SpaceX’s upgraded Starship gets frosty during cryogenic proof test
Update: SpaceX is well into Starship SN15’s first cryogenic proof test and is in the process of loading the upgraded steel rocket with hundreds of tons of supercool liquid nitrogen (LN2).
As a result, the 50m (165 ft) tall spacecraft and upper stage prototype has developed a coating of frost as its extremely cold cargo quite literally freezes the humid South Texas air onto its steel skin. Stay tuned for updates on the performance of Starship SN15 during its first ‘cryo proof’ and what that means for engine installation and its next big test – a triple-Raptor static fire.
SpaceX has cleared its suborbital South Texas launch pad of all personnel, clearing the way for the Starship serial number 15 (SN15) to kick off the first in a series of big tests.
Outfitted with “hundreds” of upgrades relative to late full-size predecessors SN8, SN9, SN10, and SN11, there’s a chance that SN15 holds the key to SpaceX’s first completely successful high-altitude Starship launch and landing.
Though Starship SN10 managed to land in one piece last month and both it and its three siblings successfully reached nominal 10-12.5 km (6-8 mi) apogees, averaged more than six minutes of controlled flight, and restarted at least one of three Raptor engines without issue, SN10 explodes minutes after touchdown and the other ships suffered various failures of their own 10-30 seconds before landing. At least one vehicle loss (Starship SN9) can be blamed on the failure of one of two Raptor engines to properly ignite.
Starship SN8 made it seconds away from an intact touchdown on the first try before an issue with its advanced pressurization system starved its Raptor engines of fuel. Starship SN10 landed hard – partially leading to its demise – because the quick-fix SpaceX implemented to deal with the pressurization issues SN8 surfaced caused Raptor engines to ingest helium, dramatically lowering their thrust and performance. CEO Elon Musk believes SN11’s even earlier demise was caused by a high-pressure methane leak on one Raptor engine that destroyed avionics and led to a hard-start and violent explosion during landing burn ignition.
While many – if not most – of Starship SN15’s myriad upgrades likely began before most of the SN8-SN11 failure modes were uncovered, it’s not unlikely that SpaceX was already aware of potential weak points and working to fix them. The company’s philosophy largely matches agile development popular in software industries – namely the development of a minimum viable product, followed by a cycle of iterative testing and refinement until a given product is reliably achieving all of its foundational goals.
Now, it’s up to Starship SN15 (as well as SN16, SN17, SN18, and possibly SN19) to carry the torch forward and demonstrate clear progress towards the goal of fielding a reliable, reusable, building-sized spacecraft and upper stage. To do that, SN15 must first act as a pathfinder for those upgrades, beginning with qualification tests on the ground.
The first of those – likely a cryogenic proof test with liquid nitrogen – is scheduled as early as today, sometime between now and 8pm CDT (UTC-5). Stay tuned for updates as Starship SN15 (hopefully) gets frosty for the first time.

Man credits Grok AI with saving his life after ER missed near-ruptured appendix
The AI flagged some of the man’s symptoms and urged him to return to the ER immediately and demand a CT scan.
A 49-year-old man has stated that xAI’s Grok ended up saving his life when the large language model identified a near-ruptured appendix that his first ER visit dismissed as acid reflux.
After being sent home from the ER, the man asked Grok to analyze his symptoms. The AI flagged some of the man’s symptoms and urged him to return immediately and demand a CT scan. The scan confirmed that something far worse than acid reflux was indeed going on.
Grok spotted what a doctor missed
In a post on Reddit, u/Tykjen noted that for 24 hours straight, he had a constant “razor-blade-level” abdominal pain that forced him into a fetal position. He had no fever or visible signs. He went to the ER, where a doctor pressed his soft belly, prescribed acid blockers, and sent him home.
The acid blockers didn’t work, and the man’s pain remained intense. He then decided to open a year-long chat he had with Grok and listed every detail that he was experiencing. The AI responded quickly. “Grok immediately flagged perforated ulcer or atypical appendicitis, told me the exact red-flag pattern I was describing, and basically said “go back right now and ask for a CT,” the man wrote in his post.
He copied Grok’s reasoning, returned to the ER, and insisted on the scan. The CT scan ultimately showed an inflamed appendix on the verge of rupture. Six hours later, the appendix was out. The man said the pain has completely vanished, and he woke up laughing under anesthesia. He was discharged the next day.

