SpaceX skips Falcon 9 landing leg retraction on record-breaking booster
Four days after it returned to port, SpaceX quickly brought its latest recovered Falcon 9 booster horizontal, the last step before it can be transported back to one of SpaceX’s launch pad-adjacent processing facilities.
For unknown reasons, SpaceX skipped retracting its landing legs, but thanks to its recent reusability record, this particular Falcon 9 booster is now more important than ever.
On November 11th, Falcon 9 B1048 launched the 60-satellite Starlink-1 mission and became the first orbital-class SpaceX booster to fly on four separate missions. Preceded by Iridium-7 (July 2018), SAOCOM 1A (Oct 2018), and PSN-6/Nusantara Satu (Feb 2019), Starlink-1 was B1048’s (and SpaceX’s) heaviest payload ever, likely weighing around 17-18 metric tons (~39,000 lb).
Eight and a half days after Falcon 9 helped deliver all 60 satellites to an exceptionally low ~280 km (175 mi) parking orbit, all satellites have successfully deployed their solar arrays and powered on their electric thrusters, including the lone spacecraft SpaceX had concerns about prior to launch. That straggler came alive roughly 60 hours after its siblings but has since raised its orbit ~20 km, while the other 59 satellites have booster themselves by an average of 40 km (25 mi) or so.
At their current collective pace of ~5 km per day, all 60 satellites should reach their operational ~550 km (340 mi) orbits around the beginning of 2020.
Falcon 9 Block 5’s newest pathfinder
A bit less than nine minutes after its inaugural fourth launch, B1048 also became the first Falcon 9 booster to successfully land four times, coming to a halt near the center of drone ship Of Course I Still Love You (OCISLY). With its Port Canaveral processing nearly complete, B1048 now finds itself in a rare position.
As the first Falcon 9 Block 5 booster to fly four times, B1048 has first and foremost proven that the Block 5 design can be practically reused at least three times. However, the Block 5 upgrade is designed to support not just four – but at least ten – launches per booster, and SpaceX CEO Elon Musk has estimated that 100 or more launches may be achievable with more substantial routine maintenance. All this is to say that with B1048.4 safe and sound back on land, SpaceX technicians and engineers will likely pore over the booster to determine how exactly it has fared after four orbital-class launches, atmospheric reentries, and landings.
Stated a different way, B1048 is now the Block 5 upgrade’s pathfinder vehicle, meaning that it will in large part determine how SpaceX proceeds with its Falcon 9 reusability program. SpaceX has done this several times in the past – as long as the envelope is being pushed, and even if it’s not, there will always be ‘firsts’ to achieve, be it the first launch of a new rocket or the first launch of a thrice-flown booster. Prior to B1048, B1046 – also the first Falcon 9 Block 5 booster – was the pathfinder for reusability, becoming the first Block 5 booster to be reused for the first time and the second time (launch #3).
However, at the same time, Falcon 9 B1048.4 is arguably less important than it might seem. Perhaps the most useful data to be gained from the new pathfinder will involve comparing it to the likely extensively engineering data SpaceX has gathered from thrice-flown Falcon 9 boosters, including B1048 itself. Although still a fundamentally minuscule sample size in the scope of statistical significance, SpaceX has flown four (soon to be five) separate Falcon 9 boosters three times apiece.
By comparing B1048.4 to B1046.3, B1047.3, B1048.3, and B1049.3, SpaceX should be able to determine just how big the hurdle from a third launch to a fourth launch is compared to going from two launches to three launches. If the changes between those different reusability milestones are similar, it will be increasingly easy for SpaceX to rationally conclude that Falcon 9 Block 5 is fully capable of achieving its 10-flight design goal. If booster wear and tear appears to speed up from Launch 3 to 4 relative to Launch 2 to 3, design tweaks or additional refurbishment may be needed.
Most importantly, however, gathering new, high-fidelity data from flight experience like B1048’s fourth launch ultimately allows SpaceX to systematize post-flight inspections, helping technicians and engineers know where to look and what to watch out for when processing and refurbishing flight-proven boosters. The more boosters, launches, and landings there are, the more confident SpaceX can be that those systems and processes are sound.
For unknown reasons, SpaceX briefly attempted to retract Falcon 9 B1048.4’s landing legs on November 18th but abandoned retraction after a few attempts. On November 19th, technicians processed B1048 exceptionally quickly, removing its legs, breaking the booster over (rotating it to a horizontal position), and securing it on SpaceX’s transporter in barely half a day.
With recovery operations nearly complete, SpaceX can transport B1048 from Port Canaveral to Cape Canaveral, moving the booster to one of many processing and integration hangars for a thorough inspection and any necessary refurbishment. With any luck, B1048 will be ready for its fifth launch sooner than later, maybe allowing it to support SpaceX’s next dedicated Starlink launch.

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.
