SpaceX delays Starlink launch as ocean outmatches drone ship upgrades
SpaceX’s 13th Starlink launch has been indefinitely delayed by “severe weather in the recovery area, later explained by CEO Elon Musk as case of the drone ship losing its battle with the ocean.
Originally scheduled to launch as early as September 17th, Starlink-12 – the 12th Starlink v1.0 mission – was pushed to September 18th about an hour before liftoff. SpaceX didn’t offer a reason then but is now reporting that weather in the recovery zone (Atlantic Ocean) was to blame for the 24-hour recycle and the indefinite launch delay that followed soon after.
CEO Elon Musk went further, revealing that the SpaceX drone ship assigned to Starlink-12 was unable to hold its position in strong Atlantic Ocean currents, forcing the company to delay the mission indefinitely. Until conditions improve in SpaceX’s drone ship recovery zone, the company will likely be unable to launch Starlink missions. Musk, however, already has a solution in mind.

Current was too strong for droneship to hold station. Thrusters to be upgraded for future missions.— Elon Musk (@elonmusk) September 18, 2020
In the same tweet, Musk revealed that SpaceX means for its drone ship “thrusters to be upgraded for future missions,” an obviously intuitive response to drone ships being overpowered by ocean currents. There’s one simple problem, though: drone ship Just Read The Instructions, the same ship currently unable to hold its position in (admittedly strong) ocean currents, completed extensive upgrades just a handful of months ago.


Prior to those upgrades, JRTI and OCISLY were effectively identical – both sporting a few modest generators and four relatively small station-keeping thrusters (bright blue). After more than half a year of work, drone ship JRTI came out the other end with dramatically larger azimuth thruster pods and at least several times the power output. The space beyond drone ship JRTI’s booster landing deck has been more or less filled to the brim with new generators.
In other words, short of some major structural changes or a smaller landing area for Falcon boosters, it’s hard to imagine how SpaceX could substantially upgrade Just Read The Instructions’ already-upgraded generators and thrusters.

In drone ship JRTI’s defense, the Eastern seaboard is still feeling the remnants of Hurricane Sally at the same time as Hurricane Teddy is just a few days away. Just ~48 hours from now, Starlink-12’s Falcon 9 booster landing zone will be subject to 30-40 mph (50-70 km/h) winds and peak wave heights of 15 feet (~4.5m) in the shadow of Teddy. The seas in that region will likely remain untenable for booster landings until September 24th or 25th at the earliest without major changes in current forecasts.
Current climate models don’t necessarily predict an increase in the frequency of Atlantic Ocean hurricanes as a result of global warming, although warming will very likely boost the intensity of most hurricanes to a major degree. As such, it’s a bit of a wash whether investing heavily in dramatic drone ship performance upgrades would actually be worth it for Falcon booster recovery, given that the tropical storm season only lasts a fraction of the year. If SpaceX wants to consistently launch 50-100+ times per year out of Florida, it’s likely a no-brainer.

Regardless, if SpaceX does pursue upgrades far beyond Just Read The Instructions’ current setup, it will be fascinating to see what the company’s two workhorse drone ships end up looking like. If current forecasts hold, Starlink-12 is unlikely to launch until late next week, a delay that has pushed Starlink-13 (previously NET late September) into October.

Tesla gathers Cybercab fleet in Gigafactory Texas
Images and video of the Cybercab fleet were shared by longtime Giga Texas observer Joe Tegtmeyer in posts on social media platform X.
Tesla appears to be assembling a growing number of Cybercabs at Gigafactory Texas as preparations continue for the vehicle’s mass production. Recent footage shared online has shown over 30 Cybercabs being transported by trucks or staged near testing areas at the facility.
The images and video were shared by longtime Giga Texas observer and drone operator Joe Tegtmeyer in posts on social media platform X.
Interestingly enough, Tegtmeyer noted that many of the Cybercabs being loaded onto transport trucks were still equipped with steering wheels. This suggests that the vehicles are likely testing units rather than the final driverless configuration expected for the company’s Robotaxi service.
The vehicles could potentially be headed to testing sites across the United States as Tesla prepares to expand its Robotaxi fleet.
Additional footage captured at Gigafactory Texas also showed the Cybercab’s side and rear camera washer system operating as vehicles were being loaded onto transport trucks.
The growing number of Cybercabs at Giga Texas comes amidst the company’s announcement that the first production Cybercab has been produced at the facility. Full Cybercab production is expected to begin in April.
The vehicle is expected to play a central role in Tesla’s Robotaxi ambitions as the company looks to expand autonomous ride-hailing operations beyond its early deployments using Model Y vehicles.
Tesla has also linked Cybercab production to its proposed Unboxed manufacturing process, which assembles large vehicle modules separately before integrating them. The approach is intended to reduce production costs and accelerate output.
Musk has also noted that the Cybercab’s ramp will likely begin slowly due to the number of new components and manufacturing steps involved. However, he stated that once the process matures, Cybercab production could scale quickly.

