SpaceX’s spectacular USSF-67 Falcon Heavy launch in photos
On January 15th, SpaceX’s Falcon Heavy rocket lifted off for the second time in 75 days to launch another batch of US military payloads into orbits tens of thousands of kilometers above Earth’s surface.
Six and a half hours later, the US Space Systems Command (SSC) confirmed that Falcon Heavy had again completed the exceptionally difficult launch without issue. To deliver the USSF-67 mission’s payloads directly to geosynchronous orbit (GSO), the giant SpaceX rocket had to sacrifice one of its potentially reusable boosters and complete a complex six-hour ballet of rolls, burns, and spacecraft deployments. And for the second time in a row, Falcon Heavy did so without apparent issue.
In an SSC press release [PDF], Maj. Gen. Stephen Purdy, program executive officer for Assured Access to Space, said that the group “had another fantastic launch today on a Falcon Heavy.” He added that “while the launch itself was impressive,” he was “most proud of the fact that we placed important [national] capabilities into space.” And an impressive launch it certainly was.

A Falcon (Heavy) spectacle
As previously discussed, USSF-67 was Falcon Heavy’s first twilight launch. The extraordinary cadence of SpaceX’s workhorse Falcon 9 rocket, which Falcon Heavy is derived from, caused twilight launches and the incredible light shows they can produce to become a fairly routine phenomena. But just under five years after its February 2018 debut, there had still never been a Falcon Heavy launch ‘jellyfish’ or ‘nebula.’ That thankfully changed on Sunday.
The rocket lifted off just ten or so minutes after sunset and soared into the fading purple skies. Those skies were still relatively bright at ground-level, reducing the amount of contrast, but the resulting light show was still spectacular as Falcon Heavy and its immense exhaust plume ascended back into the sunlight. The artificial sunrise lit up that pillar-like plume with the colors of sunrise and, eventually, bright daylight.
Close-up views enabled by tracking telescopes captured the true drama, which began shortly after Falcon Heavy’s twin side boosters separated from the rocket’s main core stage and upper stage, flipped around, and ignited their engines to fly back to the Florida coast they’d only just lifted off from. As the nine-engine center core continued towards space, each booster fired up one and then three Merlin 1D engines for their boostback burns.
A view from Astronomy Live captured the moment of boostback burn ignition, during which the side boosters visibly blasted ‘craters’ the Falcon Heavy center core’s much more powerful plume. As those plumes interacted, the fluid dynamics and light produced by multiple Merlin 1D engines combined to create chaotic whisps of orange, red, and yellow – akin to an exploding nebula. The moments prior were also spectacular as the two side boosters, lit up by direct sunlight against the nearly black sky, began gently floating away from the center core and spinning around with bursts from several nitrogen gas thrusters – a brief moment of serenity before the violence of engine ignition.
On a chariot of fire
But as Maj. Gen. Purdy noted, the purpose of USSF-67 – spectacle aside – was to carry a number of important payloads into orbit.
“After both side boosters touched down, SpaceX ended its live coverage at the request of the Space Force, reiterating the mission’s secretive customer and nature. The USSF hasn’t confirmed much about the USSF-67 mission’s payloads, but Falcon Heavy is known to be carrying a geostationary communications relay satellite called CBAS-2 and likely built by Boeing. CBAS-2 is joined by Northrop Grumman’s third Long Duration Propulsive EELV or LDPE-3A, a combination of a propulsive kick stage and a satellite. LDPE-3A is carrying a collection of rideshare satellites and payloads and is designed to operate for months in orbit. Using USSF-44 as a guide, the total USSF-67 payload could weigh roughly 3.75 to 4.75 tons (8,250-10,500 lb).”

The same SSC press release provides more detail, noting that LDPE-3A carries two hosted payloads – Catcher and WASSAT. Catcher is a space weather instrument developed by the Aerospace Corporation, while WASSAT is a prototype [PDF] of a wide-angle observation instrument designed to track other satellites in GSO. LDPE is also hosting “three payloads developed by the Space Rapid Capabilities Office (SRCO),” including “two operational prototypes for enhanced situational awareness, and an operational prototype crypto/interface encryption payload providing secure space-to-ground communications capability.”
Two down, one to go
For Falcon Heavy side boosters B1064 and B1065, both of which supported USSF-44 and USSF-67, their missions are far from over. Their second successful side-by-side landing has cleared the boosters to be reused on a third US military launch called USSF-52. Originally known as AFSPC-52, the mission was Falcon Heavy’s first operational US military launch contract and the first time the rocket beat competitor United Launch Alliance (ULA) during a competitive procurement.
Next Spaceflight reports that USSF-52 is scheduled to launch no earlier than April 10th, 2023, less than three months from now. Once that mission is complete, Falcon Heavy will have no more US military missions on contract, although more will almost certainly be rewarded sooner than later. USSF-52 is sandwiched between two other Falcon Heavy launches. Next Spaceflight also reports that Falcon Heavy could launch the ViaSat-3 communications satellite as early as March 2023 and the Jupiter-3 (EchoStar 24) communications satellite as early as May 2023, making for a busy 90 days.
For that trio to happen as scheduled, SpaceX will have to beat Falcon Heavy’s record 75-day turnaround, which has coincidentally (?) occurred twice: first between Arabsat 6A and STP-2, and again between USSF-44 and USSF-67. Including USSF-67, SpaceX has up to five Falcon Heavy launches scheduled this year.

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.
