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.

Tesla is launching its solution to end Supercharger fights once and for all, eliminating any confusion on who is to charge next at a congested location.
Last year, a notable incident at a Tesla Supercharger led to a fight, and it all stemmed from a disagreement over who arrived at the location first.
Congestion at Tesla Superchargers is a pretty infrequent occurrence for most of us, but there are more congested and popular areas where wait times can be extensive. An unfortunate growing pain of EV ownership is the plain fact that chargers are not as available as gas pumps, and there are, at times, lines to charge.
This can cause tensions to flare and people to get entitled when visiting Superchargers. Nobody wants to spend hours at a Supercharger, but now, there will be no more confusion when there is a queue, and that’s thanks to Tesla’s new Virtual Queue for Superchargers.
Tesla is finally starting to build out the Virtual Supercharger Queue, according to Not a Tesla App, but it still relies on drivers to make it work.
When a driver is near a Supercharger that is full, a message will pop up on the Tesla App, using the driver’s location to determine their eligibility to join the virtual queue.
The app states:
“While the app is closed, Tesla uses your location to notify you of accurate wait times at Superchargers when you arrive.”
Another message within the app states:
“There is a waitlist to charge. Are you sure you want to start a charging session now?”
This sounds as if it will require drivers to act appropriately and only plug in when the app prompts them to do so, by letting them know it is their turn.
The app will notify the driver of their position in the queue, as well as how many vehicles are ahead of them.
Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means
The company announced a while back that it would be working on a solution for this issue. Personally, I’ve only had to wait at a Supercharger for a charge on one occasion, and there was a line of between 3 and 10 cars during this singular occurrence.
I’m out at the Lancaster, PA Supercharger and showed up with a queue of three vehicles.
It’s now up to five and there have been several issues with order of arrival and confusion about who is first.
Any update on Supercharger queue? @elonmusk @aelluswamy @r_jegaa
— TESLARATI (@Teslarati) January 31, 2026
There were no conflicts or arguments about who had arrived first, but there was some discussion between several drivers during my time there about who was to charge first. Throw a non-Tesla EV into the mix, one that can only charge at a pull-in spot, and that causes even more of a complication.

Tesla offers awesome Free Supercharging incentive on an unexpected vehicle
In the past, Tesla has used Free Supercharging to incentivize the purchase of its expensive vehicles, like the Model S and Model X. However, those vehicles are leaving the company lineup, and Tesla saw a benefit from applying the incentive to another car.
Tesla is offering an awesome new Free Supercharging incentive on a vehicle that is sort of unexpected.
In the past, Tesla has used Free Supercharging to incentivize the purchase of its expensive vehicles, like the Model S and Model X. However, those vehicles are leaving the company lineup, and Tesla saw a benefit from applying the incentive to another car.
Tesla North America has introduced a compelling new incentive aimed at boosting Model 3 sales. Starting with orders placed on or after April 24, buyers of the Model 3 Premium (Long Range) and Performance variants in the United States will receive one full year of complimentary Supercharging.
The offer applies exclusively to new vehicle orders and does not extend to existing owners or other trims like the base Rear-Wheel Drive model.
New orders of Model 3 Premium & Performance now come with 1 year of free Supercharging 🇺🇸
Also, all Teslas pay the lowest Supercharging rates – all others pay a ~40% premium or need a subscription
— Tesla North America (@tesla_na) April 24, 2026
The announcement underscores Tesla’s continued dominance in EV charging infrastructure.
While the incentive provides 12 months of zero-cost access to the Supercharger network, Tesla also reiterated its pricing structure: all Tesla vehicles receive the lowest Supercharging rates.
Non-Tesla EVs, by contrast, pay approximately 40 percent more per kWh or must purchase a subscription to access the network at standard rates. This tiered approach highlights the strategic value of owning a Tesla, where seamless integration with the world’s largest and most reliable fast-charging network remains a key differentiator.
For prospective buyers, the savings can be substantial. Depending on driving habits, a typical Model 3 owner might log 12,000–15,000 miles annually.
With average Supercharging costs around $0.40–$0.50 per kWh, one year of free sessions could translate to $800–$1,200 in avoided expenses.
That effectively lowers the total cost of ownership and makes long-distance travel more affordable from day one. Early delivery customers have already noted similar past incentives, with one Cybertruck owner reporting over $2,400 saved in just six months under similar offers that Tesla has deployed in the past.
The timing of the offer appears strategic. Tesla faces growing competition from other automakers expanding their own charging networks and offering aggressive EV incentives.
By bundling free Supercharging rather than discounting the vehicle’s MSRP, Tesla preserves perceived value while directly addressing one of the biggest barriers for new EV adopters: charging costs and convenience.
The move also encourages higher-mileage use of the network, generating valuable real-world data for Tesla’s autonomous driving development.
Why Tesla would apply this incentive to the Model 3 is pretty interesting. It usually is a pretty good incentive to move units out the door, so there’s some speculation whether Tesla is planning to launch new upgrades to the mass-market sedan in the coming months, and the company wants to move what will be outdated units from its inventory.
However, there is also just the idea that Tesla could be attempting to stimulate some early quarter demand for the Model 3, especially as the Model Y continues to sell very well. Tesla’s loss of the $7,500 EV tax credit last year had an impact on sales, and Tesla might be testing some formidable options to see if it can add some demand once again.

Tesla Cybercab gets crazy change as mass production begins
Tesla has officially kicked off mass production of its groundbreaking Cybercab robotaxi at Giga Texas, and the first units rolling off the line feature a striking transformation that’s turning heads across the EV community.
Tesla Cybercab has evidently received a pretty crazy change from an aesthetic standpoint, as the company has made the decision to offer an additional finish on the vehicle as mass production is starting.
Tesla has officially kicked off mass production of its groundbreaking Cybercab robotaxi at Giga Texas, and the first units rolling off the line feature a striking transformation that’s turning heads across the EV community.
VIN Zero—the very first production Cybercab—showcases a vibrant champagne gold exterior with a high-gloss finish, a dramatic departure from the flat, matte-wrapped prototypes that debuted at the 2024 “We, Robot” event.

This glossy sheen is a pretty big pivot from what was initially shown by Tesla. The company has maintained a pretty flat tone in terms of anything related to custom colors or finishes.
A specialized clear coat or process delivers the deep, reflective gloss without conventional painting. The result is a premium, mirror-like shine, and it looks pretty good, and gives the compact two-seater a more luxurious and futuristic presence than the subdued matte prototypes.
Photos shared by Tesla community members reveal VIN Zero in a showroom-like setting at Giga Texas, highlighting refined panel gaps, large aero wheel covers, and the signature no-steering-wheel, no-pedals interior optimized for full autonomy.
The open frunk in some images offers a glimpse of practical storage, while the overall build quality appears more polished than that of test mules.
This glossy evolution aligns with Tesla’s broader production ramp. After the first unit in February 2026, the company has shifted to volume manufacturing, with dozens of units already spotted in outbound lots. CEO Elon Musk and the team aim for hundreds per week, paving the way for unsupervised FSD robotaxi networks that could slash ride costs to pennies per mile.
The Cybercab holds Tesla’s grand ambitions of operating a full-service ride-hailing service without any drivers in its grasp. Tesla has yet to solve autonomy, but is well on its way, and although its timelines are usually a bit off, improvements often come through the Over-the-Air updates to the Full Self-Driving suite.
