SpaceX just surpassed ULA to snag an American launch record (and landed a rocket)
SpaceX has successfully completed its 84th Falcon 9 rocket launch (and 52nd booster landing), surpassing the United Launch Alliance’s Atlas V to snag a long-standing American launch record.
At 3:30 pm EDT (19:30 UTC), Falcon 9 lifted off right on time after a seven-day delay and rare one-day slip forward. The 6th Starlink v1.0 mission and 7th Starlink launch overall, Falcon 9 successfully placed another batch of 60 satellites in orbit just 35 days after an almost identical booster suffered SpaceX’s first in-flight engine failure in more than eight years. Thankfully, SpaceX says that it already determined what went wrong on March 18th and the successful launch on April 22nd certainly goes a long way towards confirming its conclusions.
Like all Starlink v1.0 launches, a flight-proven Falcon 9 booster (B1051’s fourth flight) and a new upper stage worked together to send some 16 metric tons (~35,000 lb) of Starlink satellites into a very low Earth orbit (VLEO). Booster B1051 performed exactly as expected on its fourth orbital-class launch, burning for about 2.5 minutes before separating and allowing an expendable Falcon 9 upper stage to continue to orbit with its Starlink payload. About six minutes later, after a successful reentry burn and landing burn, the rocket gently touched down on drone ship Of Course I Still Love You (OCISLY). Seconds later, the upper stage shut down after safely placing 60 Starlink satellites in the correct orbit.
Another six minutes later, the same upper stage successfully deployed all 60 Starlink satellites, allowing them to slowly spread out on there own – a bit like a giant deck of cards with the weight of a small tank.
Aside from serving as an extremely reassuring return-to-flight and return-to-landing for Falcon 9 after an in-flight engine failure and two back-to-back booster landing failures, the successful launch also means that Falcon 9 now holds a significant US rocketry record. In essence, SpaceX’s workhorse rocket is now the most prolific US launch vehicle currently operating, surpassing the United Launch Alliance’s Atlas V. Since August 2002, the ULA rocket has completed 83 (mostly) successful launches.
Debuting more than eight years after Atlas V, Falcon 9 passed the 83 launch mark on March 18th and has now successfully crested 84 launches with its April 22nd Starlink-6 mission. In other words, despite operating less than half as long as Atlas V, Falcon 9 has already completed more launches than the ULA workhorse rocket, averaging one launch every 1.3 months compared to Atlas V’s 2.7 months. While SpaceX’s latest Falcon 9 v1.2 rocket variant has only launched 62 of its 84 missions since it debuted in 2015, it’s still considered slightly more reliable than the famously reliable Atlas V.
In short, SpaceX’s Falcon 9 rocket continues to prove itself to be exceptionally capable and reliable, while also managing to rapidly become one of the most-launched US rockets ever. Given that SpaceX is set on continuously and aggressively increasing the rocket’s launch cadence, Falcon 9 may be just a few years away from becoming the most-launched modern US rocket ever – a title currently held by Delta II (retired in 2018).

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.
