SpaceX Falcon 9 Starlink launch eyes two reusability milestones as new satellite details emerge
SpaceX is set for Falcon 9’s first orbital launch in more than three months. Known as Starlink-1, the mission will launch the company’s heaviest satellite payload ever and feature an impressive array of Falcon 9 booster and fairing reusability milestones.
Flatsat stack
Prior to Falcon 9 going vertical on the launch pad, SpaceX technicians had to construct and encapsulate a massive stack of 60 Starlink satellites, each weighing more than 260 kg (570 lb) apiece. This is the second time SpaceX has launched sixty of the advanced spacecraft, although the satellites that will launch on Starlink-1 feature a number of upgrades and refinements not present on the Starlink v0.9 satellites that launched in May 2019.
Without an identical angle from the Starlink v0.9 mission to compare against, it’s difficult to immediately point out visual differences between v0.9 and v1.0 spacecraft. Still, there are some clear general changes. Most notably, SpaceX appears to have dramatically reduced the area of shiny, metallic surfaces. Additionally, the small downward-facing dishes just left of center in the above image were not obviously present on Starlink v0.9 satellites or SpaceX’s official renders.
Those new dishes could be traditional dish antennas meant to serve as a more basic telemetry, tracking, and command (TTC) communications link for ground controllers. They could even be a prototype of Starlink’s planned inter-satellite laser data links. Regardless, it’s obvious that SpaceX is continuing its preferred cycle of rapid prototyping, flight-testing, and data-based refinement with Starlink.
SpaceX is also focused on dramatically lowering the albedo (reflectivity) of Starlink satellites and working closely with the astronomy and astrophysics communities to minimize any disruption the spacecraft might cause for scientific observations of the night sky. For any part that will be ground-facing during routine operations, this likely involves replacing shiny surfaces with matte finishes and adding dark or non-reflective coatings/insulation where possible, among other potential tweaks.
The more milestones, the merrier
Beyond the many apparent satellite upgrades Starlink-1 is set to debut, the mission will also mark no less than three (or possibly even four) reusability milestones. Falcon 9 booster B1048 has been selected by SpaceX to support Starlink-1 and has already completed three successful orbital-class missions since it debuted in July 2018. Assuming all goes well, B1048 will thus become the first SpaceX booster to launch (and land) four times, an excellent – if increasingly unsurprising – step forward for Falcon 9’s Block 5 upgrade. Falcon 9 B1048 will attempt its fourth landing – this time on drone ship Of Course I Still Love You (OCISLY) – shortly after launch.
Designed to enable up to 10 reuses of each Falcon booster, the successful completion of Starlink-1 will place Block 5 just one reuse away from the halfway point to proving its 10-reuse design. While Block 5 has yet to materialize any tangible improvements in booster turnaround time, an imminent ramp in Starlink launch cadence will hopefully give SpaceX plenty of opportunities to start making progress on that front.
Starlink-1 is also set to mark the inaugural launch of a flight-proven Falcon 9 fairing, essentially putting a bow on the bulk of SpaceX’s challenging fairing recovery and reusability development. Unintuitively, Starlink-1’s fairing previously supported Falcon Heavy Block 5’s April 209 launch debut, meaning that both halves traveled both faster and higher than any halves that previously attempted recovery.
Simultaneously, both halves splashed down in the Atlantic Ocean with no attempt to catch them, meaning that SpaceX has apparently successfully refurbished the fairings despite the fact that their recovery was more or less the worst-case scenario.
Last but not least, Starlink-1 will also mark the first time SpaceX’s just-finished fairing recovery ship GO Ms. Chief attempts to catch a Falcon 9 fairing, as well as the first time two fairing recovery ships – Ms. Tree & Ms. Chief – attempt to catch both halves of a Falcon fairing after launch. The twin recovery vessels departed Port Canaveral, Florida a few days ago and arrived at their recovery point ~750 km (460 mi) downrange on November 10th.
Finally, thanks to the fact that Falcon 9’s fairing is flight-proven, Starlink-1 will additionally feature the first attempted recovery (catch or splashdown) of a flight-proven Falcon fairing. SpaceX could scarcely fit in another milestone if it wanted to go out of its way to do so.
Falcon 9 is scheduled to lift off no earlier than 9:56 am ET (14:56 UTC), November 11th. Weather is 80% GO and SpaceX has a backup launch window around the same time on November 12th with a 70%-favorable weather forecast.

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.
