SpaceX rocket boosters line up in port for the first time after back-to-back launches
For the first time ever, two SpaceX Falcon 9 boosters – fresh off of two successful Starlink launches and landings – have met back at Port Canaveral, creating the first rocket ‘traffic jam’ of its kind.
On March 11th, Falcon 9 booster B1058 stuck its sixth launch and landing after supporting SpaceX’s sixth dedicated Starlink launch (Starlink-20) this year. 74 hours later, a separate Falcon 9 rocket lifted off from SpaceX’s second East Coast launch pad, successfully sending another batch of 60 Starlink satellites (Starlink-21) on their way to orbit. For its role in the mission, booster B1051 became the first Falcon first stage to launch and land nine times – just one shy of a ten-flight rocket reusability goal SpaceX has been chasing for years.
Now, aside from setting the new standard for Falcon reusability, placing 120 satellites into orbit in three days, and breaking SpaceX’s record for the shortest turnaround between two East Coast launches, the back-to-back Starlink launches have left both Falcon 9 boosters in the right place and right time to cross paths as they prepare for future flights.
As SpaceX began to ramp up its orbital launch cadence – largely thanks to Starlink – throughout 2020, it become clear that the company would eventually start to find new pressure points as it pushed its fleet of reusable rockets and their recovery assets to new limits. In 2021, that intentional exertion of stress across the broader SpaceX launch ‘pipeline’ has become even clearer.
A mere 10 weeks into 2021, SpaceX has already completed eight orbital launches, averaging one mission every nine days or 40 launches per year if extrapolated through the end of 2021. Just two days prior to Falcon 9 booster B1058’s arrival back at Port Canaveral after its successful Starlink-20 launch, Falcon 9 booster B1049 – last tasked with launching Starlink-17 on March 4th – wrapped up its port processing and was transported by road back to Cape Canaveral Air Force Station (CCAFS) or Kennedy Space Center (KSC) to prepare for its ninth flight.
At that point, it became clear it was just a matter of time before two boosters would simultaneously occupy SpaceX’s Port Canaveral berths. Two days later, record-breaking Falcon 9 booster B1051 arrived back in port and was greeted by booster B1058 – legs retracted, standing vertical, and waiting to be ‘broken over’ (brought horizontal) for transport.
It’s hard to imagine a better or (pardon the buzzword) more synergistic pair of boosters to appear in port together. On their separate launch debuts, Falcon 9 B1051 supported Crew Dragon’s spectacularly flawless uncrewed launch debut, while Falcon 9 B1058 became the first private rocket in history to launch US astronauts 14 months later. Known as Demo-1 and Demo-2, those two missions collectively mark arguably the most significant milestone in the history of modern US spaceflight, ending a decade-long period where the US was unable to launch its own astronauts.
Just a week after the rocket’s 2019 Demo-1 launch debut, Falcon 9 B1051 is SpaceX’s new booster fleet ‘life leader’ (the most-flown rocket) after averaging one launch ever 11 weeks for the last two years. Aside from supporting Cargo Dragon 2’s launch debut last December, Falcon 9 B1058 has flown six times, averaging an even more impressive one launch every eight weeks. Together, the two boosters have aced 15 orbital-class launches roughly 190 metric tons of satellites and Dragon spacecraft into orbit in their two-year career, significantly more than the maximum payload of Saturn V – the largest rocket to successfully launch.
Falcon 9 B1051 could reportedly fly for the tenth time as early as April 2021.

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.
