ULA set to ship Vulcan rocket to Florida for Moon lander launch
After many years of delays, all the parts of the United Launch Alliance’s next-generation Vulcan Centaur rocket are about to converge on Florida for their first launch.
Unveiled in 2015, ULA has been working on Vulcan Centaur since at least 2014. Following Russia’s first illegal invasion of Ukraine, countries around the world attempted to punish the aggressor mainly through economic sanctions. In the US, those sanctions included bans on the import of most Russian aerospace technologies, including the RD-180 engines that still power ULA’s Atlas V workhorse rocket in 2023. In 2014, ULA announced that it would work with Blue Origin to integrate the startup’s BE-4 engine into a new rocket booster to end its reliance on Russian engines.
More than eight years later, that BE-4 engine is finally ready for flight, and the rest of the first two-stage Vulcan rocket appears to be right behind it.

Eastward-bound
In a burst of New Year activity, CEO Tory Bruno confirmed that Vulcan Flight 1’s core stage (booster) has been fully assembled, buttoned up, and loaded onto ULA’s transport ship. The aptly named RocketShip will ferry the booster from ULA’s Decatur, Alabama factory to Cape Canaveral, Florida, where it will enter the final stages of launch preparation at the company’s Cape Canaveral Space Force Station (CCSFS) LC-41 pad.
Simultaneously, ULA has finished proof testing Vulcan’s first Centaur V upper stage, a larger and more advanced version of the Centaur III stage ULA and its predecessors have been flying for decades. Centaur V is almost twice as wide as Centaur III and is designed to hold two and a half times more propellant, enabling significantly higher performance in some scenarios.
Additionally, while ULA has partially abandoned plans for a reusable upper stage called ACES (Advanced Cryogenic Evolved Stage), some of those improvements may still be added to Centaur V. Compared to Centaur III, Centaur V’s longevity in space will grow from 8 to 12 hours. ULA is also developing a “mission extension kit” that will allow it to operate for multiple months – unprecedented for a rocket stage powered by cryogenic propellant.

Photos taken by a local paper appear to indicate that ULA is shipping one or more payload fairing (nosecone) halves alongside Vulcan’s first flightworthy booster. While unconfirmed, it would make sense for ULA to ship Vulcan’s booster and fairing together. Another tweet from Tory Bruno indicates that ULA intends to ship Vulcan’s booster and upper stage together, increasing the odds that all components will be aboard RocketShip when it departs for Florida.
A New Workhorse
Vulcan Centaur is ultimately designed to fully replace ULA’s existing Delta IV and Atlas V rockets. Building and operating two very different rockets simultaneously is undoubtedly one of the reasons that ULA’s launch costs are so much higher than SpaceX’s, and simplifying to a single production line is one clear way to achieve major cost savings. ULA hopes that the simplest version of Vulcan will eventually cost about $100 million per launch – still far more than SpaceX’s base Falcon 9 price [PDF] but potentially more competitive than Atlas V. That’s unclear, though, as Bruno has previously stated that Atlas V’s launch costs have fallen to about $100 million apiece thanks to unrelated cost savings.
Regardless, Vulcan Centaur will be a capable rocket and its price is close enough to SpaceX’s extremely competitive Falcon 9 for it to be a mostly valid option for launch customers who want diversity or want to avoid SpaceX for less rational reasons. Vulcan has secured more than 70 launch contracts thanks to ULA’s intimate relationship with the US military and Amazon’s reluctance to launch its Project Kuiper internet satellites with the company behind Starlink, a direct competitor.


Fitted with two BE-4 engines, six solid rocket boosters (SRBs), and unknown upgrades, ULA says the most capable version of Vulcan Centaur will be able to launch up to 12.1 tons (26,700 lb) to the Moon, 15.3 tons (33,700 lb) to geostationary transfer orbit (GTO), and 27.2 tons (60,000 lb) to low Earth orbit (LEO). To high orbits, the most capable Vulcan variant will fairly competitive with SpaceX’s Falcon Heavy rocket. To low orbits, it will generally match or slightly exceed the performance of an expendable Falcon 9, but likely for a much higher price. By every measure, the simplest and cheapest Vulcan variant is significantly less capable than even a partially reusable Falcon 9 and will likely cost 50-100% more.
Moon or bust
Indicating ULA’s confidence in the unflown rocket, the main target of Vulcan’s first launch is the Moon. Vulcan Flight 1 will carry two main payloads: the first two Amazon Kuiper satellite prototypes and Pittsburgh startup Astrobotic’s first Peregrine Moon lander. After deploying both Kuiper satellites in low Earth orbit, Centaur V will fire up again and attempt to send the 1.3-ton (~2850 lb) Peregrine lander directly to the Moon – also known as a trans-lunar injection (TLI) burn. Developed as part of NASA’s Commercial Lunar Payload Services (CLPS) program, Peregrine will be tasked with entering orbit around the Moon and eventually landing up to 70-90 kilograms (150-200 lb) of payload on the lunar surface.
The first Peregrine Moon lander is fully assembled and currently in the middle of extensive integrated testing. If successful, ULA CEO Tory Bruno says that Vulcan will likely be ready to launch sometime in Q1 2023, though Q2 2023 is more likely.

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.