Elon Musk’s xAI, creator of Grok and Grokipedia, celebrates its third birthday
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
Elon Musk’s artificial intelligence startup xAI has marked its third anniversary. The update was shared in a post from the xAI Memphis account on social media platform X.
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
As per xAI, it has built three massive data centers in the city, launched a coherent cluster of 330,000 GBs, created over 3,000 jobs, and paid over $30 million in taxes to local communities.
xAI’s Memphis operation has become a key part of the company’s infrastructure as the company works to train and deploy its Grok artificial intelligence models. Elon Musk has been quite optimistic about Grok’s potential, noting in the past that the large language model might have a shot at achieving artificial general intelligence (AGI).
xAI’s Memphis’ crown jewel is its Colossus supercomputer cluster. The project was announced in 2024 and has since become the home of one of the world’s largest AI compute facilities. The first phase of Colossus reached its initial 100,000 GPU operational milestone in just 122 days, or just about four months.
Industry figures such as Nvidia CEO Jensen Huang have praised the facility, noting that projects of similar scale typically take two to four years to complete.
xAI has cited Memphis’ central location, skilled workforce, and industrial infrastructure as key reasons for selecting the city as the home of its AI training operations. The company has also emphasized plans to expand the site further as it scales compute capacity for Grok and future AI models.

Tesla Sweden’s Megapack Supercharger near Arlanda continues to aggravate IF Metall union
The charging site, located in Arlandastad outside Stockholm, appears to be operating despite ongoing union blockade measures tied to Tesla’s labor dispute in the country.
Tesla Sweden’s Megapack-powered Supercharger station near Arlanda Airport has continued to aggravate Swedish labor union IF Metall. The charging site, located in Arlandastad outside Stockholm, appears to be operating despite ongoing union blockade measures tied to Tesla’s labor dispute in the country.
Comments about the site were shared by IF Metall representatives in remarks to Swedish publication CarUp.
The Arlandastad location includes eight Tesla Superchargers powered by a Megapack battery system. Unlike traditional charging stations that rely on direct grid connections, the site uses a large battery installation to store electricity and power the chargers.
According to the Swedish publication, the setup allowed the station to come online despite sympathy measures from Sweden’s electricians’ union, which has attempted to prevent companies from cooperating with Tesla as part of the broader labor conflict.
IF Metall press manager Jesper Pettersson indicated that the union was not aware that the Superchargers had already been connected and activated.
“We do not know the details around this. But it is further proof of how Tesla systematically finds loopholes to circumvent the sympathy measures through active strikebreaking. Every time this happens it gives us reason to sharpen our conflict measures,” Pettersson said.
Union representatives also noted that the Megapack appears to be charged using electrical cables routed through nearby terrain, though the exact power source remains under review.
The Megapack-powered site has then prompted questions from Swedish labor unions about how electricity is being supplied to the system.
IF Metall has submitted a report to Sweden’s Energy Market Inspectorate asking the regulator to review whether the electricity supply arrangement complies with national regulations. The Megapack is reportedly charged using electricity from a local company, though the provider has not been publicly identified.
Peter Lydell, an ombudsman at IF Metall, previously stated that Swedish law limits electricity trading to companies with proper authorization.
“The legislation states that only companies that engage in electricity trading may supply electricity to other parties. You may not supply electricity without a permit, then you are engaging in illegal electricity trading. That is why we have reported this…
“This is about a company that helps Tesla circumvent the conflict measures that exist. It is clear that it is troublesome and it can also have consequences,” Lydell said.
IF Metall and Tesla Sweden’s conflict has been going on for over two years now.
