SpaceX ‘tops off’ its South Texas Starship prototype with one final steel dome
On September 14th, South Texas SpaceX technicians lifted Starship Mk1’s third and final tank dome and began to attach it atop the prototype’s steel tank section, this time making use of a new method of integration.
This progress comes just two weeks before CEO Elon Musk is expected to present a detailed update on Starship’s newest design iteration. Musk is hopeful that – come his September 28th presentation – Starship Mk1 will be nearly complete and ready for its inaugural flight, a milestone that could come as early as October 13th according to Starship documents filed with the FCC.
This latest installation is likely either the last ring (or nearly so) to be stacked on top of Starship Mk1, paving the way for the eventual attachment of the spacecraft’s conical nose section and the fleshing out of its many internal subsystems and aerodynamic control surfaces. This particular milestone involved the attachment of Starship’s third and final tank bulkhead – in this case, the upper dome of the prototype’s liquid oxygen tank. Excluding hardware that might eventually be installed on the dome itself, this means that Starship Mk1’s tank and engine section has essentially been ‘topped off’.
As previously estimated by the author, this particular tank dome installation – the fifth completed by SpaceX’s Mk1 and Mk2 Starship teams – was done in a manner thus far unique. All previous installations have seen SpaceX technicians lower the domes – completed aside from one vertical weld for flexibility – inside the Starship’s cylindrical tank section. The steel domes are then carefully spot-welded to the side of the tank in their proper place – all while being supported by a large crane – before technicians can complete a seamless ring weld around their entire circumference.

This time around, SpaceX welded the upper tank dome to its companion ring section while both elements were still staged on the ground. Once the dome was completely welded to the steel ring and a dome cap was installed to seal off the top, the ring segment was craned atop Starhip Mk1 on September 14th. It’s possible that this was planned all along for each Starship’s third and final tank dome, but the way CEO Elon Musk has previously described SpaceX’s semi-competitive Mk1 and Mk2 builds suggests that it may instead be a new assembly strategy that evolved in just the last month or two.

Instead of having to do the work of fitting, attaching, and ring-welding the bulkhead to Starship’s tank section 50-100 feet above ground, with all the associated rigging, scaffolding, and challenges such a work environment demands, technicians were able to do the majority of that work at ground-level. This method seems to offload the added challenge of dome installation to the vertical ring installation process, effectively merging the two processes into one much simpler (and safer) feat.
The fact that Starship Mk1’s tank section has now been capped (aside from several small access ports) indicates that all large, plumbing-related components have been installed inside the steel prototype. Up next for Starship Mk1 is the installation of its landing legs/fins/wings (at least two of which have already arrived on-site), canards, and a variety of smaller additions like valves, thrusters, ground connection points, and much more.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.

The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.
As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality.
“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.
When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.
After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”
“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.
Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.
During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.
As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.
Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.
While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing.
“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.
“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said.
The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.
Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”
Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.
“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all.
“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.
