SpaceX ties 42-year-old Soviet record with last launch of 2022
SpaceX has tied a 42-year-old record with its 61st and final Falcon rocket launch of 2022.
Also marking the latest in a calendar year SpaceX has launched a rocket, a Falcon 9 lifted off from the company’s Vandenberg Space Force Base (VSFB) SLC-4E pad at 11:38 pm PST, Thursday, December 29th (7:38 UTC 30 Dec) carrying a tiny Earth observation satellite for Israeli company ImageSat International. Built by Israeli Aircraft Industries, the EROS C3 space telescope is the third of its kind and likely weighed just 400 kilograms (~900 lb) at liftoff, utilizing less than 1/40th of Falcon 9’s available performance in a reusable configuration.
The extremely light payload precluded the need for SpaceX to send drone ship Of Course I Still Love You (OCISLY) several hundred kilometers into the Pacific Ocean, likely saving several hundred thousand dollars. Instead, Falcon 9 booster B1061 lifted off for the 11th time, carried EROS C3 and an expendable Falcon 9 upper stage most of the way into space, and then boosted back towards the California coast to land less than a quarter-mile from SLC-4E.
EROS C3 was SpaceX’s 170th consecutively successful Falcon launch, 160th successful landing, and 132nd launch with a reused booster. But more importantly, the mission was also SpaceX’s 61st successful Falcon launch this year, tying a record that hasn’t been touched since 1980.

In 1980, after two decades of gradual buildup, the Soviet Union managed to launch variants of its R-7 workhorse rocket 64 times in one calendar year. 61 of those launches were successful, setting a record that has been left unchallenged for decades. Only the R-7 family ever posed a threat to its own record, managing 55 successful launches in 1988, but its launch cadence – heavily driven by disposable Cold War reconnaissance satellites – plummeted with the fall of the Soviet Union and has never recovered.
Only in 2022, almost half a century later, has the R-7 family finally found a worthy challenger for its annual launch cadence record. That the challenger is a private company that had to legally force its way into parts of the US launch industry is arguably one of the deepest possible condemnations of the relative stagnancy US space launch capabilities experienced after the Apollo Program. But it also makes SpaceX’s achievement – accomplished with rockets that did not exist before the late 2000s – even more impressive.
Similar to the Soviet peak, an extraordinary period during which the R-7 family successfully launched 1181 times in 22 years, there is one main driving force behind the recent surge in SpaceX’s launch cadence. But instead of the Cold War, the force behind Falcon’s rise is SpaceX’s own constellation of Starlink internet satellites. Since operational launches began in November 2019, Starlink satellites were the primary payload on 66 of the last 125 Falcon launches. In 2022 alone, SpaceX launched 34 Starlink missions.
In 2021, SpaceX completed 31 Falcon 9 launches, 17 of which were Starlink missions. In 2022, SpaceX’s 61 Falcon launches nearly doubled that peak year over year. For a few reasons, that annual doubling is unlikely to repeat itself anytime soon, if ever, but CEO Elon Musk has still issued SpaceX a target of 100 launches in 2023 – a 64% increase year-over-year.
Even that target will be a major challenge, but the EROS C3 mission holds a clue about one of the ways SpaceX can squeeze more out of its existing rockets and launch pads without needing to smash records. SpaceX’s busiest pad, Cape Canaveral’s LC-40, managed nine launches in the last three months of 2022. Its Kennedy Space Center LC-39A pad managed 18 launches over the year. Finally, EROS C3 was SLC-4E’s 13th launch of 2022.
While the California pad came in last, it does not have the same cadence constraints (Dragon and Falcon Heavy missions) as Pad 39A. And less than 12 days ago, SpaceX’s West Coast SLC-4E helped launch NASA and France’s SWOT water observation satellite. Having repeatedly demonstrated the ability to launch two Falcon 9 rockets in less than 12 days, SLC-4E has the potential to carry much more weight in the future. If SpaceX can improve the pad’s ease of use, it could feasibly support 20-25 launches per year, and potentially 30+ with further optimization.
With SLC-4E operating at a cadence of 25 launches per year and LC-40 and LC-39A both operating as-is, SpaceX could launch approximately 80 Falcon rockets in 2023. Ultimately, if SpaceX can maintain the Falcon family’s unprecedented streak of successful launches and improve the uptime of its existing pads, it’s hard to see the R-7 family’s annual cadence record making it to 2024. SpaceX also has a clear (but steep) path to 90+ Falcon launches next year, though simply mirroring its 2022 performance would still be an extraordinary feat.

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.
