Update: SpaceX says it and NASA are moving forward with plans to launch a Crew Dragon carrying US, Japanese, and Russian astronauts as early as noon EDT (16:00 UTC) on Wednesday, October 5th.

Concurring with a statement made on October 3rd, SpaceX has also called off a planned October 4th launch of its Starlink 4-29 mission. However, the company has delayed Starlink 4-29 just 24 hours and says that Falcon 9 will launch the latest batch of internet satellites out of California no earlier than (NET) 4:10 pm PDT (23:10 UTC) on October 5th. Intelsat has also confirmed that its Galaxy 33 and Galaxy 34 geostationary communications satellites are scheduled to launch on a Falcon 9 rocket as early as 7:07 pm EDT (23:07 UTC) on October 6th, leaving SpaceX on track to launch three Falcon 9 rockets from three launch pads in 31 hours.

The company achieved a similar feat earlier this year when it launched three Falcon 9 rockets in 36 hours. Three launches in 31 hours would break that record.

SpaceX is on the cusp of launching three Falcon 9 rockets in a handful of days. Minor issues with two of the three missions, however, have complicated the already hard process of coordinating so many launches at the same time.

For many reasons, rocket launches are an inherently difficult thing to schedule, and that difficulty only gets magnified when attempting to launch rockets as quickly as possible for customers with very different needs while using a fixed number of launch pads. SpaceX’s upcoming series of launches demonstrates the slippery nature of high-cadence rocket launch scheduling better than most.

Last month, SpaceX ran into issues (mainly bad weather) that delayed its Starlink 4-34, 4-35, and 4-36 missions by varying degrees. Before those delays, SpaceX had intended to break its LC-40 pad turnaround record with Starlink 4-35 and then repeat the feat with Starlink 4-36, but that opportunity closed when Starlink 4-34’s several weather delays pushed Starlink 4-35 from September 19th to the 24th and raised the risk of the next launch, Starlink 4-36, interfering with customer missions planned in the first half of October.

That burst of customer missions, all of which take priority over SpaceX’s own Starlink missions, meant that a few-day delay for a mission two launches prior ultimately pushed Starlink 4-36 from the end of September to no earlier than October 20th. It will launch out of Cape Canaveral Space Force Station’s (CCSFS) LC-40, the same pad that launched Starlink 4-35 on September 24th and will launch Intelsat’s Galaxy 33 and 34 satellites no earlier than (NET) October 6th and Eutelsat’s Hotbird 13F satellite NET October 13th. All four launches (including Starlink 4-36) are thus contingent upon each other, so a delay with one mission would likely delay each subsequent mission to leave enough time for pad turnaround and rocket processing.

SpaceX isn’t the only company that launches out of Cape Canaveral, Florida. Originally scheduled in late September, the United Launch Alliance’s (ULA) Atlas V launch of the SES-20 and SES-21 geostationary communication satellites was delayed by the same weather system that indirectly hampered Starlink 4-35 and 4-36. That mission is now set to launch NET 5:36 pm EDT (21:36 UTC) on October 4th.

Up first, however, is SpaceX’s Starlink 4-29 mission out of California’s Vandenberg Space Force Base (VSFB). Delayed to October 4th hours before its October 3rd target, the new schedule will give SpaceX “more time for pre-launch checkouts,” Falcon 9 will now lift off as early as 4:48 pm PDT (23:48 UTC), a little over two hours after Atlas V. However, making the whole situation even more interlinked, SpaceX says it will stand down from its October 4th Starlink launch attempt if its next Florida mission – Crew Dragon’s fifth operational NASA astronaut launch – remains on track for its current noon EDT (16:00 UTC), October 5th launch target.

In an October 3rd briefing following a mostly clean launch readiness review (LRR), NASA and SpaceX officials revealed that three new minor issues – “not showstoppers” – had appeared after a busy period of ground testing. An otherwise successful astronaut dry dress rehearsal and a subsequent wet dress rehearsal and static fire uncovered a possible fire extinguisher leak in the Dragon spacecraft and a minor issue with one of the Falcon 9 rocket booster’s nine Merlin 1D engines. A communications issue was also discovered on the SpaceX drone ship Crew-5’s rocket booster is meant to land on in the Atlantic Ocean.

SpaceX and NASA officials weren’t especially worried about the issues and were confident they would be resolved in time for an October 5th launch. If they aren’t and Crew-5 slips to October 6th, SpaceX should be able to launch Starlink 4-29 on October 4th, but then it’s unclear if the company will also be able to launch Intelsat’s Galaxy 33 and Galaxy 34 geostationary communications satellites on the same day as Crew-5. Galaxy 33/34 is scheduled to launch NET 7:07 pm EDT on October 6th, likely ~6 hours after Crew-5’s own October 6th launch window.

If Crew-5 slips and Galaxy 33/34 can’t launch on the same day, it would likely delay both Hotbird 13F and Starlink 4-36. It’s also unclear if Starlink 4-29 can launch on the same day as Crew-5 if it flies after Dragon. Either way, SpaceX could potentially end up launching Crew-5, Galaxy 33/34, and Starlink 4-29 on October 5th and 6th – potentially less than a day and a half apart.

As SpaceX continues to push the limits of what is possible with its existing Falcon launch and landing infrastructure, chaotic scheduling situations like this, where small issues impact large strings of launches, will become the norm instead of the exception

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.

Recent commentary on social media has highlighted what could very well prove to be The Boring Company’s real disruption.

The analysis was shared by tech watcher Aakash Gupta on social media platform X, where he argued that the real story behind the tunneling startup’s Nashville tunnel project is the company’s targeted $25 million per mile construction cost.

According to Gupta’s breakdown, Nashville’s 2018 light rail proposal was priced at roughly $200 million per mile. New York’s East Side Access project reportedly cost about $3.5 billion per mile, while Los Angeles Metro expansion projects have approached $1 billion per mile.

By comparison, The Boring Company has stated it can construct 13 miles of twin tunnels in the Music City Loop for between $240 million and $300 million total. That implies a cost near $25 million per mile, or roughly a 95% reduction from industry averages cited in the post.

Several technical departures from conventional tunneling allow the Boring Company to lower its costs, from its smaller 12-foot diameter tunnels to its fully electric Prufrock machines that are designed to mine continuously with no personnel inside the tunnel and their capability to “porpoise” for easy launch and retrieval.

Tesla and Space CEO Elon Musk responded to the post on X, stating simply that “Tunnels are so underrated.”

The Boring Company has seen some momentum as of late, with the company recently signing a construction contract in Dubai and the Universal Orlando Loop progressing. Recent reports have also pointed to tunnels potentially being constructed to solve traffic congestion issues near the Giga Nevada area. 

While The Boring Company’s tunnels have so far been used for Loop systems publicly for now, Elon Musk recently noted that the tunneling startup’s underground passages would not be limited only to ride-hailing vehicles.

In a reply to a post on X which discussed the specifications of the Music City Loop, Musk clarified that “any fully autonomous electric cars can use the tunnels.” This suggests that vehicles potentially running systems like FSD Supervised, even if they are not Teslas, could be used in systems like the Music City Loop in the future.
