SpaceX CEO Elon Musk teases Mars breakthroughs as Starship design radically changes
During an interview with Axios, SpaceX CEO Elon Musk noted that he was “[really fired up about] a number of breakthroughs [SpaceX had recently made]” while being asked about his thoughts on the likelihood of him personally going to Mars (“70%”).
The minute-long teaser did not go much deeper but it certainly raises a number of questions (and hints at explanations) for a rapid-fire series of contradictory developments and changes to SpaceX’s BFR – since renamed to “Starship” and “Super Heavy” – per a series of tweets from Musk over the last two weeks.
In a typical Muskian fashion, when Axios interviewers asked, “What is the likelihood that you personally will go to Mars?”, the CEO responded with an exact percentage – 70% – without skipping a beat. Musk also fervently and rather eloquently refuted the popular and harebrained idea that any SpaceX-enabled Mars colony would simply become “an escape hatch for the rich”. If the rich wanted Mars or lunar bases as “escape hatches”, there are dozens of multibillionaires that could singlehandedly fund Musk’s estimated $2-10B price tag for the completion of the entire BFR development program while still retaining 50-90% of their net worth.
Musk’s retort is worth reading in full.
Mike Allen: “[Mars] could be an escape hatch for rich people.”
Elon Musk: “No! Your probability of dying on Mars is much higher than earth. Really the ad for going to Mars would be like Shackleton’s ad for going to the Antarctic. It’s gonna be hard. There’s a good chance of death, going in a little can through deep space. You might land successfully. Once you land successfully, you’ll be working nonstop to build the base. So, you know, not much time for leisure, and once you get there, even after doing all this, it’s a very harsh environment, so there’s a good chance you die there. We think you can come back but we’re not sure. Now, does that sound like an escape hatch for rich people?”
Back to BFR
While thoroughly entertaining, the most interesting aspect of this one-minute teaser was the approximate two seconds where Musk suggested that SpaceX had recently made several major breakthroughs in the context of BFR and Mars. What exactly those breakthroughs could be is entirely unclear, but the fact that Musk seemed positive about the recent developments and spoke of “breakthroughs” at all feels like an encouraging sign that the last two weeks of Musk’s chaotic announcements, updates, and abrupt cancellations are less indicative of program instability than they initially seemed to be.
Most notably, Musk appeared to announce and then completely cancel a sort of mini-spaceship that SpaceX was to base off of Falcon 9’s upper stage as a BFR spaceship technology demonstrator in less than two weeks. If realized, that mini-BFS would have reentered Earth’s atmosphere at orbital velocities to flight-test hypersonic fins and a new “ultra light” heat shield that will be (or would have been) critical for the overall success of BFS/Starship.
Contour remains approx same, but fundamental materials change to airframe, tanks & heatshield

Ironically, in the middle of writing this article, Musk tweeted specifically about “fundamental” changes to the spaceship, leaving little more than the general appearance and propulsion systems unchanged. In essence, the design of BFS/Starship is now almost unrecognizable when compared with past iterations, at least from a perspective of the ship’s most critical systems.If Starship will not be built out of composites, then it’s possible that the multiple years SpaceX engineers and technicians have spent trying to develop large carbon composite propellant tanks (2016-present) and the time, energy, and capital put into those efforts will be almost entirely for naught if BFR pivots away from composite tanks.

By all appearances, dozens of employees have spent the last year accepting delivery of $10-50M worth of custom-built composite tooling, setting it up, and building giant composite tank domes and segments. If composite tanks are no longer planned for the booster or spaceship, all that work may have been for nothing. Needless to say, we could certainly do for Musk’s proposed Reddit AMA – if not an entirely new BFR update event – to shed some light on the machinations behind these earthshaking programmatic changes.

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.
