SpaceX’s second Super Heavy booster might land in Mechazilla’s arms
CEO Elon Musk says that SpaceX could attempt to catch a Super Heavy booster out of mid-air with a tower-sized ‘Mechazilla’ robot as early as Starship’s second orbital launch attempt.
Speaking on Twitter just hours after SpaceX installed said Starship launch tower’s first arms, Musk has thankfully answered a question on the minds of many: how many prototype boosters must be expended? In a move that can be only described as unexpected, SpaceX revealed plans to fully expend its first orbital-class Starship and Super Heavy booster pair in May 2021 FCC filings, confirming (or strongly implying) that no true recovery attempts would be made.
Instead, in what could be described as a quasi-orbital debut, SpaceX intends to launch the first two-stage Starship to an altitude of around 200-300 km (TBD). Like many Falcon boosters, Super Heavy will separate a few minutes after liftoff, flip around, and boost back towards the South Texas coast, where it will attempt a soft landing 20 miles offshore in the Gulf of Mexico. Reading between the lines of Musk’s latest info, depending on the results of that ocean landing attempt, SpaceX might attempt to catch the second flightworthy Super Heavy booster on the very next launch.
Heading towards a similar fate, Starship will continue onwards and upwards like a Falcon upper stage. Based on its FCC application, SpaceX seems to have implied that Starship will stop just short of true orbit – traveling slow enough to passively reenter Earth’s atmosphere before completing a full trip around the planet. Of course, it’s possible that SpaceX simply left out plans for an intentional deorbit burn, but it does make sense that the company might try to lock in safeguards for such an ambitious inaugural test flight.
In other words, if Starship were to fail during the ~80 minutes it would spend coasting in space, its launch trajectory design would more or less passively prevent a Russian roulette scenario reminiscent of China’s recent spate of uncontrolled reentries. The feats facing Super Heavy are thankfully a fair bit simpler, though Starship booster recovery does pose its own hurdles.
In an apparent effort to reduce risk, SpaceX intends to fully expend the first flightworthy Super Heavy (potentially Booster 4) and all 29 of its Raptor engines. There will be no attempt at all to land the booster or its one-of-a-kind engines at land or on a sea-based platform – partly because Elon Musk appears to have endeavored to entirely prevent the installation – and, perhaps, the design and assembly – of legs. Instead, in one of the eccentric executive’s less intuitive gambles as of late, SpaceX will entirely dispense of more than half a decade of experience landing 90+ Falcon boosters on legs to attempt to catch Super Heavy boosters out of the air with house-sized arms tacked onto a 145m (~475 ft) tall tower.
No different than a hypothetical landing with legs, Super Heavy will still have to boost back to land, coast, and fire up several Raptor engines for a final landing burn – only on tiny handle-like hardpoints and giant moving arms instead of legs and a concrete pad. If catching boosters eventually proves reliable enough to be a worthwhile reinvention of the wheel, the only apparent benefit of the approach will be a slight reduction in Super Heavy’s dry mass.
According to Musk, though, SpaceX might not have to wait long to find out just how viable a recovery method ‘Mechazilla’ really is and will “hopefully” attempt to catch Super Heavy Booster 5 (B5) after Starship’s second orbital launch attempt. Presumably, that attempt is contingent upon FAA approval and on Booster 4 successfully simulating a smooth, accurate landing in the Gulf, as even a minor issue during a catch attempt could catastrophically damage pad hardware that would take months to repair or replace.
For now, it’s almost impossible to say when Starship S20 and Super Heavy B4 will be ready for their orbital launch debut, as that now lies almost solely in the hands of the FAA. In theory, the FAA could complete environmental reviews and grant SpaceX a launch license as few as two or so months from now. In practice, SpaceX could be forced to sit and wait for at least 6-12 more months. Regardless, SpaceX has already begun assembling and staging sections of Ship 21 and Booster 5, so the company could be ready for an extremely rapid turnaround (and Mechazilla’s first catch attempt) after Starship’s orbital launch debut – whenever that may come.

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.
