SpaceX schedules first East Coast Starlink launch in half a year
In just a few days, SpaceX’s next Starlink mission has gone from a complete mystery to a firm launch date.
Set to be SpaceX’s first Starlink launch in almost two months and first East Coast Starlink mission in almost half a year, the launch effectively came out of nowhere with a single week’s warning. For mostly unknown reasons, after completing an unprecedented 13 Starlink launches carrying almost 1000 satellites into orbit in the first five months of 2021, SpaceX has launched just one more batch of Starlink satellites in the last five months. Initially, mid-year, a brief delay of a month or two was expected as SpaceX prepared to debut the next generation of Starlink satellites on the West Coast.
Without explanation, that pause soon ballooned to four months and Starlink launches from Florida unexpectedly ceased in the meantime. Finally, on September 14th, SpaceX completed its first dedicated West Coast Starlink launch, delivering the first 51 new laser-linked Starlink V1.5 satellites to orbit. Again, oddities continued to abound in October as a second West Coast Starlink launch initially scheduled mid-month was delayed indefinitely – and remains so almost a month later.
As of just a few days ago, SpaceX still had no Starlink missions with firm launch dates. However, on November 4th, a sooty Falcon 9 booster (B1062) with a shiny new second stage attached was spotted rolling down Kennedy Space Center (KSC) road on its way to SpaceX’s other Cape Canaveral LC-40 pad. Given that Pad 39A was already occupied with a Falcon 9 rocket and Crew Dragon spacecraft scheduled to launch four astronauts as early as November 10th and that the next mission clearly on SpaceX’s East Coast manifest was more than a month away, a surprise Starlink mission was the only obvious explanation.
Indeed, just a day after that surprise rocket transport, hazard areas published by the Cape Canaveral’s 45th Space Wing confirmed that SpaceX had scheduled a Starlink launch no earlier than (NET) 7-8am EST (12-13:00 UTC) on Friday, November 12th. Oddly, instead of the polar “Starlink 2-2” launch most observers were expecting, the range hazard area announcement was for a mission called “Starlink 4-1,” raising further questions about SpaceX’s new naming scheme.
In simple terms, the first ~4400-satellite phase of SpaceX’s Starlink constellation is split into five groups of satellites – known as shells – with different orbital altitudes and inclinations (the orbit’s tilt). In May, SpaceX’s most recent East Coast Starlink launch effectively completed the first of those five shells. With Starlink V1.5’s September debut, SpaceX also debuted a new naming scheme, deeming the mission Starlink 2-1 – the first launch of the second shell. Based on the inclination implied in Starlink 4-1’s hazard warning, Shell 4 refers to a second group of 1584 satellites almost identical to Shell 1, while Shell 2 is a semi-polar group of 720 satellites. That means that Shells 3 and 5 are sets of either 340 or 158 satellites at slightly different altitudes in polar orbit and will likely be the last Phase 1 Starlink satellites SpaceX launches.
Unlike Shell 1’s Starlink V1.0 satellites, Shell 4 is expected to use Starlink V1.5 satellites with laser interlinks that will eventually allow the constellation to route communications entirely in orbit, limiting the need for ground stations that are both expensive and a bureaucratic nightmare to construct and operate.
Serving as a final confirmation of the imminent Starlink launch, SpaceX service ship Bob departed Port Canaveral with drone ship A Shortfall of Gravitas (ASOG) under tow on November 7th, joining drone ship Just Read The Instructions – already at sea for Crew-3 booster recovery.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
