European spacecraft converge on the US for rides on SpaceX rockets
Thanks in large part to delays suffered by Arianespace’s next-generation Ariane 6 rocket, a small fleet of European satellites are simultaneously converging on the United States to hitch rides into orbit with SpaceX.
SpaceX launching European payloads is nothing new. The company has occasionally launched spacecraft built in Europe for European space agencies or companies, but the combination is exceedingly rare. For several reasons, however, what was once alien is beginning to become commonplace, and that fact is about to be made even clearer over the remainder of 2022.
SpaceX kicked off a string of six or seven launches of spacecraft built by or for Europe on October 15th. Over the weekend, the company’s workhorse Falcon 9 rocket – 70 meters (230 ft) tall, 3.7 meters (12 ft) wide, and capable of producing up to 770 tons (1.7M lbf) of thrust at liftoff – successfully launched the Hotbird 13F communications satellite into a geostationary transfer orbit (GTO) for the French satcom company Eutelsat.
Hotbird 13F is the first of three Eutelsat satellites the company secretly agreed to launch on SpaceX rockets. Hours after its twin’s launch, Hotbird 13G arrived in Florida in a custom Airbus Beluga XL transport jet (its first visit to the US since 2009) and will soon begin preparing for its own ride on a SpaceX rocket as early as November 2022. Eutelsat 10B, also on track to launch on a Falcon 9 rocket sometime in November, likely left France for Florida on an oceangoing Arianespace ship on October 12th.
Normally, selecting the launch provider for communication satellites that cost eight or nine figures is accompanied by a press release and plenty of celebration. That the European Space Agency, Eutelsat, Airbus, and Thales Alenia said next to nothing until the last moment says a lot about how all parties involved really feel about transferring three of their satellites onto SpaceX rockets. Originally, all three were intended to launch on Arianespace’s rockets: Eutelsat 10B on one of the last Ariane 5s and Hotbird 13F and 13G on one of the first Ariane 6s.
It’s not entirely clear why Ariane 5 wasn’t able to launch Eutelsat 10B, but it’s unsurprising that partners ESA, Thales Alenia, Airbus, and Eutelsat decided to move Hotbird 13F and 13G to Falcon 9. The Ariane 6 rocket meant to launch both satellites simultaneously is years behind schedule, and its launch debut recently slipped even further from late 2022 to sometime in 2023. Originally scheduled to debut in mid-2020, it’s now possible – if not likely – that Ariane 6 won’t be ready to launch until the second half of next year (or even later).
Thanks to those delays, the new rocket will enter the scene with a very busy 2023 and 2024 manifest packed with high-value institutional and commercial payloads from all across Europe. In other words, a pair of semi-commercial communications satellites like Hotbird 13F/13G could have easily been forced to wait for a year or more to launch on Ariane 6. Adding insult to injury, Hotbird 13F and 13G are the first two satellites built under the joint European Space Agency and Airbus Eurostar Neo program, and will now be flying on an American rocket built by a company that is almost singlehandedly responsible for ending a golden era of competitive European launch services.
With confidence in Ariane 6’s debut timing lower than ever, a NASA official recently revealed that ESA is even studying the possibility of launching Euclid – a next-generation two-ton space telescope – on SpaceX’s Falcon 9. Euclid was originally scheduled to launch on one of Arianespace’s Russian-built Soyuz 2.1 rockets (or Ariane 6) in mid-2022. That contract was signed in 2020, six years after Russian President Vladimir Putin reminded the world of his instability, recklessness, and brutality by illegally and unofficially invading Ukraine. In February 2022, after months of obvious buildup, Russia doubled down on its Ukraine offensive with an openly genocidal full-scale invasion. In the aftermath, it kidnapped a batch of European OneWeb satellites, requisitioned a Soyuz rocket the company had already paid for, kneecapped a joint European-Russian Mars mission, and (while mostly mutual) revoked its support of European Soyuz launches.
That has effectively removed Russia as a serious option for European launches or collarboration, leaving several European missions and companies in limbo. Britain’s OneWeb, for example, had an exclusive contract with Russia to launch its entire low Earth orbit (LEO) internet satellite constellation on up to 21 Soyuz rockets. After losing $230 million in the process, the company was forced to abruptly shift gears, and is now on track to launch its first batch of satellites since early 2022 on an Indian SLV-3 rocket. One of at least two SpaceX Falcon 9 missions could follow as early as December 2022. Unless Ariane 6 aces its launch debut in the near future, many more European payloads could find themselves in similar positions in 2023 and 2024.
Meanwhile, several other European-made payloads are preparing for Falcon 9 launches. While these payloads have been assigned to SpaceX rockets from the start, they still demonstrate just how big of a bite the US startup has taken out of the European launch industry. Most recently, the joint NASA-ESA-CSA Surface Water and Ocean Topography (SWOT) spacecraft was flown from France to California on October 17th. Falcon 9 will launch SWOT from the California coast as early as December 2022.
Soon, Japanese startup ispace’s first HAKUTO-R Moon lander – largely assembled, tested, and propellant by France’s ArianeGroup – will be transported from Germany to Florida for a November 2022 SpaceX launch. Germany’s second and third SARah radar satellites could head to the US shortly for a Falcon 9 launch tentatively scheduled as early as the final days of 2022 or early 2023. Finally, SpaceX could complete its first OneWeb launch around the same time.

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.
