SpaceX ship headed 1000 kilometers out to sea for expendable Falcon 9 launch
Update: SpaceX has called off Monday’s launch attempt for what appears to be technical reasons and will try again on Tuesday, November 22nd.
A SpaceX recovery ship is headed more than a thousand kilometers downrange to support the second expendable Falcon 9 rocket launch in nine days.
No earlier than (NET) 9:57 pm EST (02:57 UTC) on Monday, November 21st, a Falcon 9 rocket is scheduled to lift off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad carrying the Eutelsat 10B geostationary communications satellite. For unknown reasons, the French communications provider paid extra to get as much performance as possible out of Falcon 9, requiring SpaceX to expend the rocket’s booster instead of attempting to land and reuse it.
The mission will be Eutelsat’s third Falcon 9 launch in less than three weeks and will wrap up a trio of launch contracts the company secretly signed with SpaceX to move satellites off of competitor Ariane Group’s unavailable Ariane 5 and delayed Ariane 6 rockets. In a rare coincidence, Eutelsat 10B will also be SpaceX’s second expendable Falcon 9 launch in a row and the third Falcon launch to expend a booster this month. But like those two other missions, not all of the Falcon rocket tasked with launching Eutelsat 10B will be lost.
While SpaceX’s spectacular Falcon booster recovery and reuse usually takes center stage, the company has also managed to become the first entity in the world to successfully recover and reuse the deployable nosecone (fairing) that protects satellite payloads during launch. More importantly, Falcon fairing recovery and reuse have quietly become routine, reliable, and even accepted by an increasing number of paying customers. Out of 52 Falcon rockets launched in 2022, a minimum of 40 used at least one reused fairing half, and four of those 52 launches carried Dragon spacecraft (no fairing).
By all appearances, the performance penalty added by the extra mass of the hardware needed to recover Falcon fairings is also so minor that SpaceX can still recover fairings even when a given mission requires the company to expend a Falcon booster. That’s become especially clear within the last few weeks.
On November 1st, a SpaceX Falcon Heavy rocket lifted off for the fourth time ever, and intentionally expended one of its three first-stage boosters for the first time. Despite the booster’s disposal and record-smashing speed at main engine cut-off (MECO; 4 km/s or 8900 mph), SpaceX still managed to recover both of Falcon Heavy’s hypersonic fairing halves after they reentered Earth’s atmosphere and splashed down in the Atlantic Ocean almost 1500 kilometers (~930 mi) downrange. Eleven days later, SpaceX expended a Falcon 9 rocket to launch two Intelsat communications satellites. Once again, both fairing halves were recovered – this time around 960 kilometers (598 mi) downrange.
Aiming for a region 1015 kilometers (630 mi) downrange, Eutelsat 10B’s fairing halves have the potential to travel further than any other piece of Falcon hardware before a successful recovery.
Compared to booster recovery, fairing recovery is more of a convenience than a necessity, and was pursued partially because it allowed SpaceX to avoid dramatically expanding its fairing production facilities in Hawthorne, California. Each Falcon Block 5 booster reuse likely saves SpaceX tens of millions of dollars, while CEO Elon Musk once implied that a standard Falcon fairing half costs about $3 million to build.* But given that SpaceX is now routinely reusing fairing halves five, six, or even seven times in two to three years, it’s likely that each fairing recovery still saves SpaceX a few million dollars.
*Musk specifically said that the fairing represents about 10% of the cost of a new Falcon 9 rocket. That cost could be higher than SpaceX’s Falcon 9 launch price, which was $62 million in 2017 and has grown to $67 million in 2022.
As was the case with SpaceX’s most recent launch, which made Falcon 9 booster B1051’s 14th mission its last, the company has assigned another old Falcon 9 booster to launch Eutelsat 10B. The mission will be Falcon 9 B1049’s 10th and final launch, ending the career of the oldest booster in SpaceX’s fleet. B1049 debuted more than four years ago in September 2018. Older Falcon Block 5 boosters are generally more finicky and high-maintenance, which partially explains why B1049 will retire after completing four fewer launches than B1051, a booster that’s six months younger.
Tune in below to watch SpaceX expend a Falcon booster for the third time in one month – an unfamiliar ‘first’ for a company famous for landing rockets.

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.
