SpaceX’s second Falcon Heavy booster arrives in Florida as launch #2 closes in
SpaceX’s second Falcon Heavy side booster has made its way from Texas to Florida after completing a successful static fire acceptance test at the company’s McGregor complex, paving the way for the third and final booster – currently vertical on McGregor’s test stand – to complete its own round of tests and head East.
Once the third and most important booster – known as the center core – arrives at SpaceX’s Florida launch facilities, all three of the next Falcon Heavy’s boosters will be ready to head into the integration stage, culminating in an integrated static fire prior to the second launch ever of SpaceX’s flagship super-heavy-lift rocket.
A Texas pilot happened to fly by SpaceX’s McGregor facilities on January 11th, catching a live glimpse of a Merlin Vacuum (MVac) or second stage static fire test, as well a Falcon booster – perhaps Falcon Heavy’s next center core – vertical on the facility’s booster static fire stand. While it has not yet been visually confirmed as the next Falcon Heavy center core, a booster traveling through the Waco, Texas area to McGregor was spotted with protuberances that are not normally seen on regular Falcon 9 boosters and happened to be in the right place for FH-specific hardware.

There is also a case to be made that – per the fact that the first two side boosters have been built, shipped, tested, and delivered back-to-back – SpaceX chose to consecutively manufacture all hardware needed for the second Falcon Heavy instead of producing one or a few single-stick Falcon 9 boosters in between, which the appearance of a center core-like rocket in Texas certainly helps corroborate. While Falcon Heavy side boosters are effectively just Falcon 9 boosters with a few additional attachments and nose cones, currently scheduling indicates that SpaceX may attempt to rapidly turn all three Falcon Heavy Flight 2 boosters around perhaps just 30-60 days after their first launch. Otherwise, once the rocket’s 2019 launches have been completed, both side boosters can be converted back into Falcon 9 boosters and thus reenter SpaceX’s active fleet of flight-proven rockets.
Falcon Heavy’s center core, however, is dramatically different than a regular Falcon 9 booster, owing to the fact that it needs to essentially support triple the thrust and mechanical stresses as single-stick launches. The rocket’s design works to improve payload performance by using the two side cores to boost the center core and leave it with far more propellant left over than Falcon 9 would during a comparable launch profile, roughly equivalent to a three-person bike where only two people are pedaling hard. During a Falcon Heavy launch, side boosters thus separate a solid 30-60 seconds before the center core parts ways with the upper stage and payload.

Thanks to its significant differences, it’s highly unlikely – if not impossible – for a Falcon Heavy center core to launch a regular Falcon 9 mission. As such, once Falcon Heavy’s 2019 launches are completed, the center core will most likely be processed, refurbished, and then stored until the next Falcon Heavy payload is ready to go, at which point Falcon 9 boosters would be converted into Heavy side cores. Given that the Block 5 upgrade is designed to allow Falcon boosters to perform as many as 10 launches with minimal to no refurbishment and 100+ with regular repairs and maintenance, it’s entirely possible that a single Falcon Heavy center core could theoretically support all possible future launches of the rocket.
In reality, customers like the USAF and NASA will probably request new hardware for foreseeable Falcon Heavy launches, most of which would likely be extremely expensive flagship satellites (AFSPC-52) or interplanetary spacecraft (Europa Clipper).
Fans of @SpaceX will be interested to note that the government is now taking very seriously the possibility of flying Clipper on the Falcon Heavy.

Falcon Heavy’s next two launches are planned as early as March (a large communications satellite called Arabsat 6A) and April (an experimental USAF launch called STP-2 with two dozen separate payloads). With two side boosters already in Florida, those dates are now serious possibilities, and the center core’s arrival will be the telltale sign that Falcon Heavy’s second launch ever is imminent.

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.
