SpaceX, NASA announce date for next Crew Dragon astronaut launch
SpaceX and NASA have settled on October 3rd for the company’s fifth operational astronaut launch, a mission that will also mark the first time a Russian cosmonaut flies on Crew Dragon.
Initially scheduled to launch in early September, NASA announced in July that SpaceX’s Crew-5 launch was slipping to late September after the company accidentally ran its new Falcon 9 rocket booster into a bridge. Luckily for SpaceX, the incident only damaged the top of the booster and was easily resolved with a replacement interstage, but the unplanned repairs still took time and delayed the start of qualification testing in McGregor, Texas.
Ultimately, the damage triggered a delay of about a month, pushing the launch to September 29th. About a month later, NASA and SpaceX have refined that date to 12:55 pm EDT (16:55 UTC) on October 3rd to ensure “extra separation with spacecraft traffic” at the busy International Space Station (ISS).
After such an inauspicious start to its life outside the walls of SpaceX’s Hawthorne, California factory, Falcon 9 booster B1077 was repaired and completed a 78-second static fire test without issue in early August. As of now, the booster is likely almost ready to ship from McGregor, Texas to Cape Canaveral, Florida if it hasn’t left already.
Crew-5 is the second Dragon mission in a row to be significantly delayed by issues with SpaceX hardware after CRS-25 – an uncrewed space station cargo delivery – slipped from June 9th to July 11th because of a leaky Cargo Dragon thruster. Delays of more than a few days caused by SpaceX’s pad, rockets, or spacecraft have become a rarity as the company gains more and more near-term experience operating them around the clock.
In a strange decision, NASA also decided to uphold old plans to swap seats between Soyuz and Commercial Crew vehicles, allowing a Russian cosmonaut to fly on Crew Dragon as the country continues to commit war crimes, kidnap and expatriate vast numbers of legal citizens, and terrorize tens of millions more with its illegal war on Ukraine. Worse, Russia has repeatedly used the International Space Station and its cosmonauts to disseminate propaganda about the war and boast about the new territories it continues to steal from the sovereign nation. Nonetheless, NASA has allowed the deal to continue, and Russian cosmonaut Anna Kikina is on track to launch alongside NASA astronauts Nicole Mann and Josh Cassada and Japanese (JAXA) astronaut Koichi Wakata.
Crew-5 will be SpaceX’s eighth astronaut launch overall, seventh astronaut mission to the space station, and sixth astronaut transport mission for NASA. Once docked to the ISS, Crew-5 will take over from Crew-4, who will depart the station soon after in their own Crew Dragon and return to Earth sometime in October.
Due to a string of issues that have caused years of delays for Boeing’s Starliner spacecraft, which was developed simultaneously alongside SpaceX’s Crew Dragon as part of the NASA Commercial Crew Program, SpaceX has been tasked with continuously ensuring the presence of NASA astronauts at the ISS since November 2020. Equivalent to Crew Dragon’s May 2020 Demo-2 mission, Boeing’s first crewed Starliner flight test (CFT) is scheduled to launch no earlier than (NET) February 2023. SpaceX is thus guaranteed to be NASA’s sole path to the ISS until Q3 or Q4 2023, but that period could easily stretch into 2024 if Boeing runs into any additional issues with Starliner over the next year.

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.

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.
