SpaceX Falcon rocket aces 100th consecutive rocket landing
SpaceX has successfully launched its first batch of next-generation Starlink V2 satellites, likely kicking off a new era of affordability for the constellation.
Simultaneously, demonstrating just how far SpaceX is ahead of its competitors and the rest of the spacefaring world, the Starlink 6-1 launch culminated in the 100th consecutively successful landing of a Falcon rocket booster. As a result, SpaceX’s landing reliability now rivals the launch reliability of some of the most reliable rockets ever flown. That extraordinary feat bodes well for SpaceX’s next-generation Starship rocket, which is designed to propulsively land humans on the Earth, Moon, Mars, and beyond.

SpaceX’s landing reliability milestone is made all the more impressive by the lack of immediate competition. More than seven years after SpaceX’s first successful Falcon 9 booster landing and six years after the company’s first successful Falcon booster reuse, Falcon 9 and Falcon Heavy are still the only reusable orbital-class rockets in operation.
Blue Origin has had some success reusing the first stage of its suborbital New Shepard rocket. Rocket Lab has also recovered small Electron rocket boosters from the ocean, but it’s yet to catch a booster with a helicopter – a necessity for cost-effective reuse. Many other companies have announced or begun developing their own partially or fully-reusable rockets. But even in a best-case scenario, the most promising of those potentially competitive rockets are still a year or two from their first launch attempts, let alone their first successful recoveries and reuses.
SpaceX debuted the Falcon 9 rocket behind most of its successful booster recoveries and reuses in June 2010. SpaceX recovered a Falcon 9 booster for the first time in December 2015 and reused a (different) booster for the first time in March 2017. It completed nearly all of that risky development work during launches for paying customers.
Even after the first success, many unsuccessful landing attempts followed as SpaceX pushed the performance envelope and discovered new failure modes. Falcon’s most recent landing failure occurred during a Starlink launch in February 2021 and was caused by a hole in a flexible ‘skirt’ meant to keep Earth’s superheated atmosphere out of the flight-proven booster’s engine section.
However, every landing since Falcon 9’s Starlink-19 landing failure has been successful. On February 27th, 2023, almost exactly two years after that failure, Falcon 9 booster B1076 touched down on one of SpaceX’s three drone ships, marking the rocket family’s 100th consecutively successful landing. Starlink 6-1 was also the Falcon family’s 183rd consecutively successful launch, as a Falcon landing failure has never prevented the completion of a mission’s primary objective.
Launch-wise, Falcon 9 and the Falcon family have already become the most statistically reliable rockets in history. Very few rockets in history have managed 100 consecutively successful launches, let alone landings. For example, according to spaceflight reporter Alejandro Romera, the next most reliable American rocket – the McDonnell Douglas Delta II – narrowly achieved 100 consecutively successful launches before its retirement in 2018. The landing reliability of SpaceX’s Falcon rockets is thus tied with the launch reliability of the most reliable American rocket not built by SpaceX.
Additionally, SpaceX Falcon booster landings are now statistically more reliable than the launches of United Launch Alliance’s much-touted Atlas V rocket, which has (more or less) successfully launched 97 times.
Falcon’s landing reliability is an encouraging sign for SpaceX’s next-generation Starship rocket. For Starship to fully achieve SpaceX’s goals, it will eventually need to be able to propulsively land humans on Earth and at other destinations throughout the solar system. SpaceX currently has no plans no plans to develop an independent crew escape system for Starship, meaning that the rocket itself will instead have to demonstrate extraordinary overall reliability. SpaceX executives have stated that Starship will only be deemed safe enough to launch humans once it has completed “hundreds” of successful launches and, presumably, landings.
Falcon has managed 100 successful landings in a row despite large gaps in redundancy. Most landing burns are conducted with a single Merlin 1D engine. Any issue with that engine would likely result in a failed landing. Falcon boosters also have four landing legs and four grid fins powered by a single hydraulic pump. The failure of that pump or one of four legs have demonstrably doomed earlier landings.
Starship’s much larger size and excess performance could provide a larger margin for error and allow for more redundancy. But Falcon has demonstrated that that even a rocket with multiple glaring single-points-of-failure can achieve 100 consecutively successful landings.

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.
