SpaceX’s Starship booster-catching ‘launch tower’ begins to take shape in Texas
Aerial photos show that SpaceX has rapidly begun building the first of two planned skyscraper-sized Starship ‘launch towers’ in South Texas – towers that could one day catch the Super Heavy boosters out of the air with huge arms.
CEO Elon Musk first revealed that outlandish Starship booster recovery plan around the turn of the year, followed three months later by an even wilder claim that the same booster-catching tower could also catch Starships. Around the time the idea was first floated, SpaceX was beginning to build one of two planned towers that might be outfitted with arms in the future. Progress was mostly invisible at first, hinted at only by the presence of a self-propelled drill and a few muddy holes in the right spot.
By mid-March, SpaceX had begun clearing away some of the dirt on top, revealing a beefy foundation with 25 two-foot-thick (~1m) piles buried at least 100 ft (30m) deep in the sandy wetlands. Two weeks later, the foundation has been encased in concrete and the framework for massive base is nearly ready for its first concrete pour.
In other words, SpaceX’s first South Texas launch tower has just begun to take shape and grow vertically. First and foremost, its purpose is to provide an extremely sturdy base with which SpaceX can install Super Heavy boosters on the launch mount and then install Starships on top of those boosters. Standing at least 122 meters (~395 ft) tall from tip to tail without even accounting for the launch mount/stand Starship will attach to, that seemingly simple task ends up being not so simple at all.
Situated less than a mile from the Gulf of Mexico, Boca Chica is typically an extremely windy environment at sea level – let alone hundreds of feet above ground – and the South Texas coast is almost constantly at risk of torrential rain, thunderstorms, hurricanes, and flooding. As far as building giant, sturdy towers and performing work as sensitive and precise as vertically mating rocket stages, it’s hard to imagine a viable launch site with less favorable conditions short of Siberia or the Russian steppe.
According to Musk, SpaceX’s Boca Chica launch tower will have a “hook height” (the distance from the crane hook to the ground) of at least 140m (~460 ft), meaning that the top of the tower’s crane will likely be 150-160m (490-520 ft) tall when configured to mate Starship to Super Heavy.
Beyond those general details and the occasional official SpaceX render of possible launch facilities, not much else is known about how Boca Chica’s launch tower will look and function, particularly with respect to vague plans to catch Super Heavy boosters. However, SpaceX appears to have aggressively turned its attention to building out Boca Chica’s first orbital launch facilities and the progress made in the last two months suggests that it wont be long before what was recently a dirt apron will be ready to support Starship and Super Heavy testing.
According to Musk, SpaceX’s internal goal is to attempt Starship and Super Heavy’s first orbital launch as early as July 2021. If the company continues to work around the clock on rocket’s orbital launch site as it has for the last two months, it’s far from inconceivable that the pad will be ready for that orbital launch debut even if Starship is not. Stay tuned for more updates as the pad and launch tower continue to take shape.

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.
