A SpaceX Falcon 9 rocket has successfully launched 51 upgraded laser-linked Starlink satellites from its Vandenberg Space Force Base (VSFB) – the first mission of its kind out of the company’s west coast launch facilities.
Known as Starlink Group 2-1, the mission debuted the operational design of new V1.5 Starlink satellites with laser interlinks that will eventually let the constellation route its own communications almost anywhere on Earth – regardless of ground station locations. Aside from potentially allowing SpaceX to flout local regulations in countries with oppressive communications restrictions, firewalls, or censors, those lasers will also give Starlink the ability to easily deliver internet to moving vehicles – including aircraft traveling over oceans – and in even the remotest locations with no ground infrastructure for hundreds of miles.
Independent of its main purpose, the Starlink 2-1 mission also saw SpaceX tie its internal Falcon booster reusability record. Following in the footsteps of younger booster B1051, Falcon 9 B1049, which debuted in September 2018, successfully completed its tenth orbital-class launch and landing with Starlink 2-1. Originally scheduled to launch as early as July, apparent hiccups mass-producing new Starlink V1.5 satellites and their laser interlinks delayed the mission by about two months, causing SpaceX to launch just once in 11 weeks preceding the mission.
In comparison, Falcon 9 B1051 debuted in March 2019 and became the first booster to cross the ten-flight mark in May 2021, just 26 months later. B1049 took almost exactly 36 months to accomplish the same feat – almost 40% slower but still faster than any of the four NASA Space Shuttles that successfully reached similar milestones.
SpaceX also says that Starlink 2-1 is the 24th time the company has successfully launched a flight-proven Falcon 9 payload fairing, reusing a normally expendable component that CEO Elon Musk once likened to a pallet of $6 million in cash. Ultimately, the company gave up on efforts to catch parasailing fairing halves out of the air with giant ship-based nets and has instead refocused on perfecting the reuse of fairings that gently land in the ocean. For the most part, that’s been accomplished by designing Starlink satellites themselves to tolerate a much dirtier, louder launch environment than most other spacecraft, letting SpaceX remove sponge-like foam sound suppression tiles normally found inside fairings and worry less about needing to deep-clean the giant nosecones.
Nevertheless, SpaceX has technically launched 150+ commercial payloads – and one major geostationary commsat (SXM-7) – over three launches with flight-proven fairings, suggesting that there is a path to wider commercial acceptance of the brand new technology and the direct cost savings it brings.
With Starlink 2-1 safely in orbit, SpaceX now likely operates more space-based laser interlinks than the rest of the world combined. Eventually, once enough satellites with laser links are in orbit, SpaceX will be able to dramatically expand Starlink coverage almost independent of the construction of new ground stations – a heavily bureaucratic process that has proven to make for agonizingly slow progress in a number of the 15+ countries with active service. Instead of requiring that the satellite a given user terminal (dish) is communicating with be in direct line of sight of a ground station dish to route a user’s communications, thus connecting them to the internet, a constellation with widespread lasers will allow a dish’s active satellite to relay that connection through other satellites.
As a result, ground stations can be significantly further away from the users they end up supporting. Further, given that SpaceX has no plans to stop building new ground stations despite the bureaucratic hell it can involve, a well-linked Starlink constellation will ultimately be able to beat most wired connections by using lasers to route user communications to the ground stations closest to the real-world servers or services they’re trying to access.
Stay tuned for updates on SpaceX’s next polar Starlink launch(es) with ‘space lasers.’

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.
