SpaceX aims for a burst of December launches despite recent delays
Originally scheduled to launch on December 4, SpaceX’s thirteenth resupply mission to the International Space Station (ISS) has been pushed back to no earlier than Friday, December 15 after routine preflight checks identified potential contaminants in the Falcon 9 launch vehicle’s upper stage fuel lines.
The past six weeks have been something of an outlier in an otherwise relentless series of 2017 launches for SpaceX. In early November, defects in payload fairings were discovered at the company’s Hawthorne, CA factory and quickly traced to the Zuma mission’s fairing, at that point already vertical and prepared to launch from Kennedy Space Center. SpaceX chose to pause its launch indefinitely as it investigated the fairings already delivered to its several launch pads and began the process of either repairing or replacing those impacted. The CRS-13 Cargo Dragon mission soon took precedent as Zuma remained on hold.

Although CRS-13 does not require a payload fairing and was thus unaffected by SpaceX’s ongoing investigation, the mission was scheduled to be launched from Launch Complex-40, essentially a new pad after ten months of extensive repairs and upgrades. This translated into a few days of additional delays as the SpaceX launch crew thoroughly tested the pad’s new systems and pushed towards static fire of the flight proven Falcon 9 booster, successfully completed on December 6 after an additional handful of days of pad-related delays. This pushed the launch date from the 4th to the 8th, then the 12th and the 13th to accommodate further limited testing in order to ensure pad readiness. However, routine tests revealed a possible fuel line contamination in Falcon 9’s second stage, and SpaceX delayed the mission an additional 48 hours to resolve the problem. CRS-13 is now aiming for launch no earlier than 7:35am/10:35am PST/EST on December 15, but the window is instantaneous and any additional delays would push the launch into late December, at which point Cape Canaveral Air Force Station returns to operational status with the conclusion of winter holidays.
Although LC-40 suffered through its own teething period of bugs and testing while returning to life, there is a certain irony in the fact that a bug in the only wholly new component of CRS-13’s Falcon 9 rocket has been the most recent cause of delay; both the Falcon 9 booster and Cargo Dragon capsule are refurbished, flight-proven hardware, although both the trunk and heat shield of the Dragon were likely replaced with new components. There is something to be said about the logical nature of truly “flight-proven” hardware being more trustworthy than completely new alternatives, but it is far more likely that the upper stage contamination can be largely traced back to the new pad hardware.

Although Teslarati’s launch photographer Tom Cross has been battered about by Zuma and CRS-13 delays, SpaceX has demonstrated an admirable level of patience and caution, risking significant delays to their launch manifest in order to best ensure the safety and reliability of their launch services. While delays are painful in the spaceflight fan business, they are impermanent and secondary to safety and success. SpaceX will undoubtedly return to their regular programming in no time at all, with the West-coast launch of Iridium-4 and first pad rollout of Falcon Heavy up next on the docket. Stay tuned!

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.
