SpaceX has completed its 21st Falcon 9 launch of 2022, continuing an impressive average cadence of more than one launch per week.
After an unexplained 40-minute delay from 6:20 am EDT, former Falcon Heavy booster B1052 lifted off from Kennedy Space Center Launch Complex 39A shortly after sunrise at 6:59 am EDT (10:59 UTC) on Wednesday, May 18th. Carrying its second batch of Starlink satellites on its third mission as a Falcon 9 boosters and fifth launch overall, Falcon B1052 performed flawlessly, safely carrying a reused Falcon fairing, expendable upper stage, and stack of 53 Starlink satellites most of the way free of Earth’s atmosphere.
B1052 then separated and coasted back to Earth as Falcon 9’s upper stage continued to orbit. About nine minutes after liftoff, the booster touched down on drone ship A Shortfall of Gravitas (ASOG) and the upper stage reached a safe parking orbit, marking the premature end of SpaceX’s official webcast. Starlink satellite deployment – typically anywhere from 20 to 60 minutes after liftoff – now occurs off-camera, with only a slight vocal confirmation and a tweet from SpaceX to verify the most important part of each mission.
Looking beyond the bounds of calendar years, Starlink 4-18 is SpaceX’s 28th successful launch since November 11th, 2021 – a period of six months and seven days or 27 weeks. In other words, SpaceX is already more than half of the way to demonstrating a sustained cadence of one launch per week over a full 12 months, leaving little doubt that the company has the ability to achieve CEO Elon Musk’s lesser goal of 52 launches in 2022. The company’s launch teams, processing facilities, launch pads, Falcon production, and fleets of reusable boosters and fairings have proven themselves fully capable.
The only remaining uncertainty stems from reliability and unknown unknowns. Even the most reliable rocket in the world is a highly complex system that can still fail in thousands of unique ways. After an impressive streak of 130 consecutively successful launch campaigns, Falcon 9 is by some measures the most reliable launch vehicle still in operation. As early as June 2022, however, Falcon 9 will have an opportunity to set the record for most consecutive successes of any rocket in history when it attempts to launch without fail for the 134th time in a row. For now, Russia’s R-7 or Soyuz family of rockets – which have launched close to 2000 times since 1966 – hold the current record of 133 consecutive successes. Technically, if one considers Falcon 9 and Falcon Heavy part of the same family, R-7/Soyuz and Falcon are now tied with records of 133 consecutive successes.
However, the differences between Falcon 9 and Falcon Heavy far exceed the relatively small differences between the many slight R-7/Soyuz variations. Given that the variants of Falcon 9 rockets that began SpaceX’s current streak of success in January 2017 were significantly different than those flying today, the full R-7/Soyuz family and Falcon 9 are more directly and fairly comparable than they might initially appear.
Regardless, SpaceX will have accomplished an extraordinary feat if Falcon 9 does complete its 134th successful launch in a row sometime next month. But simultaneously, R-7’s 133-launch record serves as a reminder that at one point in history, an entirely different rocket family that had been averaging more than one launch per week for almost a decade still failed after 133 successful launches. Modern airliners serve as another good reminder of the inherent instability of complex artificial mechanisms: even though they are statistically one of the safest forms of mass transit humans have ever created, they still occasionally crash.
To assume any such system has become immune to failure after a number of successes is to tempt fate. Nonetheless, with the qualification that there are no guarantees, SpaceX’s performance over the last five years significantly raises confidence in the company’s ability to continue executing and completing orbital launches at a rapid pace throughout 2022 (and beyond) without failure.
Beyond Starlink 4-18, SpaceX is scheduled to launch its own Transporter-5 rideshare mission as early as May 25th, Cargo Dragon’s CRS-25 space station supply mission on June 7th, Egypt’s Nilesat-301 communications satellite on June 10th, and a number of other unspecified commercial launches and Starlink missions in June and July.

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.
