SpaceX’s recovered fairing spotted sailing into port on Mr Steven
Just 24 hours after gently landing in the ocean, SpaceX recovery technicians have successfully recovered one half of an intact Falcon payload fairing for the first time ever. Photos of the return to Port of San Pedro in Southern California, captured by Teslarati photographer Pauline Acalin, show that the halve recovered is in amazing condition considering its journey from speeds of nearly two miles per second (approximately 30 football fields per second, or more than ten times faster than a commercial passenger jet), to a soft, watery halt.
Despite the fact that SpaceX’s recovery boat, Mr Steven, was unable to catch the fairing as intended, a truly 100% successful recovery using the vessel’s specially-designed net is all but a foregone conclusion. If the fairing can gently land in the ocean looking as good as this article does, avoiding the water entirely should be a relatively simple matter of tweaking recovery hardware and software – a slightly larger parafoil as mentioned by Elon Musk, for example.

This recovery marks the end of yet another successful flight-proven SpaceX launch, this time tasked with carrying the Spanish PAZ imaging satellite and two SpaceX Starlink prototypes into a sun-synchronous orbit around Earth. We’re just two full months into 2018 and SpaceX appears to already be nearing the end of its fairing recovery development program, with operational fairing recovery and reuse the next (imminent) task at hand.
The most important unknown here is just how well SpaceX’s fairing design is able to cope with even brief contact with or immersion in saltwater, a natural corrosive agent. As a Teslarati reader rightly noted, carbon fiber composites do currently see quite a bit of use in boating, apparently no worse for wear in terms of maintainability. However, carbon fiber components on marine vessels are treated and coated with specially-chosen laminates and waterproofing materials to prevent saltwater intrusion. It’s unclear if SpaceX’s fairings include the same sort of treatment, although it can be all but guaranteed that the outside of the fairing is designed to be perfectly sealed against the environment – a necessity to protect sensitive satellite components from local weather and humidity.

Of course, reuse for this particular fairing half may be out of the question given its pathfinder position. SpaceX may destructively analyze and test the recovered fairing to gather as much detail as possible about its condition after a rough reentry and some ocean-floating leisure time. In line with my above speculation, recovery technicians and engineers will judge how much (if any) saltwater managed to get inside the fairing, while also judging the condition of the giant halve’s carbon composite structure. Just like SpaceX chose to display its first successfully landed Falcon 9 booster outside of their Hawthorne, CA factory, they may hold onto this intact fairing as a piece of SpaceX history, maybe even put it on display in or around one of SpaceX’s US facilities.

With the next Mr Steven-led fairing recovery set to occur on March 29, SpaceX will have plenty of additional options to firm up their expertise with the newly successful practice. In fact, the upcoming February 25 launch and “hot” landing of Hispasat 30W – this time on the East coast – could also see its own successful fairing recovery, given the fact that PAZ’s fairing technically survived intact without the use of Mr Steven’s gentler catching mitt. Time will tell!

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.
