SpaceX targeting 100 launches in 2023
CEO Elon Musk says that SpaceX is aiming to complete up to 100 launches in 2023 while the company continues to set records in 2022.
In the history of orbital spaceflight, no family of rockets – let alone a single variant like Falcon 9 – has completed more than 61 successful launches in one calendar year. The cadence target Musk is suggesting is unprecedented and would be an extraordinary challenge even for SpaceX, a company that just completed its 50th successful Falcon 9 launch in a little over 12 months. However, it’s less impossible than it sounds.
After a few years of stagnation at a cadence of roughly 15-20 launches per year from 2017 through 2019, and an impressive doubling from 2019 to 2020 as Starlink entered its buildout phase, SpaceX effectively flipped a switch in 2021. 2020 appears to have been a sort of trial run, demonstrating that SpaceX was able to launch one Falcon 9 rocket every two weeks. At 26 launches for the year, it broke SpaceX’s previous record – 21 launches, set in 2018 – by almost 25%. But something changed in 2021.
In the first half of the year, SpaceX launched 20 times, demonstrating an unexpected 50% improvement over 2020’s annual cadence. In the second half of the year, SpaceX had two strange gaps of almost two months each, during which it didn’t once. In the other two months, though, SpaceX launched 11 times, effectively demonstrating another launch cadence improvement of more than 50% over the first half of the year. Finally, SpaceX completed 6 of those 11 launches in a period of 4 weeks near the end of the year – an annual cadence of 78 launches if sustained for a full year.
Thus far, 2022 has been an eight-month extension of the last few weeks of 2021. SpaceX even appears to have improved upon itself again, accelerating its launch cadence throughout the year. In the first half of the year, SpaceX managed 27 Falcon 9 launches, nearly beating the 31-launch record it set in 2021 in half the time and demonstrating an annual cadence of up to 54 launches per year if sustained.
Instead of continuing that already impressive pace in the second half of the year, SpaceX launched six times in July and another six times in August, sustaining an annualized cadence of 72 launches per year for two full months. At the moment, that could be considered a fluke. But if SpaceX manages another six launches in September, which is the plan, it can likely be deemed a new normal for Falcon 9 launch cadence.
From 60 to 100
To achieve 100 Falcon launches in 2023, SpaceX would need to find a way to launch an average of eight times per month, an improvement of 33% over the six-launch months the company appears to be increasingly comfortable with. Likely thanks to intentional planning and overengineering done years in advance of the payoff, SpaceX’s fleet of Falcon launch pads and recovery ships – drone ship landing platforms especially – appear to be capable of achieving that lofty cadence goal.
Assuming all three pads were able to consistently operate at their fastest demonstrated turnaround times with little to no downtime, they could theoretically support around 115 launches per year. SpaceX drone ship availability is another concern, but the current fleet of three ships can theoretically support 100 Falcon 9 landings in one year if each ship is able to recover one booster every 11 days. Of course, achieving such tight margins would require extremely inflexible scheduling and leave almost no margin for error – perhaps just a day or less per launch, on average.
Without significant upgrades, either feat would be extremely impressive on its own. Stacking those challenges, launching 100 times in 2023 would require an extraordinary effort and a good amount of luck. But it’s far from impossible. Gven the abrupt and impressive progress SpaceX has made and continues to make in 2021 and 2022, it’s also a reasonable goal: far from easy but well within reach with some moderate improvements.
Finally, Musk’s calculus may include a number of launches of SpaceX’s next-generation Starship rocket, which would make the task even more achievable for Falcon 9 and Falcon Heavy. Time will tell, and SpaceX’s activity in the last four months of 2022 will make it clear whether 2023’s 100-launch target is truly feasible.

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.