AI doctors could very well be welcomed
In the replies to his Reddit post, u/Tykjen further explained that he specifically avoided telling doctors that Grok, an AI, suggested he get a CT scan. “I did not tell them on the second visit that Grok recommended the CT scan. I had to lie. I told them my sister who’s a nurse told me to ask for the scan,” the man wrote.
One commenter noted that the use of AI in medicine will likely be welcomed, stating that “If AI could take doctors’ jobs one day, I will be happy. Doctors just don’t care anymore. It’s all a paycheck.” The Redditor replied with, “Sadly yes. That is what it felt like after the first visit. And the following night could have been my last.”
Elon Musk has been very optimistic about the potential of robots like Tesla Optimus in the medical field. Provided that they are able to achieve human-level articulation in their hands, and Tesla is able to bring down their cost through mass manufacturing, the era of AI-powered medical care could very well be closer than expected.

Tesla expands Model 3 lineup in Europe with most affordable variant yet
The Model 3 Standard still delivers more than 300 miles of range, potentially making it an attractive option for budget-conscious buyers.
Tesla has introduced a lower-priced Model 3 variant in Europe, expanding the lineup just two months after the vehicle’s U.S. debut. The Model 3 Standard still delivers more than 300 miles (480 km) of range, potentially making it an attractive option for budget-conscious buyers.
Tesla’s pricing strategy
The Model 3 Standard arrives as Tesla contends with declining registrations in several countries across Europe, where sales have not fully offset shifting consumer preferences. Many buyers have turned to options such as Volkswagen’s ID.3 and BYD’s Atto 3, both of which have benefited from aggressive pricing.
By removing select premium finishes and features, Tesla positioned the new Model 3 Standard as an “ultra-low cost of ownership” option of its all-electric sedan. Pricing comes in at €37,970 in Germany, NOK 330,056 in Norway, and SEK 449,990 in Sweden, depending on market. This places the Model 3 Standard well below the “premium” Model 3 trim, which starts at €45,970 in Germany.
Deliveries for the Standard model are expected to begin in the first quarter of 2026, giving Tesla an entry-level foothold in a segment that’s increasingly defined by sub-€40,000 offerings.
Tesla’s affordable vehicle push
The low-cost Model 3 follows October’s launch of a similarly positioned Model Y variant, signaling a broader shift in Tesla’s product strategy. While CEO Elon Musk has moved the company toward AI-driven initiatives such as robotaxis and humanoid robots, lower-priced vehicles remain necessary to support the company’s revenue in the near term.
Reports have indicated that Tesla previously abandoned plans for an all-new $25,000 EV, with the company opting to create cheaper versions of existing platforms instead. Analysts have flagged possible cannibalization of higher-margin models, but the move aims to counter an influx of aggressively priced entrants from China and Europe, many of which sell below $30,000. With the new Model 3 Standard, Tesla is reinforcing its volume strategy in Europe’s increasingly competitive EV landscape.

Tesla FSD (Supervised) stuns Germany’s biggest car magazine
FSD Supervised recognized construction zones, braked early for pedestrians, and yielded politely on narrow streets.
Tesla’s upcoming FSD Supervised system, set for a European debut pending regulatory approval, is showing notably refined behavior in real-world testing, including construction zones, pedestrian detection, and lane changes, as per a recent demonstration ride in Berlin.
While the system still required driver oversight, its smooth braking, steering, and decision-making illustrated how far Tesla’s driver-assistance technology has advanced ahead of a potential 2026 rollout.
FSD’s maturity in dense city driving
During the Berlin test ride with Auto Bild, Germany’s largest automotive publication, a Tesla Model 3 running FSD handled complex traffic with minimal intervention, autonomously managing braking, acceleration, steering, and overtaking up to 140 km/h. It recognized construction zones, braked early for pedestrians, and yielded politely on narrow streets.
Only one manual override was required when the system misread a converted one-way route, an example, Tesla stated, of the continuous learning baked into its vision-based architecture.
Robin Hornig of Auto Bild summed up his experience with FSD Supervised with a glowing review of the system. As per the reporter, FSD Supervised already exceeds humans with its all-around vision. “Tesla FSD Supervised sees more than I do. It doesn’t get distracted and never gets tired. I like to think I’m a good driver, but I can’t match this system’s all-around vision. It’s at its best when both work together: my experience and the Tesla’s constant attention,” the journalist wrote.
Tesla FSD in Europe
FSD Supervised is still a driver-assistance system rather than autonomous driving. Still, Auto Bild noted that Tesla’s 360-degree camera suite, constant monitoring, and high computing power mark a sizable leap from earlier iterations. Already active in the U.S., China, and several other regions, the system is currently navigating Europe’s approval pipeline. Tesla has applied for an exemption in the Netherlands, aiming to launch the feature through a free software update as early as February 2026.
What Tesla demonstrated in Berlin mirrors capabilities already common in China and the U.S., where rival automakers have rolled out hands-free or city-navigation systems. Europe, however, remains behind due to a stricter certification environment, though Tesla is currently hard at work pushing for FSD Supervised’s approval in several countries in the region.
