SpaceX CEO Elon Musk kills mini BFR spaceship 12 days after announcing it
Less than two weeks after SpaceX CEO Elon Musk announced that Falcon 9’s “second stage [would] be upgraded…like a mini-BFR Ship” to prove lightweight heatshield and hypersonic control surface technologies, Musk took to Twitter to assert that the mini BFR spaceship project was dead, despite having stated that SpaceX was working to launch that test article into orbit as early as June 2019 just 12 days prior.
From a public perspective, the status of SpaceX’s next-gen rocket program (known as BFR) is effectively up in the air after several cryptic and seemingly contradictory statements from the company’s CEO and chief engineer.
No, we’re just going to accelerate BFR
— Elon Musk (@elonmusk) November 20, 2018
On Nov. 17, Musk tweeted that BFR – last updated in September 2018 alongside a statement that “this is [likely] the the final iteration [of BFR] in terms of broad architectural decisions” – had already been redesigned, going so far as to describe it as a “radical change”. What that radical design change might be is almost entirely unclear, although Musk has now twice stated that the purpose of these changes (and the whiplash-inducing cancellation of the mini-spaceship) is to “accelerate BFR”.
Radical change

As of now, SpaceX appears to have just completed a massive 9-meter diameter composite tank dome in the company’s temporary Port of Los Angeles tent, where a small but growing team of engineers and technicians are working to realize some version of the company’s next-generation rocket. That group has been working in near-silence for the better part of a year and has accepted delivery of and set up a wide range of custom-built tooling for carbon composite fabrication, and has even managed to get that tooling producing massive composite parts that are expected to eventually make up the structure of a spaceship prototype.
That prototype would eventually be shipped to South Texas, where SpaceX is constructing an entirely new facility from scratch to test the design, technology, and operation of the first full-scale BFR spaceship (BFS). As of a few months ago, the plan was to begin those hop tests before the end of 2019, but it’s no longer clear if SpaceX still intends to build a prototype spaceship to conduct hops and high-speed, high-altitude test flights.

Responsibly building giant rockets
One can only hope that the SpaceX employees tasked with bringing an already monumentally difficult idea from concept to reality are learning about these earth-shaking, “radical” decisions and changes through a medium other than Twitter. If those senior engineers and technicians are not extensively forewarned and given some say in these major system-wide decisions, it’s hard to exaggerate the amount of time, effort, and resources potentially being wasted (or at least misdirected).
There is undoubtedly something to be said for getting complex and difficult things as right as possible on the first serious try, especially when the sheer expense of the task at hand might mean that there is only one real chance to try. Still, it’s not particularly encouraging when a three-year-old hardware development program marked by several major design iterations is still experiencing anything close to “radical change”. After multiple years of concerted effort, BFR still appears to be in some sort of design limbo, where a constant and haphazard stream of on-paper changes act as a near-insurmountable hurdle standing in the way of a completed “good enough” blueprint that can begin to be made real.

Ultimately, even if some of the worst-case scenarios described above turn out to be true, there are still many, many reasons to remain positive about SpaceX’s BFR program on the whole. The next-gen rocket’s propulsion system of choice – an advanced engine known as Raptor – is quite mature at this point and may already be nearing initial flight readiness. Regardless of any future changes to BFR’s overall spaceship and booster structures, SpaceX technicians, engineers, and material scientists have likely gained invaluable experience in pursuit of an unprecedented 9-meter diameter rocket built almost entirely out of carbon fiber composites.
Further, it appears that quite a bit of progress has been made over the course of R&D programs related to methane-oxygen RCS thrusters (Falcon uses nitrogen), autogenous tank pressurization with gaseous methane and oxygen (Falcon uses helium), and perhaps even in-situ resource utilization (ISRU) that will be an absolute necessity to generate water, oxygen, and methane that will keep prospective Mars colonists alive and refuel spaceships for the voyage back to Earth.

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.
