SpaceX to catch two Falcon 9 fairings at once with twin nets
Over the last three or so weeks, SpaceX rocket recovery technicians and engineers have rapidly modified a second Falcon fairing recovery vessel – known as GO Ms. Chief – to the point that it appears to be almost ready for its first catch attempt.
Essentially a twin of GO Ms. Tree (formerly Mr. Steven), Ms. Chief now features four arms – each with two white support beams – that hold two massive, retractable nets. Ultimately, SpaceX has augmented Ms. Tree with Ms. Chief in a bid to simultaneously catch both parasailing halves of a Falcon 9 (or Heavy) payload fairing after any given launch, the Holy Grail of the company’s fairing recovery program.
A few days after the above photos were taken, SpaceX successfully installed Ms. Chief’s fairing-catching nets and has since taken the ship a few miles beyond Port Canaveral limits for sea trails – presumably meant to verify center of gravity and other performance characteristics. This may or may not have included tests of the newly-modified ship’s fairing recovery mechanism, referring to what is understood to be a direct link between fairing and ship designed to autonomously guide both to the right position for a catch.
Ensuring that that new hardware and software is in good working order is probably even more important than installing Ms. Chief’s arms and nets, evidenced by the fact that it took SpaceX more than 16 months and five failed attempts before Mr. Steven (now Ms. Tree) successfully caught its first fairing. The first success came on June 25th after Falcon Heavy’s third successful launch.

In an encouraging sign, SpaceX’s very next launch (with a fairing) – Falcon 9’s August 6th AMOS-17 mission – marked the second successful fairing catch ever, suggesting that the breakthrough(s) that enabled that first success may be broadly applicable. SpaceX’s next launch with a payload fairing should essentially confirm whether the company’s fairing recovery program has truly reached the end of the tunnel or if there is some distance still to go.
Since AMOS-17, however, SpaceX has been in the midst of a period of launch inactivity unprecedented since Falcon 9’s catastrophic Amos-6 failure in September 2016, triggering a fleet-grounding that lasted four months. That lull has undoubtedly given SpaceX’s recovery team plenty of time to outfit Ms. Chief and perform shakedowns of the vessel’s new hardware, but it also means that there have been zero opportunities for additional fairing-recovery data gathering.

According to publicly-available launch manifests, SpaceX no longer has firm dates for its next launch(es). Previously expected to be one or even two Starlink launches, those missions are now scheduled to launch sometime in October or November. The Kacific-1 communications satellite currently has a (fairly) firm launch target of November 11th, making the mission the best possible bet for SpaceX’s next launch – at least for the time being.
On the plus side, regardless of when SpaceX is able to break its now two-month-long launch hiatus, it appears extremely likely that said launch will become the first attempt at simultaneously catching both Falcon fairing halves. If successful, it could quite rapidly pave the way towards fast, low-cost fairing reuse, a necessity for the economic deployment of SpaceX’s Starlink satellite internet constellation.

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.
