SpaceX astronaut launch slips into November
Update: A “minor medical issue involving one of [the] crew members” has forced NASA to delay Crew-3 a bit less than four more days from early November 3rd to 11:36 pm EDT (03:36 UTC), Saturday, November 6th. Falcon 9 and Crew Dragon are in good health and will remain vertical at Pad 39A.
Poor sea states and weather conditions along the Falcon 9 rocket’s ‘ascent corridor’ has forced SpaceX and NASA to delay their next joint astronaut launch from Sunday to Wednesday.
While conditions improved soon after, unfavorable orbital mechanics precluded backup launch windows on Monday or Tuesday, pushing SpaceX’s Crew-3 launch and crew rotation mission to no earlier than (NET) 1:10 am EDT (05:10 UTC) on Wednesday, November 3rd. Barring further delays, NASA astronauts Raja Chari, Thomas Marshburn, Kayla Barron, and ESA astronaut Matthias Maurer – all rookies save for Thomas – will ride a new Crew Dragon spacecraft into space atop once-flown Falcon 9 booster B1067 and a new, expendable Falcon upper stage.
Due to the delay, Crew-2 Dragon astronauts Shane Kimbrough (NASA), Megan McArthur (NASA), Akihiko Hoshide (JAXA), and Thomas Pesquet (ESA) will spend several more days in orbit than initially planned as they wait for Crew-3 to relieve them – hence the term “crew rotation.”
Crew-3’s delay means that for the second time in H2 2021, after launching 20 times in just the first half of the year, SpaceX hasn’t launched once in an entire month. Put simply, SpaceX’s internal Starlink launch cadence fell off a cliff in July and hasn’t recovered since. In H1 2021, 14 of 20 launches primarily carried Starlink satellites. With just two months left in the year, SpaceX has only launched one Starlink mission in H2 2021 and twice otherwise. Crew-3 will be the company’s fourth Falcon 9 launch in as many months.
It’s unclear just how much of that downtick has been a conscious decision made by SpaceX but odds are good that whatever is causing it is largely outside of the company’s control or, at least, is not intentional. One clear possibility is that SpaceX has run into significant issues while attempting to finalize, qualify, and mass-produce new space lasers designed to allow Starlink satellites to route communications without ground stations. So far, SpaceX has only launched one batch of 51 new Starlink V1.5 satellites, seemingly ruling out design or qualification issues. That leaves issues with production, which could potentially be hampered by widespread shortages currently affecting most manufacturing industries to some degree.
Most recently, SpaceX indefinitely delayed a second Starlink V1.5 launch previously scheduled in mid-October. According to launch photographer Ben Cooper, SpaceX has no other launches scheduled in November beyond Crew-3 and Starlink 2-3, both of which were initially meant to launch in October. In December, things could potentially pick back up, with NASA’s IXPE X-ray observatory, a European imaging satellite (CSG-2/CosmoSkyMed), Cargo Dragon’s CRS-24 resupply mission, and Turkey’s Turksat 5B communications satellite all scheduled to launch in the last month of the year.

Tesla seen as early winner as Canada reopens door to China-made EVs
Tesla had already prepared for Chinese exports to Canada in 2023 by equipping its Shanghai Gigafactory to produce a Canada-specific version of the Model Y.
Tesla seems poised to be an early beneficiary of Canada’s decision to reopen imports of Chinese-made electric vehicles, following the removal of a 100% tariff that halted shipments last year.
Thanks to Giga Shanghai’s capability to produce Canadian-spec vehicles, it might only be a matter of time before Tesla is able to export vehicles to Canada from China once more.
Under the new U.S.–Canada trade agreement, Canada will allow up to 49,000 vehicles per year to be imported from China at a 6.1% tariff, with the quota potentially rising to 70,000 units within five years, according to Prime Minister Mark Carney.
Half of the initial quota is reserved for vehicles priced under CAD 35,000, a threshold above current Tesla models, though the electric vehicle maker could still benefit from the rule change, as noted in a Reuters report.
Tesla had already prepared for Chinese exports to Canada in 2023 by equipping its Shanghai Gigafactory to produce a Canada-specific version of the Model Y. That year, Tesla began shipping vehicles from Shanghai to Canada, contributing to a sharp 460% year-over-year increase in China-built vehicle imports through Vancouver.
When Ottawa imposed a 100% tariff in 2024, however, Tesla halted those shipments and shifted Canadian supply to its U.S. and Berlin factories. With tariffs now reduced, Tesla could quickly resume China-to-Canada exports.
Beyond manufacturing flexibility, Tesla could also benefit from its established retail presence in Canada. The automaker operates 39 stores across Canada, while Chinese brands like BYD and Nio have yet to enter the Canadian market directly. Tesla’s relatively small lineup, which is comprised of four core models plus the Cybertruck, allows it to move faster on marketing and logistics than competitors with broader portfolios.

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.
