Update #2: SpaceX has successfully delivered Starlink 4-4 – batch of 52 new satellites – to low Earth orbit (LEO), completing the first of three back-to-back Falcon 9 launches scheduled less than three days apart.
Starlink 4-4 marks the 98th successful Falcon landing, the first time SpaceX has performed a non-polar Starlink launch from its West Coast pad, and the first time a Falcon 9 booster has completed 11 orbital-class launches and spaceflights. Up next, SpaceX is scheduled to launch Turkey’s Turksat 5B geostationary communications satellite out of its Cape Canaveral, Florida LC-40 pad. Falcon 9 could lift off as early as 10:58 pm EDT, Saturday, December 18th (03:58 UTC 19 Dec) – just 15 hours after Starlink 4-4. Set in September 2021, SpaceX’s current record is two launches in ~44 hours.
Update: SpaceX’s second dedicated West Coast Starlink launch has slipped to no earlier than (NET) 1:24 am PDT (09:24 UTC) on Saturday, December 18th. Headed to an orbit unusual for a Vandenberg Space Force Base launch, Starlink 4-4 could now lift off just 18 hours before a different SpaceX mission – Turksat 5B – lifts off from the opposite side of the country.
Barring delays to Cargo Dragon’s CRS-24 space station resupply mission, which remains scheduled for 5:06 am EDT on December 21st, that means that SpaceX is now on track to launch three Falcon 9 rockets in three days (less than 73 hours).
SpaceX appears to be on track to round out a record-breaking year with three Falcon 9 launches in four days.
With the diverse trio of missions, SpaceX will orbit another batch of laser-linked Starlink satellites, deliver a large communications satellite to geostationary transfer orbit (GTO), send a Dragon to space for sixth time this year, and break at least two company records. The first mission, known as Starlink 2-3, could occur as early as the morning of December 17th, kicking off an incredibly busy period of launches – and not just for SpaceX.
Starlink 2-3
Referring to the fact that the mission will be the third launch for the second distinct group or ‘shell’ of Starlink satellites, Starlink 2-3 will actually be the second dedicated launch to a semi-polar orbit, leapfrogging Starlink 2-2 for unknown reasons after Starlink 2-1’s successful September launch. Originally scheduled to launch in mid-October, SpaceX was forced to stand down just a few days before liftoff for unknown reasons and at least a week or two of delays soon put Starlink 2-3 at risk of clashing with the company’s upcoming NASA DART launch, which unsurprisingly took precedence. SpaceX successfully launched the Double Asteroid Redirection Test (DART) mission on November 24th.
Late on December 13th, tugboat Scorpius likely departed Port of Long Beach with SpaceX drone ship Of Course I Still Love You (OCISLY) in tow – a fairly airtight confirmation that a SpaceX launch is just a handful of days away. Based on safety Notices to Airmen and Mariners (NOTAMs/NOTMARs), Starlink 2-3 is scheduled to launch sometime between 12am and 6am PDT (UTC-8) on Friday, December 17th. If accurate and SpaceX stays on schedule, Falcon 9 could lift off from the company’s Vandenberg SLC-4E launch pad with Starlink 2-3 in tow just 22 days after a different Falcon 9 rocket launched DART – smashing the pad’s current 36-day turnaround record by almost 40%.
Aside from drastically increasing the maximum theoretical launch cadence SpaceX’s West Coast pad is capable of supporting, Starlink 2-3 is also expected – as it was in October – to fly on Falcon 9 booster B1051, potentially making the mission the first time a liquid rocket booster has completed eleven orbital-class launches. B1051 debuted in March 2019, sending an uncrewed Crew Dragon on its way to orbit for the first time. Before SpaceX’s Starlink launch cadence fell off a cliff in the second half of 2021, B1051 completed its tenth launch on May 9th, 2021, averaging one launch every ~80 days over a two-year career. Starlink 2-3 will be B1051’s first launch in 7 months and eleventh launch in 33 months.
Turksat 5B
As early as 11:58 pm EDT (UTC-5) on Saturday, December 18th, another Falcon 9 rocket is scheduled to launch Turkey’s Turksat 5B geostationary communications satellite from SpaceX’s Cape Canaveral LC-40 pad. There’s a good chance that former Falcon Heavy booster B1052 – recently converted into a Falcon 9 after more than two years in storage – will be assigned to the mission, which is set to be SpaceX’s 30th orbital launch in 2021.
CRS-24 and more!
Finally, a different Falcon 9 (possibly B1062 or even a new booster entirely) is scheduled to launch a new Cargo Dragon 2 spacecraft on CRS-24 – potentially the company’s 23rd operational International Space Station (ISS) resupply run since October 2012. It will be Falcon 9’s sixth Dragon launch of 2021 – another record for SpaceX and the spacecraft. If the schedule holds, CRS-24 could lift off as early as 5:06 am EDT (UTC-5) on Tuesday, December 21st and would be SpaceX’s third Falcon 9 launch in roughly 100 hours (a little over four days). CRS-24 is expected to be SpaceX’s 31st and final launch of 2021, beating out the 26-launch record it set just last year.
However, the rest of the world isn’t quite finished. As early as the day after CRS-24, an Ariane 5 rocket is scheduled to launch the almost $10 billion, NASA-built James Webb Space Telescope (JWST). Decades in the making, JWST will be the single most expensive payload and the largest space telescope ever launched and is functionally irreplaceable and hard (but not impossible, if the political will is there) to repair, making it perhaps the most universally nerve-wracking uncrewed launch in the history of spaceflight.

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.
