SpaceX ships Falcon 9 booster west for second California launch of 2019
A local resident spotted a SpaceX Falcon 9 booster heading west out of Florida, likely bound for the company’s SLC-4E Vandenberg Air Force Base (VAFB) launch pad and second California launch of 2019.
Barring a surprise reassignment, the booster Joshuah Murrah caught is Falcon 9 B1051, on its way west some 50 days after successfully supporting Crew Dragon’s March 2nd launch debut. Despite the availability of B1046, B1047, and B1049, B1051 was assigned to the Canadian Space Agency’s (CSA) Radarsat Constellation Mission (RCM) shortly after landing aboard OCISLY, triggering major launch delays. The most logical explanation for customer CSA’s and satellite contractor Maxar Technologies’ curious decision is that they must believe that Falcon 9 Block 5 boosters with more than one launch in their past add more risk than those that do not.
According to an April 16th update from CSA, RCM’s launch was scheduled for no earlier than (NET) late May or early June, although word on the ground is that mid-to-late June is now a more likely target. Contrary to rumors of delays, B1051’s shipment west indicates that SpaceX has more or less completed the booster’s refurbishment, likely the easiest Falcon 9 Block 5 refurbishment yet thanks to its relatively slow and cool reentry after launching Crew Dragon.
B1051 returned to Pad 39A’s integration hangar around March 7th, where it spent approximately 50 days being inspected, refurbished, and prepared for cross-country transport. The booster departed Florida on April 26th and will likely arrive at VAFB around May 2nd. Even assuming a slow trip west and buggy preflight preparations, Falcon 9 should theoretically be ready to launch RCM no later than the third or fourth week of May, barring issues or production delays with the mission’s fairing or Falcon upper stage.
Given that Maxar/CSA chose B1051 at a cost of months of launch delays, they may have needs that far outstretch the normal demands of SpaceX’s private (non-government) customers, not out of the question given that CSA is a national space agency and RCM is a high-value (~$1B) science mission. Short of flying on a new Falcon 9 booster, B1051 does theoretically seem to offer the least risk of failure insofar as one can claim that boosters that have completed more launches are more likely to fail.
SpaceX would likely vehemently deny such a claim given their position that highly reusable rockets – much like aircraft – will actually become more reliable and trustworthy the more they launch. Both positions make sense in theory but theory falls flat in the face of actual data, of which only SpaceX and certain customers have access to.
As an external observer, the best data available is a binary public record of Falcon 9 launch success, as well as the degree to which missions are delayed beyond their scheduled launch targets. Falcon 9 Block 5 boosters have launched 16 times in 11 months, six of which used a flight-proven first stage. Flight-proven boosters appear to be a bit more finicky than unflown rockets in terms of late-stage launch delays, but the data is inconsistent and the sample size statistically insignificant. More generally, Falcon 9 and Falcon Heavy have launched 72 times in nine years and suffered two total failures, both caused by unflown upper stages. In 72 launches, including 20 missions with flight-proven boosters, a Falcon 9/Heavy first stage has never caused a total mission failure.
In short, it’s impossible to intuit any clear performance or reliability advantage without the sort of granular per-mission data that only SpaceX and privileged customers have access to. In general, Falcon 9 – reused or not – has consecutively completed 41 successful launches since its second and last mission failure in September 2016, half (49%) of which used flight-proven boosters. Of course, customers have every right to their own standards and expectations of quality and risk-reduction, but Falcon 9’s performance largely speaks for itself at this point – anything beyond its default record of mission assurance is just icing on the proverbial spaceflight cake.

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.
