Russia quietly shelves development of sole SpaceX Falcon 9-competitive rocket
Russian space agency Roscosmos has indefinitely suspended development of the Proton Medium rocket, once expected to help the country compete with the meteoric rise of SpaceX and the growing field of interested entrants in the commercial launch industry.
As Russia makes a greater push toward Angara rockets, it is sidelining development of Proton Medium, a vehicle ILS hoped would compete head on with SpaceX's Falcon 9. https://t.co/BD6AOusalK

The (probable) death of a rocket
In an extraordinary feat of double-speak, freshly appointed Roscosmos director general Dmitry Rogozin – likely a primary source of Proton Medium’s paused development – explained that Russia’s national rocket program would likely experience the “financial collapse of [its] enterprise” if it chose to build “both old and new heavy-duty rockets” simultaneously. Rogozin clearly implied that Angara – a Russian rocket that has flown once (successfully) in 2014 and has a commercial demand about as close to near-zero as possible – was the “new” rocket that Roscosmos ought to solely pursue.
Indeed, upon analyzing the public specifications of Angara A5 and Proton Medium, the two rockets have near-identical theoretical performance characteristics, with higher geostationary transfer orbit payload capabilities (5-6 tons) roughly comparable to Falcon 9 in the SpaceX rocket’s drone ship recovery configuration. As a result, it certainly would make very little sense for Russia to fund and build two rockets with nearly indistinguishable utility – Rogozin certainly is correct in that regard.
However, the space agency director is dumbfoundingly off-base in his suggestion that Angara – not Proton Medium or other proposed alternatives – is the way forward to a financially sustainable Roscosmos. As he himself notes, “eternal state support [of launch vehicles] is impossible and inefficient,” seemingly indicating that he believes any viable state-funded rocket must eventually become a serious commercial competitor, a necessity for a launch vehicle if it’s to sustain itself beyond subsidies (i.e. guaranteed government launch contracts).

The “old” versus the “new”
The Proton family of rockets – past and present – may not have the most reliable track record or a consistent launch cadence, but nearly any rocket on Earth can lay claim to a more storied launch career when placed next to Angara. Despite the fact that the Russian government itself has funded the development and production of Angara rockets, just a single orbital mission has been launched, and only with a mass simulator (dead weight) as its payload. Since that one-off 2014 launch debut, not even the Russian government itself has chosen to fly state satellites on Angara, instead siding with other successful vehicles in the country’s fleet, including Proton Breeze M and Soyuz-2.
This is almost without a doubt because Angara A5 is the most expensive rocket Russia currently operates, reportedly 30-40% more expensive than Proton M, estimated in 2017 by the US Government Accountability Office to cost roughly $65 million per launch. At roughly a third more than that, an Angara A5 launch presumably costs ~$90 million in a best-case scenario, given that the manufacturing apparatus required to construct the rocket has been maintained on a manifest of exactly zero launches since 2014. In fact, the vehicle was estimated by Russia itself to cost roughly $95 to $105 million per launch back in 2015.

In an interview with SpaceNews in late 2017, the president of the commercial wing of Russia’s space launch program (known as ILS) frankly stated that “[ILS] needs to target something between $65 [million] and $55 million as the price point [for Proton Medium], and the Angara 5 vehicle will not be able to do that.” In the same interview, the ILS president even went so far as to imply that “Proton Medium was being designed as a purely commercial competitor to SpaceX’s Falcon 9.”
While there is a very slim chance that Proton Medium’s development will be revived after Roscosmos’ internal review, it’s far safer to presume that the vehicle is dead, thus killing Russia’s only tenuous hope of fielding a rocket capable of competing with the likes of SpaceX and Blue Origin. While Roscosmos’ goal is to make Angara (an entirely expendable rocket, might I add) more affordable, it anticipates that the rocket would become cost-competitive with Proton no earlier than 2025.

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.
