SpaceX has completed its 52nd successful Falcon 9 launch in 52 weeks, sustaining an average cadence of one launch per week for a full 12 months.

Simultaneously, the Starlink 4-2 rideshare mission set a new record for Falcon 9 booster reuse, marked SpaceX’s 150th consecutively successful launch, and was one of the most complex commercial launches it has ever performed.

In addition to 34 new Starlink V1.5 satellites that joined almost 3000 other working SpaceX spacecraft in orbit, Starlink 4-2 deployed the company’s largest rideshare payload yet – AST SpaceMobile’s 1.5-ton (~3300 lb) BlueWalker 3 communications satellite.

Falcon 9 lifted off on schedule with the combined 12-ton (~26,500 lb) payload safely secured inside its composite payload fairing at 9:20 pm EDT (01:20 UTC) on Saturday, September 10th. Tasked with lifting the rocket’s expendable upper stage, recoverable fairing, and payload most of the way out of Earth’s atmosphere was Falcon 9 booster B1058, a nine-engine first stage that debuted by launching two NASA astronauts in May 2020.

28 months later, B1058 lifted off with Starlink 4-2 and BlueWalker 3 on its 14th spaceflight and orbital-class launch, breaking Falcon 9’s booster reuse record. The rocket performed no differently than it had every time previously, burning for a bit less than three minutes before deploying the upper stage and returning to Earth. About nine minutes after liftoff, B1058 safely touched down on drone ship A Shortfall Of Gravitas (ASOG), likely setting the booster up to break its own record before the end of 2022. With 13 launches already under their belts, boosters B1051 and B1060 will likely follow B1058 past the same 14-flight milestone in the near future.

Once free from the booster, Falcon 9’s expendable upper stage kicked off SpaceX’s most complex commercial launch ever. Measuring about six minutes long, the first and longest burn brought the second stage and payload into an elliptical orbit a few hundred kilometers above Earth’s surface. A second burn followed about 45 minutes after liftoff, raising the low end of that ellipse to deploy BlueWalker 3 into a circular orbit around 500 kilometers (~310 mi). Using a massive antenna, AST SpaceMobile’s first large satellite prototype will eventually attempt to directly communicate with mobile phones to provide a level of connectivity equivalent to 5G/LTE – all from space.

Once free of its rideshare payload, the focus shifted to Starlink. In theory, SpaceX could have taken the easy way out and significantly simplified the mission by deploying all 34 satellites at the same altitude as BlueWalker 3, simultaneously allowing them to reach their operational 540-kilometer (~336 mi) orbits in days instead of months. Instead, SpaceX pursued an exceptionally complex mission requiring five burns from Falcon 9’s upper stage.

After deploying BlueWalker 3, Falcon 9 S2 lowered one end of its orbit at around T+67 minutes, followed by a fourth burn to lower the other end almost two hours after liftoff. The upper stage then spun up end over end and eventually released all 34 Starlink satellites at an altitude of ~335 kilometers (~208 mi), where debris and faulty satellites will take days – rather than years – to reenter Earth’s atmosphere and burn up.

While SpaceX doesn’t confirm post-payload operations, Falcon 9 S2 was also scheduled to perform a fifth and final burn to quickly deorbit itself, ensuring that the mission only produced five pieces of benign debris. At their very low orbits, those five pieces (four ‘tensioning rods’ and the BlueWalker 3 payload adapter) will pose next to no threat to other spacecraft or rockets and should reenter within a few weeks.

Starlink 4-2 was SpaceX’s 52nd successful Falcon 9 launch since September 14th, 2021, meaning that the company has technically already achieved CEO Elon Musk’s goal of 52 launches in one year – albeit not a calendar year. Perhaps even more impressive, the mission was SpaceX’s 150th consecutively successful Falcon launch. No other single rocket (Falcon 9) or rocket family (Falcon) has launched more times in a row without failure.

Finally, Starlink 4-2 was SpaceX’s 42nd launch of 2022. If the company continues its average cadence over the last three months, it could end 2022 having completed more than 60 Falcon launches in one calendar year.

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 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.
