SpaceX set for Falcon Heavy triple booster landing, hottest center core reentry yet

Falcon Heavy center core B1055 successfully landed aboard drone ship OCISLY after a record-breaking reentry. Here's to hoping that B1057 can repeat the feat. ? (SpaceX)

SpaceX’s third Falcon Heavy launch is ready to wow crowds once more with a synchronized side booster landing at Cape Canaveral and a center core recovery attempt more than 1200 km (750 mi) off the coast of Florida.

Based on the fact that Falcon Heavy’s STP-2 center core (B1057) is set to smash SpaceX’s current record for drone ship downrange distance, chances are good that B1057 will separate from the upper stage and payload traveling faster and higher than any recoverable Falcon booster before it. In short, the fresh Block 5 booster will likely be subjected to the most extreme (hottest) atmospheric reentry a SpaceX booster has ever experienced before a serious recover attempt. Thankfully, the earliest the booster can be expected to fly again is H2 2020, giving SpaceX at least a full year for a cautious, careful refurbishment.

Weather and rocket pending, Falcon Heavy Flight 3 will lift off with the Department of Defense’s (DoD) Space Test Program-2 (STP-2) mission as early as 8:30 pm PDT (11:30 pm EDT, 03:30 UTC) on June 24th. Around 2.5 minutes after liftoff, both side boosters will deploy from the center core/upper stage stack, flip around, and burn hard to entirely cancel out their eastbound momentum, picking up speed as they head back to the Florida coast.

After a leisurely 6-minute coast and reentry burn, the booster pair are set to land at SpaceX’s Landing Zones 1 and 2 roughly 8.5 minutes after launch. Pictured below (with the same boosters, no less), B1052 and B1053 will hopefully replicate the simultaneous landings that followed their picture-perfect April 11th launch debut. Despite being the first flight-proven SpaceX boosters to launch as part of a US military mission (STP-2), both boosters will also simultaneously tie SpaceX’s current record for Block 5 booster turnaround (74 days), although the company’s overall record (71 days) still stands.

Meanwhile, STP-2’s fresh Falcon Heavy Block 5 center core – B1057 – will still be soaring above Earth at hypersonic speeds and high altitudes after its side booster companions have successfully come to a rest. Incredibly, the booster’s absolutely critical reentry burn – used to quite literally cushion the blow and minimize reentry heating with the rocket’s engine exhaust – will start at T+8:53 after liftoff. A full 2.5 minutes later (T+11:21), center core B1057 will attempt to land aboard drone ship Of Course I Still Love You, stationed ~1240 km (750 mi) off the coast of Florida.

For reference, Falcon Heavy Flight 2’s Block 5 center core landed aboard OCISLY around T+9:50 after launch, meaning that STP-2’s center core will be in the air – sans any sort of boostback or altitude-raising burn – for a solid 90 extra seconds – 15% longer. To get that extra flight time, B1057 will have to be traveling significantly faster and reach a much higher altitude than its predecessor. In short, B1057 will likely experience the most intense reentry conditions a Falcon booster has ever been subjected to. The current record-holder, B1055, separated from the upper stage and payload 100 km (62 mi) above the Atlantic while traveling nearly ~3 km/s (1.9 mi/s, Mach 8.8).

Falcon Heavy center core B1055 gently landed aboard drone ship OCISLY after its record-breaking recovery. With any luck, B1057 will be similarly successful but will be spared the fate of toppling over at sea. (SpaceX)

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles

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

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.
