(Update: Sunday) SpaceX’s high-altitude Starship launch debut slips to Monday
Update #2: Per new Temporary Flight Restrictions, there’s now a chance that SpaceX has rescheduled Starship’s (now slightly less) high-altitude launch debut on Sunday afternoon, December 6th.
As always with experimental testing, uncertainty remains. Stay tuned for updates as we close in on Starship SN8’s 12.5-kilometer (~7.8 mi) launch debut.
Update: SpaceX’s high-altitude Starship launch debut appears to have slipped to no earlier than (NET) Monday morning, December 7th, and been reduced from 15 km to 12.5 km.
FAA-approved flight restrictions filed on December 2nd were retracted on December 3rd for unknown reasons, ultimately giving SpaceX several more days to prepare Starship SN8 for an ambitious high-altitude launch, coast, freefall, and landing attempt.
Meanwhile, SpaceX has also lowered Starship SN8’s apogee target to 12.5 km (7.8 mi) from 15 km, itself a reduction from 20 km made earlier this year. Why is entirely unclear but it’s likely that the company is in active discussion (and probably arguments) with the FAA, perhaps requiring a compromise to ensure regulatory approval.
It remains to be seen if SpaceX will perform any additional testing over the weekend or if the company will attempt to schedule Starship SN8’s launch debut on Saturday or Sunday. Stay tuned for updates and Elon Musk’s promised SpaceX webcast.
SpaceX has received FAA approval to attempt Starship’s high-altitude launch debut as early as Friday according to a Temporary Flight Restriction (TFR) filed on December 2nd.
SpaceX’s first high-altitude Starship TFR revealed that the crucial flight test is now scheduled sometime between 8 am and 5 pm CST (14:00-23:00 UTC) on Friday, December 4th, with identical backup windows available (and cleared with the FAA) on Saturday and Sunday. Originally scheduled as early as November 30th, the delays are less than surprising given the complexity and unprecedented nature of the flight test facing SpaceX.
Starship serial/ship number 8 (SN8) – the first functional full-height prototype – is tasked with launching from Boca Chica, Texas to an apogee of 15 kilometers (~9.5 miles) and dropping back to Earth to test an unproven approach to rocket recovery.
Often referred to as a bellyflop or skydiver-style attitude, Starship SN8 will attempt to freefall belly-down back to earth, using four large flaps to maintain a stable approach much like skydivers use their arms and legs to control heading and speed. When landing on planets or moons with relatively thick atmospheres, a controlled freefall could save Starship a huge amount of structural mass (no need for wings or actual airfoils) and propellant – a major benefit for what aims to be the largest reusable orbital spacecraft ever built.
Powered by three Raptor engines capable of producing up to 600 metric tons (1.3 million lbf) of thrust at full throttle, SN8’s launch debut will mark Starship’s first multiengine flight – a major milestone for any rocket prototype. SpaceX CEO Elon Musk also recently noted that Starship SN8’s propellant tanks will only be “slightly filled” for its 15 km launch debut, potentially resulting in an extremely healthy thrust to weight ratio at liftoff.
Based on several unofficial estimates, Starship SN8 is also likely to break the sound barrier on ascent, potentially putting the prototype through conditions similar to what an actual orbital launch might see at Max Q (the point of maximum aerodynamic pressure). Further adding to the daunting list of ‘firsts’, SN8’s 15 km debut will be the first Starship hop or flight with a nosecone, making it the first full-scale structural test of a nose section and the methods used to attach it to Starship’s tank section. It’s hard to exaggerate the number of things that could go wrong and the number of ways Starship SN8 could fail during its first flight.
In the interim, SpaceX has taken Starship’s launch delay as an opportunity to perform some kind of additional testing on the evening of December 2nd, involving some kind of cryogenic proof test (using liquid nitrogen) or wet dress rehearsal (WDR; using real liquid methane and oxygen). While there were initial signs that SpaceX would put SN8 through one or several more Raptor static fires before clearing the rocket for flight, it appears that those plans were cancelled earlier this week.
Less testing amplifies the risk that Starship SN8 will fail after liftoff, the probability of which Musk has pegged at ~67%. Regardless, SN8’s launch debut is bound to be spectacular and Starships SN9 and SN10 are nearly ready to take over wherever SN8 leaves off.

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 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.
