SpaceX’s Mr Steven just misses catch, returns with intact Falcon 9 fairing

Published

on

SpaceX appears to have successfully retrieved both halves of a Falcon 9 payload fairing intact, despite failing to catch them with recovery vessel Mr Steven.

Near the end of the company’s Iridium-6/GRACE-FO launch webcast, SpaceX engineer John Insprucker said that Falcon 9’s two payload fairing halves had both successfully deployed their parachutes and landed in the Pacific Ocean, also stating that Mr Steven “came very close” to success in an attempt to catch a fairing half in an upgraded net. The vessel’s return to port confirmed this, showing both fairing halves on board Mr Steven’s long utility deck, apparently intact and in great condition aside from saltwater immersion.

Per SpaceX VP of Mission Assurance Hans Koenigsmann, anything more than incidental exposure to sea spray appears to preempt any attempt at fairing reuse, meaning that perfectly intact fairing halves recovered from the surface of the ocean are incapable of flying on future commercial Falcon 9 missions. While he did not go into detail, it’s probable that SpaceX’s inability to reuse ocean-retrieved fairings derives from the extremely clean environments satellites are designed to survive in. Before reaching the vacuum of space, arguably the ‘cleanest’ environment that exists, satellite payloads (be it cameras, antennae, solar panels, can be generalized as extraordinarily sensitive collections of electronics and sensors that remain in clean-room environments throughout their time on Earth. This extends to the environment inside the payload fairing, and cleaning a fairing from seawater organics, particulate matter, and the general risk of outgassing would likely be so expensive and tedious that it would run counter to SpaceX’s goal of lowering the cost of launch with reusability.

Although they cannot be operationally reused, these and past halves presumably have been or will be invaluable as hardware pathfinders, assisting engineers and technicians in their pursuit of ultra-precise, reliable landings in Mr Steven’s net.

Mr Steven, a shiny new Fast Supply Vessel, has been extensively modified by SpaceX in its role as recovery vessel, most notably including massive claw-arms and a large, yellow net intended to allow the boat to catch parasailing payload fairings just before they impact the ocean surface. This requires an impressive level of accuracy and precision, given the fact that SpaceX’s payload fairings are typically traveling more than two kilometers per second at a peak at altitude of anywhere from 100-200 kilometers (functionally in space) at the point of separation, while Mr Steven’s net (the landing target) is at least a magnitude smaller than even SpaceX’s drone ships. With that in mind, it should come as little surprise that SpaceX has required ten or more failed attempts to get to the point where they are confident that a fairing half can successfully be captured in Mr Steven’s net.

 

Given how close SpaceX apparently was this time around, it’s all but inevitable that one of the next two or three California launches will feature the first truly successful fairing catch, paving the way for routine reuse of the ~800 kg, $3m halves. SpaceX’s next launches from Vandenberg Air Force Base are tentatively scheduled for the first half of July, late September, and October.

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

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.
