SpaceX’s first orbital-class Starship ‘tank farm’ is almost finished
Roughly six months after the process began, SpaceX has installed the seventh and final custom-built propellant storage tank at Starbase’s first orbital-class Starship launch site.
Built out of the same factory and parts as the steel tanks that make up most of the two-stage Starship rocket’s structure, SpaceX completed the first two of those ‘ground support equipment (GSE)’ tanks in April and wasted no time installing both at Starbase’s orbital launch site (OLS). However, after a strong start, GSE tank work seemingly halted for several months and it wasn’t until August that SpaceX first enclosed one of the then three installed tanks with a sleeve designed to insulate their cryogenic contents. Since then, progress has picked back up and SpaceX has built and installed another three (for a total of six) storage tanks over the last two months.
That work effectively culminated on September 7th with the transport of the farm’s seventh and final GSE tank from build site to launch pad.
Unintuitively known as GSE-8 after SpaceX chose to scrap one of the original seven planned tanks earlier this year, the company wasted no time installing it shortly after its two-mile trip down the highway. GSE-8 is the second of two liquid methane (LCH4) tanks now installed at the orbital launch site and joins another three liquid oxygen (LOx) and two liquid nitrogen (LN2) tanks for a total of seven.
Combined, the OLS tank farm should be able to store more than 2400 tons of LCH4 and 4000 tons of LOx, as well as 2600+ tons of LN2 to be used for ‘subcooling’ (and thus densifying) that propellant well below its boiling point. Ultimately, that means that despite the massive scale of Starbase’s first orbital-class tank farm, it will still only hold enough propellant for a single orbital Starship launch and have to be almost fully restocked after each flight.
Given the logistical nightmare of arranging something like 100+ tanker trucks for each tank farm ‘refill,’ a process that could easily take a week or more on its own, it should come as no surprise that SpaceX is also building a dedicated liquid oxygen and nitrogen plant adjacent to its Starbase factory. On top of liquid natural gas (LNG) refinery and tenuous plans to potentially tap local natural gas wells, SpaceX is clearly well aware of the logistical challenges of regular Starship launches.
While there are no clear signs of the inevitable permitting and environmental reviews it would require, it’s likely that SpaceX will eventually create a brief above or below-ground cryogenic pipeline connecting its propellant factory to Starbase’s orbital launch site(s). If or when implemented, that would allow SpaceX to resupply its two planned orbital tank farms with minimal effort or human intervention beyond the process of producing the propellant.
For the time being, SpaceX will likely rely on a slow but simple parade of tanker trucks to gradually fill its first orbital tank farm. Before even that process is possible, though, SpaceX will need to finish plumbing GSE-8 and several other tanks, install the last two insulative ‘cryoshells,’ and finally fill the annuli between all seven tanks and their shells with an insulative foam-like material known as perlite. Dozens of bags of perlite and several kilns (used to expand the material into low density insulation) are already distributed around the orbital tank farm.
Meanwhile, SpaceX also continues to slowly fill the first two completed OLS tanks (nominally meant to hold LOx) with liquid nitrogen, serving both to test the tanks and pad plumbing and to clean their interiors for liquid oxygen service. Ultimately, while a good amount of work remains, Starbase’s first orbital-class tank farm could be fully ready to support its first Super Heavy booster proof and static fire test campaign just a few weeks from now.

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.
