SpaceX has completed its 60th operational Starlink satellite launch after a rare string of scrubs.
Flying for the 6th time just 66 days after its 5th launch, Falcon 9 booster B1067 lifted off with 54 Starlink satellites on SpaceX’s Starlink 4-34 mission at 8:18 pm EDT, Sunday, September 18th. Five days prior, after unknown issues triggered a delay from a planned September 11th launch attempt, SpaceX attempted to launch the mission for the first time on September 13th.
About an hour before liftoff, lightning conditions forced the company to call off the attempt. On September 14th, also about an hour before liftoff, weather forced SpaceX to call off the second attempt. On September 15th, the third attempt was aborted (by weather) just 29 seconds before liftoff, followed by a fourth weather-related scrub about a minute before liftoff on September 16th. Only after a fifth attempt on September 17th was preempted by a delay to September 18th did SpaceX finally find a gap between Florida’s summer weather.
With dozens of Starlink launches beginning to blur together and SpaceX’s Falcon 9 continuing a relentless and potentially record-breaking streak of successes at a pace that could soon make it the fastest launching rocket in history, it’s hard to be surprised that Starlink 4-34 was completed without issue. Falcon 9 B1067 ascended under power for about three minutes, sent the rest of the rocket on the way to orbit, coasted into space, and returned to Earth with SpaceX’s 68th consecutively successful booster landing.
Falcon 9’s underappreciated upper stage continued into an orbit around 300 kilometers (~190 mi) up, spun itself up end over end, and deployed a 16.7-ton (~36,900 lb) stack of 54 Starlink V1.5 satellites all at once. Following the quick deployment, the rocket’s pair of reusable fairing halves were likely still 10 or 20 minutes away from touching down on the Atlantic Ocean under their GPS-guided parafoils, where they will eventually be scooped out of the water for future flights.
Starlink 4-34 was SpaceX’s 42nd launch of 2022, maintaining an average of one launch every 6.2 days since the year began. It leaves more than 3000 working Starlink satellites in Earth orbit, likely meaning that a majority of all working satellites are owned and operated by SpaceX less than three full years after the company began operational launches.
Up next, Next Spaceflight and Spaceflight Now report that SpaceX has two more Starlink launches (4-35 and 4-36) tentatively scheduled before the end of September. As of September 15th, both reported that those missions were working towards launches on September 19th and September 26th – nothing unusual for SpaceX in 2022.
What was unusual, however, was both unofficial manifests’ agreement that SpaceX intended to use the same pad – Cape Canaveral Space Force Station’s LC-40 – to launch Starlink 4-34, 4-35, and 4-36. Even assuming that those schedules were predicated upon Starlink 4-34 launching on September 13th, before all of its weather delays, SpaceX would have had to break LC-40’s 7.7-day turnaround record by around ~25% and complete a second launch just seven days after that.
Starlink 4-34’s delays have thrown that plan into question, but the fact that SpaceX thought it was possible in the first place suggests that the company has plans to squeeze even more performance out of LC-40 – already its most important pad from the perspective of launch cadence. Launch photographer Ben Cooper now reports that Starlink 4-36 could launch in late September or October. If it slips into October, SpaceX has a rapid-fire pair of customer satellite launches scheduled on October 5th and 13th that will probably take precedent over any internal Starlink mission.
With only 16 days left before LC-40’s next commercial launch and NASA’s Crew-5 launch taking over SpaceX’s other East Coast pad until October 3rd, SpaceX would have to launch Starlink 4-35 and 4-36 just four or five days apart (and one just 4-5 days after Starlink 4-34) to avoid delaying one of the Starlink missions well into October, avoid unnecessarily delaying commercial launches for paying customers, and ensure that those customers don’t have abruptly agree to be commercial guinea pigs for extra quick LC-40 turnarounds.
Starlink 4-35 is now tentatively scheduled for September 23rd, making a Starlink 4-36 delay more likely but not fully ruling out a launch attempt before the end of the month.

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.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
