SpaceX’s first flight-proven Starship takes another step towards reuse
Nine days after becoming the first full-size prototype to survive a high-altitude launch and landing, SpaceX has installed Starship SN15 at the second of two identical launch mounts to prepare for potential reuse.
On May 5th, after a week or two of several minor delays, Starship SN15 – the fifth full-size prototype of its kind – lifted off from SpaceX’s Boca Chica, Texas launch pad under the thrust of three Raptor engines. Like all four of its predecessors, the 50-meter-tall (165 ft) steel rocket easily ascended to an apogee greater than 10 km (6.2 mi), shutting down one Raptor every ~90 seconds to its keep velocity low. When the final engine cut off, SN15 arced over onto its belly and free-fell to around half a kilometer above the ground, using four hollow steel ‘flaps’ to control its orientation like a skydiver’s limbs.
The most radical maneuver came around six minutes after liftoff when the sideways Starship reignited two or three of its Raptors, aggressively flipped into a nose-up position, deployed six stubby landing legs, and gently touched down a few hundred feet east of the stand it took off from.
Despite a fairly large fire that burned for several minutes after touchdown, SpaceX ultimately found itself – for the first time ever – with a full-size Starship prototype that survived its inaugural ~10-km launch and landing. A careful process of safing and securing then followed as operators commanded (or monitored) SN15 to disarm explosive flight termination system (FTS) charges, vent any remaining propellant, and eventually depressurize its fuel and oxygen tanks.
Unlike Starhopper, SN5, and SN6 – which also survived flights – SpaceX was apparently able to safe SN15 without any real issues and recovery teams were able to approach the rocket within a few hours of landing instead of the 12-24+ hours that were normal prior. SpaceX also debuted a sort of supersized version of the ‘Octagrabber’ robots that remotely secure Falcon boosters after drone ship landings, allowing the recovery team to secure Starship SN15 to a stable platform and transporter without a crane.
No longer at risk of toppling over, Starship SN15 then… sat where it landed. Less than two days after touchdown, CEO Elon Musk unexpectedly revealed that SpaceX “might try to refly SN15 soon,” indicating that initial post-flight inspections had revealed that the first flight-proven three-engine Starship was in excellent condition. SN15 would ultimately spend another four days (six total) sitting on a transporter at the landing zone. On May 11th, SpaceX rolled Starship SN15 from its landing spot to “Pad B” – the second of two identical suborbital launch mounts.
Perhaps due to stormy weather and high wind gusts in the area, SN15 once again sat still – this time for another three days. Ultimately, the Starship prototype was rapidly lifted onto Pad B’s launch mount, secured, and detached from the crane in a matter of hours of May 14th – possibly the smoothest pad installation yet. In the two days since then, SpaceX has begun more in-depth inspections that will ultimately determine whether the first flight-proven Starship is truly fit for a second launch.
That process likely wont take more than a few days and even if SN15 isn’t deemed (re)flightworthy, there’s still a very good chance SpaceX will put the Starship through some kind of test(s) before it’s retired. Stay tuned for more details likely to come this week.

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.
