SpaceX prepares Falcon 9 booster for eleventh launch and landing [webcast]
SpaceX has confirmed that Falcon 9 is on track to launch another batch of Starlink satellites less than 48 hours after a successful United Launch Alliance Atlas V from a pad just two miles south.
Falcon 9 is now scheduled to launch Starlink 4-9 from Kennedy Space Center (KSC) Launch Complex 39A no earlier than (NET) 9:35 am EST (14:35 UTC) on Thursday, March 3rd. Oddly, unlike Starlink 4-8, which successfully launched 46 Starlink satellites into low Earth orbit (LEO) on February 21st, Starlink 4-9 – following a seemingly identical trajectory – will carry 47 satellites. The reason for the small difference is unclear.
Last month, SpaceX suffered a significant anomaly when a “geomagnetic storm” warmed Earth’s atmosphere, causing 38 of 49 just-launched Starlink 4-7 satellites to prematurely reenter and burn up. In response, while SpaceX hasn’t officially confirmed the change, it appears that all subsequent Starlink missions are being launched to slightly higher parking orbits. In comparison, Starlink 4-4 – a West Coast mission – launched 52 satellites into a 340 x 210 kilometer (210 x 130 mi) parking orbit in December 2021. Starlink 4-7, an East Coast mission, launched 49 satellites into a 336 x 210 km parking orbit on February 3rd, losing three satellites to account for extra performance needed to safely dodge the Bahamas.
Following Starlink 4-7’s space weather calamity, SpaceX – using an identical trajectory – launched 46 Starlink 4-8 satellites (three fewer than 4-7) from the East Coast into a higher 337 x 325 km parking orbit on February 21st. On February 25th, SpaceX also launched 50 Starlink 4-11 satellites (a reduction of two) from the West Coast into a higher 316 x 306 km parking orbit. In short, after Starlink 4-7, SpaceX appears to be sacrificing a few Starlink satellites to launch to parking orbits that are slightly higher and thus slightly more stable.
In theory, this should entirely prevent a repeat of the Starlink 4-7 anomaly while only marginally increasing the amount of time it should take dead-on-arrival satellites to reenter. While doing so increases the number of satellites Falcon 9 can launch, the main reason SpaceX launches Starlink satellites to such low orbits is to ensure that any failed satellites reenter a matter of days to a few weeks after launch instead of the years it could take at their operational ~550 km (~340 mi) orbits.
Of course, that doesn’t explain why Starlink 4-9 is projected to launch one more Starlink satellite than Starlink 4-8. It’s possible that SpaceX is refining its new insertion orbit on the fly and that Starlink 4-9 is headed to a slightly lower destination after data gathered from 4-8 and 4-11. It’s also possible that SpaceX is tweaking some other aspect of Falcon 9’s mission profile or even modifying Starlink satellites (i.e. adding or subtracting mass) – neither of which would be out of the ordinary for the company.
Regardless, Starlink 4-9 is interesting for a few more reasons. First, it will mark drone ship Just Read The Instruction’s (JRTI) first recovery mission since a mistake made by its onboard Octagrabber rocket nearly lead to the loss of an entire Falcon 9 booster in December 2021. That implies that SpaceX has fully determined and rectified the cause of that anomaly and repaired both the drone ship and its robot. To reach its full launch cadence potential, SpaceX needs at least two operational drone ships on the East Coast. Otherwise, in lieu of rare low-performance missions that allow Falcon 9 boosters to fly back to land, SpaceX can only launch one East Coast Falcon 9 mission every 10 or so days and can’t support Falcon Heavy launches that require two at-sea booster landings.
Additionally, SpaceX has confirmed that Falcon 9 B1060 will launch Starlink 4-9. The mission will be its 11th launch and landing attempt, hopefully making it the third Falcon 9 booster to successfully support 11 orbital-class launches after B1051 and B1058. Together, that means that 3 (15%) of the 19 Falcon 9 Block 5 boosters SpaceX has debuted will have singlehandedly supported 33 (37%) of the 89 Falcon 9 launches the company has completed since May 2018. It’s difficult to imagine a more resounding affirmation of SpaceX’s work on reusability.
Tune in to SpaceX Starlink 4-9 webcast around 9:20 am EST (14:20 UTC) on Thursday, March 3rd to watch the launch live.

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.
