SpaceX adds a second drone ship to its East Coast rocket recovery fleet
On December 10th, SpaceX’s East Coast rocket recovery fleet added a second drone ship to its ranks in a bid to expand its capabilities to support dozens of annual Falcon 9 and Heavy launches, as well as experimental Starship and Super Heavy booster recoveries.
Formerly stationed out of Port of Los Angeles to support SpaceX’s once-substantial West Coast launch manifest, the need for West Coast launches has rapidly dried up over the last six months. That drought had such a long lead that SpaceX decided to transfer drone ship Just Read The Instructions (JRTI) through the Panama Canal, moving the vessel several thousand miles from Port of Los Angeles to Port Canaveral, Florida.
JRTI made it through the Canal several months ago and headed East towards Florida before making an intriguing and lengthy pit stop in a Louisiana port. While there, marine engineers and technicians performed a number of unknown tasks presumed to be a scheduled period of inspections and maintenance. In the last few weeks JRTI spent in Louisiana, SpaceX loaded the drone ship with more than a dozen huge generators and power controllers, as well as six massive maneuvering thrusters.
Although perspectives were lacking while JRTI was docked in LA, it was clear that some (or all) of the new hardware was meant for the drone ship, indicating that the rocket recovery platform could be in for some major upgrades. The aforementioned thrusters are much larger and appear to be heavier than JRTI’s former blue azimuth thrusters, four of which also adorn Florida-based drone ship Of Course I Still Love You (OCISLY).
Those massive thrusters are presumably meant for JRTI (and possibly OCISLY). The fact that they have been delivered alongside an even larger number of generators – far more than are usually present on SpaceX drone ships – indicates that their power output is probably larger, too. It’s not clear how much more powerful they are but one goal is unequivocal: with more powerful thrusters, SpaceX’s drone ships should be much more tolerant of bad weather, meaning that SpaceX will be able to launch Falcon 9, Falcon Heavy, and Starship without having to worry as much about the weather hundreds of miles downrange.
Depending on how powerful they are, it’s also possible that those upgraded thrusters are strong enough to independently power drone ships to and from their ocean landing zones. As of now, SpaceX must contract days of tugboat services to tow drone ships to and from their landing zones, by far one of the biggest recurring costs for booster recoveries. If a major power supply upgrade and much larger thrusters are indeed enough to enable independent cruise capabilities, it could significantly streamline SpaceX’s drone ship recovery efforts, cutting costs and increasing flexibility and availability.
It’s hard to say why drone ship JRTI only brought six new thrusters with it, given that SpaceX’s East Coast fleet now has two drone ships and four thrusters are needed to enable stationkeeping on just one of them. Perhaps two more thrusters are on backorder and will be delivered directly to Port Canaveral. More likely, only one drone ship – likely JRTI – will initially be upgraded with new thrusters and power equipment, leaving two spare thrusters in case those installed are damaged by recovery attempts or fail for more mundane reasons.
In the past, drone ship OCISLY has suffered a handful of recovery anomalies that forced SpaceX to replace the vessel’s blue azimuth thrusters and their associated hydraulic equipment. In some cases, a lack of replacement thrusters lead SpaceX to scavenge drone ship JRTI, leaving the ship without thrusters for several months. With these latest upgrades, SpaceX has presumably learned from those past mistakes and ensured that several spare generators and thrusters are on hand.
Given that SpaceX has yet to install those upgraded thrusters or generators on either JRTI or OCISLY, as well as the general uncertainty surrounding their purpose, it’s safe to say that the next several weeks will be exciting. For now, it’s unknown when JRTI will be ready to support its first East Coast rocket recovery, but there will be plenty of launches to choose from once she is.
With two drone ships now stationed out of Port Canaveral, SpaceX will be able to support a more capable Falcon Heavy configuration, expending the center core while recovering both side boosters at sea. SpaceX will also be able to attempt experimental Starship and Super Heavy drone ship landings while still having a spare ship to support its regular Falcon 9 missions. Most importantly, two drone ships will allow SpaceX to reach launch/landing cadences and turnaround times previously impossible with a single ship, an absolute necessity if the company hopes to achieve its goal of ~24 Starlink launches on top of 10+ commercial launches in 2020.

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:Â
“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.Â
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.Â
“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.Â
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.Â
“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.Â
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.
