SpaceX shifts South Texas focus to Starship’s orbital launch pad
Highlighted by a Wednesday jam-packed with important milestones, SpaceX appears to be shifting its focus in South Texas to the completion of Starship’s first orbital launch pad.
Boca Chica will be the first time in its history that SpaceX has faced the challenge of (or had the opportunity to) build an orbital launch complex from scratch after gaining a great deal of expertise modifying, reactivating, and rebuilding two existing pads in Florida and one in California. SpaceX’s Boca Chica facilities must also support what will be the most powerful rocket ever built (or tested) and a planned flight rate and turnaround capability that drastically exceeds anything the company (or anyone else, really) has attempted.
As a result, the site looks almost nothing like SpaceX’s other launch facilities. On top of the already significant hurdles faced, SpaceX is also attempting to complete its from-scratch facility in record time and work on Starship’s orbital launch site (OLS) really only began in earnest around the start of 2021. That aggressive work schedule has begun to clearly bear fruit in the last few months and arguably reached a bit of a local peak on Wednesday, July 28th.
A Tower Is Born
Kicking off the day after an aborted attempt on Tuesday, SpaceX began what would turn out to be an extremely busy Wednesday around 5am CDT (UTC-5) with the installation of the Starship launch tower’s ninth and final prefabricated section, effectively completing the structure’s skeleton. Unlike all other SpaceX pads, save for Pad 39A’s single-purpose Dragon and Crew Access Arm, Starship’s first orbital launch pad will lean heavily on a massive steel tower.
By all appearances, Starship’s launch tower will host an elevator-like carriage outfitted with several large arms on its exterior and will use those arms to stabilize, stack, fuel, and maybe even catch Starships and Super Heavy boosters. The tower will be integral to routine Starship launch operations, in other words.
With the installation of one last steel segment, that tower grew to a height of ~145m (~440 ft) and isn’t expected to get any taller after a 10m/30ft lightning rod is eventually added. SpaceX’s pad team can now begin the process of finalizing tower construction, ranging from adding cladding on its rectangular exterior and welding all nine steel sections together to filling its four legs with concrete.
Tank and Table
Just a few hours after the start of Tower Section #9 installation, a fleet of SpaceX’s self-propelled modular transporters (SPMTs) left the build site with two major pieces of orbital pad hardware in tow. For the first time in three months, one of those payloads was an OLS propellant storage tank built by SpaceX itself out of parts almost identical to those found on Starship. Since the first two ground support equipment (GSE) tanks were rapidly installed in April, activity on that front has been curiously stagnant.
Since modifications of those tanks began in-situ over the last month or so, the general consensus has been that a fairly minor design flaw or oversight was discovered well after production began, requiring a significant pause to rework and redesign the crucial pad components. In the meantime, work on contractor-built GSE tank shells meant to eventually insulate SpaceX’s thin cryogenic storage tanks continued unabated and one water tank and six shells have already been more or less completed. With any luck, GSE tank #5’s delivery to the OLS means that SpaceX has removed the roadblock(s) and is ready to move into plumbing and tank farm activation.
Simultaneously, a far more significant part known as the Starship ‘launch table’ also left SpaceX’s Boca Chica build site after nearly six months of around-the-clock assembly and outfitting. Designed to secure, fuel, and launch orbital Starships, the launch table has to be able to withstand the ~5000 metric ton (~11 million lb) weight of a fully-fueled Starship, hold Super Heavy in place during static fires and prelaunch ignitions that could produce ~7500 metric tons of thrust, and survive the unspeakable fury of 33 Raptor engines operating simultaneously.
Unlike all other major orbital Starship launch pad parts, the custom launch mount and table’s successful and near-total completion is an absolute necessity for any kind of orbital test flight or full-up Super Heavy static fire. Only part of the tank farm is truly necessary and the vast majority of the tower’s intended tasks can be completed with workarounds if neither are fully ready. Without the launch mount, however, testing much beyond what SpaceX has already accomplished is mostly impossible in the near term.
Raptor Invasion
Finally, while less pressing, SpaceX also accepted delivery of four Raptor engines on top of three more that were delivered to Boca Chica on Tuesday. According to CEO Elon Musk, Starship’s first orbital test flight(s) will happen with a full complement of engines installed, meaning that SpaceX will need to build, qualify, and ship at least 35 new Raptors for a single flight.
SpaceX recently completed assembly of the 100th full-scale Raptor engine at its Hawthorne factory and HQ – an encouraging sign that the engines needed for Starship’s orbital launch debut will be ready for flight sooner than later.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
