SpaceX Falcon 9 “fleet leader” returns to port after record reuse
SpaceX is well and truly 70% of the way to a longstanding rocket reusability target after successfully launching and landing the same Falcon 9 booster on seven orbital-class missions.
Known as Falcon 9 B1049, the record-breaking rocket booster and new “fleet leader” safely returned to Port Canaveral aboard drone ship Of Course I Still Love You (OCISLY) on Saturday, November 28th. Aside from a minor hiccup and 24-hour delay from a vague need for “additional mission assurance,” Falcon 9’s seventh-flight debut was as flawless as ever, simultaneously marking the rocket’s 100th launch overall and 99th success after a decade of operation.
Crystallized in May 2018 and floated many times before by CEO Elon Musk in years prior, SpaceX’s primary goal for Falcon 9 reusability has been ten flights per booster with near-zero refurbishment between launches for several years. As such, Falcon 9 B1049’s latest success means that SpaceX is just three flights away from crossing that partly symbolic but still spectacular milestone.
For as long as SpaceX and Musk have been transparent about their desire to implement reusability into orbital-class rockets, entrenched competitors like Arianespace and United Launch Alliance (ULA) have almost continuously responded with vague internal studies that conclude that changing their ways is counterproductive. Often, somewhat arbitrary figures arise, with ULA executives frequently falling back on the excuse that SpaceX-style reusability only makes financial sense if a booster fleet averages at least ten flights each.
Arianespace executives have echoed similar sentiments over the years and more recently implied that it would only ever make sense to invest in SpaceX-style reusability if the conglomerate could guarantee at least 30 launch contracts annually.
Instead of complaining and splitting theoretical hairs for the better part of a decade, SpaceX simply started working. After many tries, the first successful Falcon 9 booster landing came in December 2015. ~15 months later, SpaceX reused an orbital-class rocket booster on a commercial mission for the first time ever. Another 14 months after that, Falcon 9 Block 5 debuted with a bevy of upgrades focused on reusability and reliability, and that same Falcon 9 booster became the first to launch on three orbital-class missions just seven months later.
Falcon 9 B1049 debuted in September 2018. 26 months later, the rocket has completed its seventh successful launch and landing, averaging one orbital satellite launch every ~110 days – an impressive feat for the fourth Block 5 booster ever built. Newer boosters like Falcon 9 B1058 are already improving on the records of their predecessors, managing an average of one launch every 60-80 days.
Even if ten flights were to inexplicably become a permanent design limit for all Falcon operations, SpaceX’s current fleet of eight flight-proven Falcon 9 boosters would still be capable of singlehandedly supporting at least 54 more launches, with another 16 on top of that if two dormant Falcon Heavy side boosters are converted for single-core use. SpaceX is unlikely to stop producing Falcon boosters for at least another year or two, adding at least 6-10 more first stages to the fleet to support dozens of crucial Falcon 9 and Falcon Heavy launches over the next 5-10 years.
In simpler terms, it’s almost time for SpaceX’s competitors to move their goalposts again. If B1049 can mirror its 2020 average of one launch every ~80 days, the Falcon 9 booster could be ready for its tenth flight as early as Q3 2021 (with B1051 not far behind it).

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.
