SpaceX Falcon 9 booster and first thrice-flown fairing return to port [photos]
In a period of just 12 hours last Friday, SpaceX successfully returned Falcon 9 booster B1058 and two payload fairing halves to Port Canaveral and a photographer-laden helicopter was airborne to capture it.
With its safe return to dry land, fairing recovery ship GO Ms. Tree’s bullseye catch of an already twice-flown fairing all but guarantees that the record-breaking payload fairing will have a chance to launch a fourth time in the near future. Meanwhile, Falcon 9 booster B1058 – the first US-built rocket to launch US astronauts since June 2011 – will soon be well on its way to its own fourth flight, likely for one of several dozen Starlink missions SpaceX aims to launch in the next ~15 months.
Aside from placing what CEO Elon Musk says is the last batch of satellites needed to kick off the Starlink internet network’s first public beta tests, the Starlink-12 mission was SpaceX’s 17th this year, leaving the company on track to beat its annual launch record by at least a small margin.
If SpaceX continues to follow its 2020 average of one Falcon 9 launch ever ~16.4 days, the company will likely end the year with 22 missions under its belt, narrowly beating the 21 launches it completed in 2018. If it follows its launch average – ~12.8 days per launch – from just the last four or so months, however, SpaceX could crush its record with some 24 or 25 launches this year. Given recent disruptions from reliably bad weather and a rare last-second launch abort, which trajectory SpaceX will follow over the next ~12 weeks is entirely up in the air.
Regardless of the outcome, though, reusability will have played a foundational role to a degree thus far unprecedented. Barring a major surprise, SpaceX will end 2020 having launched just five new Falcon 9 boosters – three of which will likely launch within the last two months of the year.
For fairing recovery and reuse, 2020 has been an even more groundbreaking, seeing SpaceX (seemingly) begin to find steadier footing with increasingly consistent fairing catches. Impressively, in the measly 11 months since SpaceX first reused a Falcon fairing, nearly a third of all launches and almost half of all Starlink missions have flown with one or two flight-proven halves. Recently, Musk even revealed that SpaceX intends for fairings and boosters to be capable of at least 10 launches each, confirming that Starlink-12’s now thrice-flown fairing half is no fluke.
Drone ship Of Course I Still Love You’s (OCISLY) successful Starlink-12 booster recovery ended an agonizing three weeks of back and forth as SpaceX was tugged in a circle by ULA’s launch priority, technical difficulties, and stormy summer weather. Originally meant to recover Falcon 9 booster B1058 as early as mid-September, the launch slowly slipped its way to October 6th. Beginning in late-September, drone ship Just Read The Instructions (JRTI) joined the fray for its role in SpaceX’s GPS III SV04 launch for the US military, a launch that would also find itself delayed several times.
Two seconds before liftoff, new Falcon 9 booster B1062 automatically aborted its October 2nd launch attempt due to bad pressure readings in at least one of its nine Merlin 1D engines. SpaceX has since taken the rocket horizontal and is likely swapping multiple engines, possibly necessitating a second static fire test before the next attempt sometime later this month. That abort has also delayed SpaceX’s second NASA astronaut launch (Crew-1) from Halloween to mid-November to ensure no commonality.
SpaceX has an absolutely jam-packed fourth quarter ahead of it, ranging from GPS III SV04 and Crew-1 to a Sirius XM radio satellite, a Turkish communications satellite, and the joint NASA/ESA/CNES Sentinel 6A oceanography spacecraft.

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.
