SpaceX Falcon rocket aces 100th consecutive rocket landing
SpaceX has successfully launched its first batch of next-generation Starlink V2 satellites, likely kicking off a new era of affordability for the constellation.
Simultaneously, demonstrating just how far SpaceX is ahead of its competitors and the rest of the spacefaring world, the Starlink 6-1 launch culminated in the 100th consecutively successful landing of a Falcon rocket booster. As a result, SpaceX’s landing reliability now rivals the launch reliability of some of the most reliable rockets ever flown. That extraordinary feat bodes well for SpaceX’s next-generation Starship rocket, which is designed to propulsively land humans on the Earth, Moon, Mars, and beyond.

SpaceX’s landing reliability milestone is made all the more impressive by the lack of immediate competition. More than seven years after SpaceX’s first successful Falcon 9 booster landing and six years after the company’s first successful Falcon booster reuse, Falcon 9 and Falcon Heavy are still the only reusable orbital-class rockets in operation.
Blue Origin has had some success reusing the first stage of its suborbital New Shepard rocket. Rocket Lab has also recovered small Electron rocket boosters from the ocean, but it’s yet to catch a booster with a helicopter – a necessity for cost-effective reuse. Many other companies have announced or begun developing their own partially or fully-reusable rockets. But even in a best-case scenario, the most promising of those potentially competitive rockets are still a year or two from their first launch attempts, let alone their first successful recoveries and reuses.
SpaceX debuted the Falcon 9 rocket behind most of its successful booster recoveries and reuses in June 2010. SpaceX recovered a Falcon 9 booster for the first time in December 2015 and reused a (different) booster for the first time in March 2017. It completed nearly all of that risky development work during launches for paying customers.
Even after the first success, many unsuccessful landing attempts followed as SpaceX pushed the performance envelope and discovered new failure modes. Falcon’s most recent landing failure occurred during a Starlink launch in February 2021 and was caused by a hole in a flexible ‘skirt’ meant to keep Earth’s superheated atmosphere out of the flight-proven booster’s engine section.
However, every landing since Falcon 9’s Starlink-19 landing failure has been successful. On February 27th, 2023, almost exactly two years after that failure, Falcon 9 booster B1076 touched down on one of SpaceX’s three drone ships, marking the rocket family’s 100th consecutively successful landing. Starlink 6-1 was also the Falcon family’s 183rd consecutively successful launch, as a Falcon landing failure has never prevented the completion of a mission’s primary objective.
Launch-wise, Falcon 9 and the Falcon family have already become the most statistically reliable rockets in history. Very few rockets in history have managed 100 consecutively successful launches, let alone landings. For example, according to spaceflight reporter Alejandro Romera, the next most reliable American rocket – the McDonnell Douglas Delta II – narrowly achieved 100 consecutively successful launches before its retirement in 2018. The landing reliability of SpaceX’s Falcon rockets is thus tied with the launch reliability of the most reliable American rocket not built by SpaceX.
Additionally, SpaceX Falcon booster landings are now statistically more reliable than the launches of United Launch Alliance’s much-touted Atlas V rocket, which has (more or less) successfully launched 97 times.
Falcon’s landing reliability is an encouraging sign for SpaceX’s next-generation Starship rocket. For Starship to fully achieve SpaceX’s goals, it will eventually need to be able to propulsively land humans on Earth and at other destinations throughout the solar system. SpaceX currently has no plans no plans to develop an independent crew escape system for Starship, meaning that the rocket itself will instead have to demonstrate extraordinary overall reliability. SpaceX executives have stated that Starship will only be deemed safe enough to launch humans once it has completed “hundreds” of successful launches and, presumably, landings.
Falcon has managed 100 successful landings in a row despite large gaps in redundancy. Most landing burns are conducted with a single Merlin 1D engine. Any issue with that engine would likely result in a failed landing. Falcon boosters also have four landing legs and four grid fins powered by a single hydraulic pump. The failure of that pump or one of four legs have demonstrably doomed earlier landings.
Starship’s much larger size and excess performance could provide a larger margin for error and allow for more redundancy. But Falcon has demonstrated that that even a rocket with multiple glaring single-points-of-failure can achieve 100 consecutively successful landings.

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.
