highlights their historical underestimation of disruptive innovations from Tesla.
Elon Musk’s Self-Driving Licensing Attempts
Musk and Tesla have tried to push Full Self-Driving to other car companies, with no true suitors, despite ongoing conversations for years. Tesla’s FSD is aiming to become more robust through comprehensive data collection and a larger fleet, something the company has tried to establish through a subscription program, free trials, and other strategies.
Tesla CEO Elon Musk sends rivals dire warning about Full Self-Driving
However, competing companies have not wanted to license FSD for a handful of speculative reasons: competitive pride, regulatory concerns, high costs, or preference for in-house development.
Déjà vu All Over Again
Tesla tried to portray the importance of EVs long ago, as in the 2010s, executives from companies like Ford and GM downplayed the importance of sustainable powertrains as niche or unprofitable.
Musk once said in a 2014 interview that rivals woke up to electric powertrains when the Model S started to disrupt things and gained some market share. Things got really serious upon the launch of the Model 3 in 2017, as a mass-market vehicle was what Tesla was missing from its lineup.
This caused legacy companies to truly wake up; they were losing market share to Tesla’s new and exciting tech that offered less maintenance, a fresh take on passenger auto, and other advantages. They were late to the party, and although they have all launched vehicles of their own, they still lag in two major areas: sales and infrastructure, leaning on Tesla for the latter.
I’ve tried to warn them and even offered to license Tesla FSD, but they don’t want it! Crazy …
When legacy auto does occasionally reach out, they tepidly discuss implementing FSD for a tiny program in 5 years with unworkable requirements for Tesla, so pointless. 🤷♂️

Musk’s past warnings have been plentiful. In 2017, he responded to critics who stated Tesla was chasing subsidies. He responded, “Few people know that we started Tesla when GM forcibly recalled all electric cars from customers in 2003 and then crushed them in a junkyard,” adding that “they would be doing nothing” on EVs without Tesla’s efforts.
Companies laughed off Tesla’s prowess with EVs, only to realize they had made a grave mistake later on.
It looks to be happening once again.
A Pattern of Underestimation
Both EVs and self-driving tech represent major paradigm shifts that legacy players view as threats to their established business models; it’s hard to change. However, these early push-aways from new tech only result in reactive strategies later on, usually resulting in what pains they are facing now.
Ford is scaling back its EV efforts, and GM’s projects are hurting. Although they both have in-house self-driving projects, they are falling well behind the progress of Tesla and even other competitors.
It is getting to a point where short-term risk will become a long-term setback, and they may have to rely on a company to pull them out of a tough situation later on, just as it did with Tesla and EV charging infrastructure.
Tesla has continued to innovate, while legacy automakers have lagged behind, and it has cost them dearly.
Implications and Future Outlook
Moving forward, Tesla’s progress will continue to accelerate, while a dismissive attitude by other companies will continue to penalize them, especially as time goes on. Falling further behind in self-driving could eventually lead to market share erosion, as autonomy could be a crucial part of vehicle marketing within the next few years.
Eventually, companies could be forced into joint partnerships as economic pressures mount. Some companies did this with EVs, but it has not resulted in very much.
Self-driving efforts are not only a strength for companies themselves, but they also contribute to other things, like affordability and safety.
Tesla has exhibited data that specifically shows its self-driving tech is safer than human drivers, most recently by a considerable margin. This would help with eliminating accidents and making roads safer.
Tesla’s new Safety Report shows Autopilot is nine times safer than humans
Additionally, competition in the market is a good thing, as it drives costs down and helps innovation continue on an upward trend.
Conclusion
The parallels are unmistakable: a decade ago, legacy automakers laughed off electric vehicles as toys for tree-huggers, crushed their own EV programs, and bet everything on the internal-combustion status quo–only to watch Tesla redefine the industry while they scrambled for billions in catch-up capital.
Today, the same companies are turning down repeated offers to license Tesla’s Full Self-Driving technology, insisting they can build better autonomy in-house, even as their own programs stumble through recalls, layoffs, and missed milestones. History is not merely rhyming; it is repeating almost note-for-note.
Elon Musk has spent twenty years warning that the auto industry’s bureaucratic inertia and short-term thinking will leave it stranded on the wrong side of technological revolutions. The question is no longer whether Tesla is ahead–it is whether the giants of Detroit, Stuttgart, and Toyota will finally listen before the next wave leaves them watching another leader pull away in the rear-view mirror.
This time, the stakes are not just market share; they are the very definition of what a car will be in the decades ahead.

Waymo driverless taxi drives directly into active LAPD standoff
No injuries occurred, and the passengers inside the vehicle were safely transported to their destination, as per a Waymo representative.
A video posted on social media has shown an occupied Waymo driverless taxi driving directly into the middle of an active LAPD standoff in downtown Los Angeles.
As could be seen in the short video, which was initially posted on Instagram by user Alex Choi, a Waymo driverless taxi drove directly into the middle of an active LAPD standoff in downtown Los Angeles.
The driverless taxi made an unprotected left turn despite what appeared to be a red light, briefly entering a police perimeter. At the time, officers seemed to be giving commands to a prone suspect on the ground, who looked quite surprised at the sudden presence of the driverless vehicle.
People on the sidewalk, including the person who was filming the video, could be heard chuckling at the Waymo’s strange behavior.
The Waymo reportedly cleared the area within seconds. No injuries occurred, and the passengers inside the vehicle were safely transported to their destination, as per a Waymo representative. Still, the video spread across social media, with numerous netizens poking fun at the gaffe.
-->Others also pointed out that such a gaffe would have resulted in widespread controversy had the vehicle involved been a Tesla on FSD. Tesla is constantly under scrutiny, with TSLA shorts and similar groups actively trying to put down the company’s FSD program.
A Tesla on FSD or Robotaxi accidentally driving into an active police standoff would likely cause lawsuits, nonstop media coverage, and calls for a worldwide ban, at the least.
This was one of the reasons why even minor traffic infractions committed by the company’s Robotaxis during their initial rollout in Austin received nationwide media attention. This particular Waymo incident, however, will likely not receive as much coverage.
Tesla Model Y demand in China is through the roof, and new delivery dates show the company has already sold out its allocation of the all-electric crossover for 2025.
The Model Y has been the most popular vehicle in the world in both of the last two years, outpacing incredibly popular vehicles like the Toyota RAV 4. In China, the EV market is substantially more saturated, with more competitors than in any other market.
However, Tesla has been kind to the Chinese market, as it has launched trim levels for the Model Y in the country that are not available anywhere else. Demand has been strong for the Model Y in China; it ranks in the top 5 of all EVs in the country, trailing the BYD Seagull, Wuling Hongguang Mini EV, and the Geely Galaxy Xingyuan.
The other three models ahead of the Model Y are priced substantially lower.
Tesla is still dealing with strong demand for the Model Y, and the company is now pushing delivery dates to early 2026, meaning the vehicle is sold out for the year:

Tesla experienced a 9.9 percent year-over-year rise in its China-made EV sales for November, meaning there is some serious potential for the automaker moving into next year despite increased competition.
There have been a lot of questions surrounding how Tesla would perform globally with more competition, but it seems to have a good grasp of various markets because of its vehicles, its charging infrastructure, and its Full Self-Driving (FSD) suite, which has been expanding to more countries as of late.
Tesla Model Y is still China’s best-selling premium EV through October
Tesla holds a dominating lead in the United States with EV registrations, and performs incredibly well in several European countries.
With demand in China looking strong, it will be interesting to see how the company ends the year in terms of global deliveries.
