SpaceX to attempt back-to-back Falcon Heavy launches with booster reuse in 2019
SpaceNews reports that SpaceX is planning an impressive duo of Falcon Heavy launches in the first half of 2019, the heavy lift rocket’s second and third missions. According to Nicky Fox, NASA’s heliophysics division director, SpaceX intends to recover and reuse all three Falcon Heavy first stage boosters for both launches and apparently believes that it can recover and prepare them for a second launch in as few as 60 days.
Following a highly successful February 2018 launch debut, SpaceX has targeted the launches of commercial satellite Arabsat 6A and the USAF’s Space Test Program 2 (STP-2) in the second half of 2018, a schedule that rapidly realigned to H1 2019. If the unofficial plan described above turns out to be true, the USAF will apparently become the first commercial customer to launch on a flight-proven Falcon Heavy.

A Reddit user was lucky enough to spot one of SpaceX’s next-gen Falcon Heavy side boosters – coincidentally just one day after Dr. Fox’s comments – on its way East through rainy Louisiana, undeniable evidence that the heavy lift rocket’s second (and third) launches have a real chance of happening in early 2019. According to Dr. Fox, SpaceX is seriously targeting a very rapid turnaround of Falcon Heavy’s next three first stage boosters, stating (admittedly without official confirmation) that SpaceX would be reusing the boosters from Arabsat 6A’s March 2019 launch on the planned April 2019 launch of STP-2.
“[Falcon Heavy] will launch [STP-2 in April] after the successful launch of Arabsat, which is currently manifested for March. [SpaceX] will recover and reuse the boosters, so we’re kind of watching what happens with that first launch.” – Dr. Nicky Fox via SpaceNews
Whether or not this officially unconfirmed information is correct, it certainly sounds like just the thing that CEO Elon Musk might challenge SpaceX to pull off, not to mention the fact that this would place the US Air Force in a situation requiring it to become the first commercial customer to launch on a flight-proven Falcon Heavy. This would be a truly dramatic change in attitude compared to comments made in just the last week, brought up in the context of SpaceX’s planned December 18 (now Dec 22) launch of the USAF’s first next-gen GPS satellite, GPS III SV01. In official comments provided to the media, the Air Force was extremely “uncertain” about allowing SpaceX to even attempt to recover its Falcon 9 booster, let alone allowing the company to fly Air Force payloads on flight-proven rockets.

Admittedly, the intentions behind STP-2 differ drastically from GPS III SV01. As the name suggests, the missions falls under a program explicitly designed to test and prove out new launch vehicles in the context of fast-tracking their certification for higher-value Air Force spacecraft. Falcon 9 could almost certainly launch STP-2 in a reusable configuration, but the USAF chose Falcon Heavy – and included literal dead weight – because the military branch is very interested in the rocket’s potential utility for more serious National Security Space missions.

SpaceX’s first Falcon Heavy launch famously featured flight-proven side boosters that performed jaw-dropping simultaneous landings at LZ-1 and LZ-2. Chances are good that Falcon Heavy Flight 2 and 3 will both feature additional attempts at simultaneous LZ booster landings. If SpaceX can find a way to launch Falcon Heavy twice in barely two months while still reusing all three first stage boosters, it’s hard to imagine a better way to demonstrate the economic and technological viability of both Falcon Heavy and Block 5’s reusability upgrades.

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.
