SpaceX’s Mr. Steven preparing for first Falcon 9 fairing catch attempt in months
SpaceX recovery vessel Mr. Steven has spent the last several weeks undergoing major refits – including a new net and arms – and testing the upgraded hardware in anticipation of the vessel’s first fairing catch attempt in more than four months.
Required after a mysterious anomaly saw Mr. Steven return to Port in February sans two arms and a net, the appearance of a new net and arms guarantees that SpaceX is still pursuing its current method of fairing recovery. Above all else, successfully closing the loop and catching fairings could help SpaceX dramatically ramp its launch cadence and lower costs, especially critical for the affordable launch of the company’s own Starlink satellite constellation.
The Saga of Steven
For a few months of 2019, it was entirely conceivable that SpaceX had all but given up on catching Falcon fairings, having spent the better part of 2018 without a single success during both post-launch and experimentally controlled catch attempts. Admittedly, a year may feel like a huge amount of time, but SpaceX has demonstrated just how hard the reliably successful recovery of orbital-class rocket hardware really is.
Depending on how one examines the history of Falcon 9, it took SpaceX anywhere from ~30 and ~70 months and either 7 or 9 failed recovery attempts before the first Falcon 9 booster successfully landed in December 2015. Excluding helicopter-based fairing drop tests, Mr. Steven and SpaceX’s fairing recovery team have made five attempts to catch fairings in the vessel’s net after Falcon 9 launches. All have been unsuccessful, with the closest miss reportedly landing in the Pacific Ocean just 50 meters away from Mr. Steven’s massive net.
In January 2019, Mr. Steven sailed ~8000 km (5000 mi) from Port of Los Angeles to Port Canaveral, passing through the Panama Canal. For unknown reasons, during a trip out to sea to catch a Falcon 9 fairing in February, Mr. Steven abruptly turned around early and arrived in port missing two of four arms, four of eight booms, and the entirety of its custom net. The remaining arms/booms were removed and the vessel spent roughly three months docked with just a handful of excursions.
In late May, technicians rapidly installed new arms and booms, as well as a new (and blue) net, bringing about the end of months of inactivity. Mr. Steven has yet to venture beyond the safety of Port Canaveral since its new ‘catcher’s mitt’ was installed, but SpaceX has been testing the new setup by repeatedly lowering a Falcon fairing half into the net. It’s too early to raise expectations but it seems plausible that the iconic recovery vessel will be ready to attempt its first fairing catch in ~4 months as part of Falcon Heavy’s next scheduled launch, currently NET June 22.
A challenger approaches…
Although Mr. Steven’s prospects look better than they have in months, SpaceX’s fairing recovery engineers and technicians have not been sitting on their hands. Begun as a check against the growing possibility that reliably catching fairings in a (relatively) small net is just too difficult to be worth it, SpaceX has been analyzing methods of reusing fairings without Mr. Steven. Most notably, despite the failure to catch fairings out of the air, the fairing halves themselves – relying on GPS-guided parafoils – have proven to be capable of reliably performing gentle landings on the ocean surface.
This consistently leaves the fairings intact and floating on the ocean but at the cost of partial saltwater immersion and exposure to surface-level sea spray and waves. At least in today’s era of highly complex large satellites, customers typically demand that payload fairings (like Falcon 9’s) offer a clean room-quality environment once the satellite is encapsulated inside. Sea water is full of salt, organic molecules, and water, all three of which do not get along well with extremely sensitive electronics. The whole purpose of recovering and reusing fairings is to make their reuse more efficient and less expensive than simply building a new fairing. The task of cleaning composite structures to clean room-standards after salt water exposure and immersion tends to be less than friendly to both aspirations.
According to SpaceX CEO Elon Musk, however, that challenge may be distinctly solvable and could even be easier than the Mr. Steven approach. After Falcon Heavy’s commercial Arabsat 6A launch debut in April 2019, Musk again confirmed that SpaceX would be ready to test that alternate method of fairing reuse very soon and plans to do so on an “internal” (i.e. Starlink) launch later this year. As noted below, this is helped by the fact that SpaceX’s internally-developed Starlink satellites apparently have no need for the acoustic insulation panels that normally protect sensitive spacecraft from the brutal acoustic environment produced by rockets while still in Earth’s atmosphere.
For fairing reusability, the lack of those panels is just one less thing to have to worry about cleaning or replacing. Intriguingly, it’s easy to imagine that – much like SpaceX has apparently designed Starlink satellites to be resistant to intense acoustic environments – the company could have also required that they be tough enough to tolerate a less-than-pristine fairing environment. With that approach, SpaceX could continue to build new fairings for every customer launch, entirely amortizing their production cost before transferring the ‘dirty’, flight-proven fairings to internal Starlink launches.
In essence, SpaceX’s customers would quite literally be paying the company to build the very Falcon 9 boosters and fairings it will ultimately use to launch its massive Starlink constellation, requiring hundreds of launches over the next decade. The faster and more efficiently SpaceX can build and launch Starlink, the faster it can develop Starship/Super Heavy and entirely transcend any concerns of salty fairings (let alone expendable upper stages). But in the meantime, Mr. Steven will return to his catching duties and SpaceX will continue to attempt to reuse payload fairings.

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.
